The biggest numbers game in the power sector: Data analytics and the utility community of the future

Software and data are transforming the utility industry and connecting energy users.
One of this century’s most important innovations is the emerging data analytics capabilities that are allowing utilities to use archived and real-time data to make systems more reliable, affordable and clean.
Cost-effective electricity generation from variable renewables is allowing new clean transportation and other electrification initiatives. But they will make the resulting clean energy economy dependent on a burgeoning and complex power system. Automated data analytics can provide the granular, real-time situational awareness to effectively manage it.

 

 

Planning for a Distributed Energy Future
Take an in-depth look at how utilities, consumers, and regulators view the impact of the rapid proliferation of DERs on the grid and utility operations.
The use cases for data analytics are wide-ranging and proliferating. Data analytics-based weather forecasting is prompting pre-hardening of systems against extreme weather events. Data analytics are delivering new services and savings to customers through utility-led energy efficiency programs that cut customer bills and lower utilities’ system costs. In addition, digital simulations are perfecting new hardware before it is installed.

 

 

The unprecedented interconnectedness of systems and available computational power through the cloud are allowing new system-wide data analytics application, the era of siloed utilities is over, and executives are working on creating high fidelity, high quality data structured to be used throughout the company.
No one software will be the answer, as increasing amounts of data and system integration are layered and analyzed by artificial intelligence (AI) with machine learning, he added.
That will lead to the next stage in data analytics in which a utility community pools data and computing power for the deep machine learning AI requires, this will allow shared, curated data and a secure platform to develop solution algorithms.
Data analytics can ultimately lead to a decentralized network that allows peer-to-peer energy transactions in a connected community, energy sector analysts told Utility Dive. But utilities must first fully assimilate and integrate the data and its capabilities.

 

Solar panel efficiency: what you need to know

Simply put, solar panel efficiency (expressed as a percentage) quantifies a solar panel’s ability to convert sunlight into electricity. Given the same amount of sunlight shining for the same duration of time on two solar panels with different efficiency ratings, the more efficient panel will produce more electricity than the less efficient panel.
In practical terms, for two solar panels of the same physical size, if one has a 21% efficiency rating and the other has a 14% efficiency rating, the 21% efficient panel will produce 50% more kilowatt hours (kWh) of electricity under the same conditions as the 14% efficient panel. Thus, maximizing energy use and bill savings is heavily reliant on having top-tier solar panel efficiency.
Many consumers and people in the solar industry consider solar panel efficiency to be the most important criterion when assessing a solar panel’s quality. While it is an important criterion, it’s not the only one to consider while you evaluate whether to install a particular solar panel. Solar panel efficiency relates to the ability of the panel to convert energy at a low cost and high supply rate.

 

 

Most efficient solar panels: the top 5
Here are the top five best solar panel manufacturers in 2019 ranked based on the highest efficiency solar panel they have to offer:
SunPower (22.2%)
LG (21.1%)
Solartech Universal (20.2%)
Silfab (20.0%)
Solaria (19.4%)
The most efficient solar panels on the market today have efficiency ratings as high as 22.2%, whereas the majority of panels range from 15% to 17% efficiency rating. SunPower panels are known for being the most efficient solar panel brand available on the market. Though they will come with a higher price tag, SunPower will often be the consumer favorite for anyone concerned with efficiency as a primal metric of interest. However, check out Exhibit 1 to learn about all the top brands and the most efficient solar panels you can get your hands on.

Maximum Production or Maximum Offset: If your goal is to maximize the amount of electricity your system produces or want to ensure you buy the least amount of electricity from the utility, but the amount of roof space you have available to install solar panels is limited in size, you may choose to install higher efficiency solar panels. This will ensure you get the maximum production from your solar panel system.
Cost vs. Value:  More efficient solar panels tend to cost more than their less efficient counterparts. You may want to analyze whether that upfront cost difference is justified by the increased saving achieved by generating more electricity over the lifespan of your solar energy system. Increased electricity production means you have to buy less power from your utility and in some states, may also generate higher SREC income. The EnergySage Solar Marketplace makes it easy for you to easily compare your savings from solar panels that vary in their efficiency ratings and if their premium price is justified.

Reciprocating Still, New Designs in Alcohol Distillers

The basic concept of a Reciprocation Still is similar to that of a hybrid pot-column still, but the main kettle splits into two equal halves. Each kettle can be heated and operated independently, with both feeding to a shared column.
 
Based on the modular nature of the system, the distiller can break the still down into a couple of smaller stills that will allow for more flexibility, the distiller could execute brandy and whiskey program simultaneously without having to clean the still between each type of spirit run.
 
TWO KETTLES DESIGN
The nature of the design also leads to believe that a higher quality of distillate is actually possible if the kettles are used together. The two colliding streams of vapor from the two kettles would create greater reflux.  This would essentially allow for additional purification of the vapor before it even reached the shared column.
 
The majority of the still consists of stainless steel, with copper reserved for bubble plates and caps housed in the column. Copper is only needed for that vapor interaction.  As a result, it doesn’t reduce distillate quality to manufacture the still in such a fashion. In fact, many of those aforementioned massive column stills follow the same principle. A newer design of the Reciprocator has evolved a bit. A separate, small copper head covers each stainless kettle, with both still feeding to a shared column.
 

 

 

ADVANTAGES OF NEW DESIGN
The dual nature of the design adds a great deal of convenience and flexibility for the craft distiller, who’s often producing a diverse range of spirits. Logistically, it’s a more efficient system, reducing energy needs as it’s faster to heat two smaller kettles as opposed to one larger kettle. This saves both time and money.
 
There are many benefits as well. Made primarily with stainless steel, it’s more affordable to produce than an all-copper still.  Additionally, it has a longer working life span. The rig can produce spirit up to approximately 160 proof on a single run, once again offering efficiency and flexibility. It also happens to be unique and eye-catching. With new craft distilleries popping up by the day, standing out from the crowd in any fashion isn’t a bad idea.
 
As craft distilleries push the boundaries with different mash bills, barrel types and sizes, and nearly every other facet of whiskey and spirits production, it’s no surprise that innovation is cropping up with the stills as well, and for which IESG ENGINEERING LLC keeping working hard to ti improve this design.

Implementation of new technologies in traditional processes

The installation of new technologies implies that the product quality stays the same in any circumstance / all circumstances. The replacement or the extension of the capacity of existing traditional wash stills often lead to new designs under an economic aspect. Economics are often feasible – besides energetically optimization – in the minimizing of the product losses.
With our references in the drinking and power alcohol market we can show outstanding experience using raw materials from different origin. As high capacities are relevant the importance of energy saving processes is emphasized. Our heat integrated processes make use of sophisticated concepts such as mechanical vapor recompression, multi stage distillation and evaporation, heat optimized mashing systems and so forth.
All applied concepts respect the possibility of state-of-the-art technologies without overstressing, as a stable running process is one of our main focusses.
We take over the responsibility for the process mass- and energy balance from the milling to the final products, e.g. alcohol according to specification or DDGS (Dried Distillers Grains with soluble).
The spent residues that result as by-products from fermentation processes from alcohol production are generally called spent wash, vinasse or stillage. These thin liquor stillages contain all the nutrients of the raw materials except for their fermented starch and sugars: i.e. they contain proteins, fat, fiber, minerals etc. in greater concentrations than were present in the original raw material. These liquors can therefore be processed into added-value animal feeds by concentration and, if necessary, drying and crystallization and precipitation of certain seals (e.g. potassium, sodium).
IESG Engineering LLC design allows our clients to create additional value added by-products.

INNOVATION IN DIETARY SUPPLEMENTS

The industry itself has led to new initiatives like the SUPPLEMENT OWL, Good Agricultural and Collection Practices and Good Manufacturing Practices for Botanicals materials, Supplement Compliances Initiative (SSCI), Global Retailer and Manufacturing Alliance (GRMA), and the Botanical Adulterant Program, transparency will only become more prominent.
DNA Analysis has really come to the fore for a numbers of organizations and companies, despite many industry stakeholders continuing to note its limitations.
The NHP business alliance will also bring together industry leaders, regulators and consumers for the development of new industry testing standards, using reliable, affordable DNA-based tools.
Innovative Genomic Analysis are also being applied to medicinal plants used in traditional Chinese Medicine (TCM). A joint venture was announced last year by US-based DNA research firm Illumina and the Institute of Medicinal Plant Development (IMPLAD), based in Beijing.
Some Botanical ingredients suppliers themselves have been developing innovative techniques and embracing novel technology to illustrate their commitment to quality and supply chain integrity. For example, Indena has agreed a strategic cooperation with UK- Based biotech Hyris based on unique sets of reagents for specific DNA sequences (Known as BKITs) and they use a miniaturized portable device for the analysis of nucleic acids (known as the bCUBE).
Probiotic is another obvious category that is applying DNA-based technology, with companies like Dupont driving use of the technology for both identification and enumeration of the microorganisms. While standards PCR (polymerase chain reaction methods can identify strains but not enumerate, Dupont developed a digital PCR method to quantify live cells in a blend, while using power of PCR to identify the strains simultaneously. A proof of concepts was performed with a blend of three L. plantarumstrains.
THE SCIENCE
Moving on the supply chain and quality side of the industry, there are also a number of area that particularly excite and fascinate me, including the microbiome, probiotics and prebiotics, anti-aging (longevity); beauty from within; nootropics, adaptogens, and a few specific ingredients in particular.
Starting with the microbiome, probiotics supplements are outpacing growth in other types of supplements. We have moved well beyond just digestive health, brain health, immune support, weight management, and so on.
There is even research underway in the community to mine the gut microbiota of elite athletes for potential new probiotics (the gut microbiomes of athletes are more diverse than non-athletes).
IESG ENGINEERING LLC has worked in developing new Supplements exploring opportunities there, from immune support to reducing post exercise inflammation and boosting recovery, enhancing protein absorption, antiaging, improve brain health, reduce digestive illness, and we are happy to keep our high quality industrial manufacturing active to develop more products.

NEW APPLICATIONS OF BIOTECHNOLOGY IN THE FOOD INDUSTRY

In the past several years, biotechnology in the food industry has been the central theme of numerous scientific reviews, national and international symposia, and several major reference works (Earle, 1984; Harlander and Labuza, 1986; Jarvis and Holmes, 1982; Kirsop, 1985; Knorr, 1987; Knorr and Sinskey, 1985; Moo-Young et al., 1985; Rehm and Reed, 1983). Reports of significant advances have come from the full spectrum of biotechnology research and development resources: universities and institutes as well as genetic “biotiques” and large food corporations. Important business alliances continue to be formed on a worldwide scale, linking advanced biotechnology research skills with large producers and marketers of food products, principally in the United States, Japan, the United Kingdom, and Europe. These alliances include Amgen/Kodak, CalBio/American Home Products, Genentech/Lilly, Genentech/Corning (Genencor), Interferon/Anheuser-Busch, Molecular Genetics/Upjohn, Synergen/Procter & Gamble, American Cyanamid/Pioneer Hi-Bred, Dupont/Advanced Genetic Sciences, W. R. Grace/ Cetus (Agricetus), Hoechst/Harvard, Monsanto/Genentech, Monsanto/Washington University/Rockefeller University, Roche/Agrigenetics, Beatrice/Ingene, Campbell/DNA Plant Technology (DNAP), Campbell/Calgene, CPC/Enzyme Biosystems, Kraft/DNAP, General Foods/DNAP, Kellogg/ Agrigenetics, Heinz/ARCO, McCormick/Native Plants, Inc., Molson/Allelix, RJR-Nabisco/Escagen, and Seagram/Biotechnica. Corporate boards and strategic planning groups of major food companies now understand the language of biotechnology and can perceive its utility and value; this has been the case with their corporate research departments for years. One thing is clear: The excitement and enthusiasm for biotechnology so characteristic of the pharmaceutical and medical areas in the early 1980s have now begun to hit the food industry with increasing force, and this momentum will likely establish this industry as the largest commercial arena for biotechnology. Companies involved include Archer Daniels Midland, American Home Products, Beatrice, Campbell, Cargill, Corn Products Company, Coors, Chr. Hansen’s Laboratory, Firmenich, General Foods, Heinz, Hunt-Wesson, Kraft, LaBatt, McCormick, Nestle, Pillsbury, Purdue, Procter & Gamble, Ralston, RJR-Nabisco, Staley, Unilever, IESG Engineering LLC, and Universal Foods.
At least three important factors are responsible for this. First, in pharmaceuticals, the feasibility of the biotechnology promise has been established and the commercial reduction to practice (i.e., commercial application) is in place in the marketplace. This was achieved by using many of the same technical concepts and strategies currently envisioned for food industry applications. Second, key advancements in technology continue to be made, principally in molecular genetics, cell technologies, computer-aided protein engineering, bioreactor design, and biosensor/diagnostic technology. These advancements have substantially redefined the technical skills base and broadened the potential applications of biotechnology to foods. Third, within the food industry, reports of successful new applications of biotechnology (e.g., those reported here) add confidence to the prediction that biotechnology may well be the next key source of competitive leverage at the corporate and international levels, and may be the most important single technical consideration in consolidation strategies.
The following paragraphs are a review of new applications of biotechnology in each of the following food-related areas: enzymes, including the processing of cheese; fermentation, including brewing and wine making; agricultural raw materials (e.g., crop plants, meat, poultry, fish) with improved functionality; and plant cell bioreactors for food ingredient production.
IESG Engineering LLC is been working in a variety of biotechnology projects and we are thrilled to be part of a business that is impacting so well in our development as a society.

Biotechnology Applications in Beverage Production

Beverage production is among the oldest, though quantitatively most significant, applications of biotechnology methods, based on the use of microorganisms and enzymes. Manufacturing processes employed in beverage production, originally typically empirical, have become a sector of growing economic importance in the food industry. Pasteur’s work represented the starting point for technological evolution in this field, and over the last hundred years progress in scientifically based research has been intense. This scientific and technological evolution is the direct result of the encounter between various disciplines (chemistry, biology, engineering, etc.). Beverage production now exploits all the various features of first and second-generation biotechnology: screening and selective improvement of microorganisms; their mutations; their use in genetic engineering methods; fermentation control; control of enzymatic processes, including industrial plants; use of soluble enzymes and immobilized enzyme reactors; development of waste treatment processes and so on. Research developments involving the use of biotechnology for the purpose of improving yields, solving quality-related problems and stimulating innovation are of particular and growing interest as far as production is concerned. Indeed, quality is the final result of the regulation of microbiological and enzymatic processes, and innovation is a consequence of improved knowledge of useful fermentations and the availability of new ingredients. IESG Engineering’s projects are working to led to the contributions to this industry as a clear evidence of the growing need for adequate information about scientific and technological progress.

New Technology For Air Conditioning

National University of Singapore researchers have pioneered a new water-based air-conditioning system that cools air to as low as 18º C (64.4º F) without using energy-intensive compressors andenvironmentally  harmful chemical refrigerants.
 
This disruptive type of technology could potentially replace the century-old air-cooling principle that is still being used in our modern-day air-conditioners. Suitable for both indoor and outdoor use, the novel system is portable and it can also be customized for all types of weather conditions.
 
NUS Engineering researchers developed a novel air cooling technology
that could redefine the future of air-conditioning. 
 
Led by Associate Professor Ernest Chua from the Department of Mechanical Engineering at NUS Faculty of Engineering, the team’s novel air-conditioning system is cost-effective to produce, and it is also more eco-friendly and sustainable. The system consumes about 40 percent less electricity than current compressor-based air-conditioners used in homes and commercial buildings. This translates into more than a 40 percent reduction in carbon emissions. In addition, it adopts a water-based cooling technology instead of using chemical refrigerants such as chlorofluorocarbon and hydrochlorofluorocarbon for cooling, thus making it safer and more environmentally-friendly.
 
Adding another feather to its eco-friendliness cap, the novel system generates potable drinking water while it cools the ambient air.
Associate Prof Chua said, “For buildings located in the tropics, more than 40 percent of the building’s energy consumption is attributed to air-conditioning. We expect this rate to increase dramatically, adding an extra punch to global warming. First invented by Willis Carrier in 1902, vapor compression air-conditioning is the most widely used air-conditioning technology today. This approach is very energy-intensive and environmentally harmful. In contrast, our novel membrane and water-based cooling technology is very eco-friendly – it can provide cool and dry air without using a compressor and chemical refrigerants. This is a new starting point for the next generation of air-conditioners, and our technology has immense potential to disrupt how air-conditioning has traditionally been provided.”
Current air-conditioning systems require a large amount of energy to remove moisture and to cool the dehumidified air. By developing two systems to perform these two processes separately, the NUS Engineering team can better control each process and hence achieve greater energy efficiency.
 
The novel air-conditioning system first uses an innovative membrane technology – a paper-like material – to remove moisture from humid outdoor air. The dehumidified air is then cooled via a dew-point cooling system that uses water as the cooling medium instead of harmful chemical refrigerants. Unlike vapor compression air-conditioners, the novel system does not release hot air to the environment. Instead, a cool air stream that is comparatively less humid than environmental humidity is discharged – negating the effect of micro-climate. About 12 to 15 liters of potable drinking water can also be harvested after operating the air-conditioning system for a day.
Associate Prof Chua explained, “Our cooling technology can be easily tailored for all types of weather conditions, from humid climate in the tropics to arid climate in the deserts. While it can be used for indoor living and commercial spaces, it can also be easily scaled up to provide air-conditioning for clusters of buildings in an energy-efficient manner. This novel technology is also highly suitable for confined spaces such as bomb shelters or bunkers, where removing moisture from the air is critical for human comfort, as well as for sustainable operation of delicate equipment in areas such as field hospitals, armored personnel carriers, and operation decks of navy ships as well as aircraft.”
 
The research team is currently refining the design of the air-conditioning system to further improve its user-friendliness. The NUS researchers are also working to incorporate smart features such as pre-programmed thermal settings based on human occupancy and real-time tracking of its energy efficiency. The team hopes to work with industry partners to commercialize the technology.
 
Looks and sounds good. But that discharge temperature looks barely adequate for the developed world’s jaded consumers. Drying the air will make huge difference, cooling the circulating air far enough to condense out the water vapor is a big part of the A/C energy cost. So it looks like a sure half way, first step, kind of thing.
The approach is also a sophisticated look at A/C as its done now. Going to two steps with such impressive results is sure to cause an engineering rethink for current designs marketed in the developed world now. Is it a revolution or disruptive technology? Almost.
Where new installations with capital cost decisions are tight and running expense is a concern, this technology should find a warm reception.

Augmented Intelligence: A new way forward for utilities to unite artificial intelligence with the human workforce

When artificial intelligence is brought up in conversation, the classic idea of a robot versus a human emerges somewhat of an us-versus-them mentality but artificial intelligence works at its best when is machine learning, natural language processing, and robotics is viewed as a partnership with the human workforce. Enter augmented intelligence, which sits at the nexus between artificial intelligence and humans, and revolves around technology helping people to complete their work more efficiently and allowing them to focus more on high-value “human-only” type activities.
Today’s utilities are faced with multiple market disruptions including the proliferation of distributed energy sources, evolving regulatory and policy changes, the increased adoption of energy efficiency products and programs, changing consumer behaviors, and an imperative to modernize their technologies and processes. Faced with these disruptions, utility executives can leverage innovative approaches such as augmented intelligence to position themselves for success.
Exploring the ‘art of the possible’ with machine learning and natural language processing
Capital Budget Planning
Utilities make investments in new equipment by upgrading existing assets, such as transformers and substations, and performing preventative maintenance, all with the goal of improving reliability of service. Current approaches to budget planning require utility engineers to try and analyze hundreds of different parameters from dozens of different data sources to identify the capital investments that will deliver the most improvement to reliability.
Utilizing outage and other operational data, maintenance history, asset types, and load patterns, as well as new nontraditional variables such as DER adoption, energy efficiency program efficacy, augmented intelligence can more systematically and consistently define the most effective ways to deploy capital in modernizing or upgrading the electric network. By analyzing patterns of prior investments that have improved reliability of the grid in the past, and factoring in diminished returns, unsupervised machine learning could reveal the most impactful near-term capital investments in the electric grid to the human workforce.
Damage Assessment and Restoration Activity
After a storm or fire event, utilities typically send crews out to assess the damage to their assets (poles, wires, transformers) and then they prioritize restoration and repair activities. The crews visually review the storm damage and phone in their reports to the storm base, and then they drive to the next area and repeat this activity manually/visually over many days.
Based on a combination of aerial, drone and satellite imagery, augmented intelligence could be used to analyze images to more quickly and reliably assess damage to the grid after a storm (downed wires, damaged poles and transformers), ultimately helping the utility to determine the priority of repairs that would restore power in the fastest, most effective manner.
Electrification of Transport
Electric vehicles (EVs) create a challenge for utilities in planning for load growth. Right now, engineers are trying to predict with disparate datasets and manual analysis which customers on their network will likely purchase an EV, as well as the timeframe. This information is used to predict the network load and help determine if upgrades are needed. For example, if 20 customers are all on the same circuit and they all purchase a Tesla at around the same time, the load requirements on that circuit would increase significantly, potentially causing outages.
Based on consumer behavior (e.g. social media feeds), car dealership sales, local government incentives, augmented intelligence could be used to identify a pattern for consumer and fleet vehicles (e.g. UPS, FedEx, etc.) electric car adoption.  By predicting when a utility customer might purchase an EV, a utility could plan its investment in the electric grid to increase load requirements, thus ensuring no overloads (outages) on a given circuit.
Customer Engagement
When a utility’s call center receives calls from customers, a Customer Service Representative (CSR) may not know the identity of the customer, their past interactions with the utility, nor may they know what the customer might be calling about at that moment, etc. This leads to a poor customer service interaction, and a CSR who is unable to be proactive about how they serve the customer or offer them additional or new services.
Utilizing predictive data analytics, the CSR would be able to identify the customer when they call, and predict why they are calling based on past interactions or specific customer characteristics. This in turn would provide the CSR with the best information to provide a more positive customer experience. The CSR would also be well-positioned to offer additional targeted services, such as energy efficiency services.
Some utility customers (e.g., millennials) prefer not to make a phone call at all. Recent advances in natural language processing (NLP) provide customers with the opportunity to use a chatbot instead of talking to a human being. NLP technology is used to evaluate the text entered in the chat field to automatically answer simple questions (e.g., “How much is my bill this month?”) or direct the customer to a human being for more complex questions (e.g., “Why is my bill high this month?”). In an outage, NLP can also be used to analyze social media content from Twitter, Facebook, and Instagram to improve utility operations situational awareness, which will ultimately allow the utility to provide informed updates to customers.
Virtual assistants, such as Amazon’s Alexa, also stand to transform the customer experience, allowing the customer to be able to ask questions or take actions based on connections with smart home devices or utility systems. For example, “What’s my usage so far this month?”, “What’s my solar contribution to my bill so far this month?”, “Pay my bill” or “Which appliance uses the most electricity in my home?” Taking it a step further, virtual assistants could also develop new skills, providing them with the ability to assist in certain actions (e.g. running the washing machine at the least expensive time of day).
The use of robotics to streamline organizational processes
There are several applications of robotics that utilities could adopt, with all of them providing a combination of cost savings, reducing operational expenditures, and offering better customer service.
Hazardous Vegetation Detection
Vegetation near power lines can cause power outages during severe weather events. Identifying and managing vegetation is a costly and on-going battle for many utilities – when to trim, where to trim and how often.
Autonomous drones could sense and follow the power line routes and automatically identify and mark overgrown points along the route (live video feeds to the cloud, coupled with machine learning). The drone would sense overgrowth and automatically fly a 360 around the area at different altitudes to provide a full view of the extent and type of obstruction. This would provide vegetation crews with specific GPS locations of problem areas so they can systematically plan and manage their vegetation removal actions.
Further, these drones can identify diseased or damaged trees outside of the utility’s typical trim zones for targeted removal. Doing so can be helpful in ensuring that they do not fall down on the power lines and cause outages during a storm.
Regulatory Inspections
Utilities are required to inspect their transmission and distribution power assets on a regular basis for damage, potential issues and environmental impacts.
Autonomous drones could be used to perform visual automated inspections of power assets including substations, transformers, poles, towers etc. After setting an initial starting point, the drone would sense the asset type ( e.g. pole mounted transformer) and then fly a predetermined flight sequence to fully capture a real-time multi-angle view of the asset. In addition to high definition video, drones can be fitted with thermal, inductive, X-ray or magnetic inspection devices for other types of non-destructive analysis. This can be particularly helpful in the future either during nighttime or less than ideal conditions (i.e. wind) too hazardous for humans.
Right now, there are significant hurdles, particularly in the United States, as Federal Aviation Administration (FAA) regulations limit drone operations to “visual line of sight,” meaning that the pilot or an observer must always be able to see the drone while in operation. However, progress is being made to modify the FAA regulations.
Construction & Repairs
When power poles and lines are damaged by storms or accidents, repair crews are dispatched to assess and repair damage by fixing or replacing poles, transformers, and insulators. Autonomous vehicles could be used to deliver tools and replacement parts to specific job sites more cost-effectively and quickly, and have the construction trucks loaded before the start of a shift so utility crews can minimize loading times and maximize construction times. The automated loading drones can record information generated by the autonomous damage assessment drones and determine which tools and spare parts are required to restore service. Again, this minimizes the loading times, and can speed restoration activities.
The road to augmented intelligence
The utility landscape has changed dramatically over the past several years, and as such, utilities have shifted their focus to digitizing existing business processes, meaning that they are layering new technology onto existing processes. However, to become a successful Next Generation Energy company, the path forward must include the integration of augmented intelligence into business processes, enabling them to truly innovate with technology.

 

Residential storage hits new record, deploying 36MWh in Q1

Dive Brief:
Residential energy storage deployments hit a record in the first quarter, according to the latest U.S. Energy Storage Monitor report from GTM Research and the Energy Storage Association.
There was as much grid-connected residential storage deployed in the first quarter, 36 MWh, as was deployed in the previous three quarters, according to the report.
Much of the increase in residential energy storage deployments can be attributed to changing policies in California and Hawaii, which together accounted for 74% of the residential deployments in the quarter, according to the report.

 

 

Dive Insight:
Both California and Hawaii have made changes to their solar programs over the past few years that resulted in reduced net metering compensation, which consequently increases incentives for energy storage.
Hawaii, for example, capped its consumer grid supply program and placed an export moratorium on its consumer self-supply program. Both programs were put in place as alternatives to the state’s net metering program, which was canceled in 2015.
California is transitioning to time of use (TOU) rates, causing greater customer demand for storage because it will give them greater control over their electricity bills, a senior analyst on energy storage at GTM, Brett Simon, told Utility Dive via email.
The combination of California’s TOU rates and the state’s Self Generation Incentive Program (SGIP) makes solar-plus-storage almost competitive with solar-only, based on 2018 assumptions, Simon said, adding that solar-plus-storage will be the superior choice for homeowners on TOU rates within a few years.
Solar-plus-storage is, in fact, emerging as a key driver in the growth of the energy storage market. “More than 95% of all residential storage is solar-paired,” Simon said. It is also an important factor in the commercial and industrial and the front-of-the-meter markets (FTM), he said.
Residential storage systems accounted for 28% of the megawatt hours deployed in the first quarter, but the residential segment was second behind the FTM segment, which accounted for 51% of deployments. The non-residential segment, meanwhile, accounted for only 21% of the deployed MWh.
Overall, 126 MWh of energy storage were deployed in the first quarter, a 26% increase from fourth quarter 2017, but a 46% decline year-over-year. But GTM analysts say fourth quarter 2017 was an anomaly because that is when many of the large energy storage projects needed to offset the gas leaks at Aliso Canyon in Southern California came online.
GTM Research sees the energy storage market approaching the 1 GW mark in 2019 and crossing it in 2020. By 2023, BTM energy storage deployments will account for 47% of the annual market, GTM estimates.
