Blockchain And Investor Money For Microgrids Could Give The Utility Death Spiral A Fresh Spin

on March 4, 2018

Four years ago the electric utilities were roiled by predictions they would collapse before an onslaught of solar panels and windmills and batteries at homes and businesses that wouldn’t need utilities anymore.

They pulled themselves together by rallying around the idea that they were uniquely positioned to reinvent themselves as energy-services providers: they have the equipment, the expertise, the personnel, all the convenient connections of the existing grid to serve as exchange networks for all those individual “prosumers.”

But there are signs afoot that microgrids are developing without those utility services, and investors seeking clean-energy opportunities may be pouring money into the new alternatives.

“When you have a microgrid conversation, the people who come to the table aren’t even the utilities,” said Ed Krapels of Anbaric Development Partners, a Boston-based developer of microgrids. “It’s typically the technology companies like Google, like Amazon, that have a completely different idea of how to digitally control an energy system than the utilities have. So it really is the beginning of an enormous change in how the electric system is organized, and it’s a real problem for the utilities that don’t get on board.”

Originally a developer of interstate transmission lines, Anbaric broadened to microgrids because of a convergence of technological forces: distributed generation of solar and wind, cheaper batteries and blockchain cryptocurrencies that allow microgrid participants to buy and sell electricity faster and cheaper than they can through utilities.

Anbaric’s major investor is the Ontario Teachers Pension Plan.

“They own airports and roads and all kinds of infrastructure,” Krapels said. “They would like to be your electricity supplier. And that competition between sources of capital means that the monopoly position of the utilities is coming to an end, and we’re going to have a much more competitive and much more disruptive market.”

Fire-Torn Northern California Becomes ‘Living Lab’ for Microgrids

on March 4, 2018

Greentech-MediaWhen Stone Edge Farm Estate Vineyards & Winery looked to build out a new property in the Mayacamas Mountains straddling Napa and Sonoma counties, the owners found themselves in a multimillion-dollar quandary.

The secluded spot made it an excellent site for a vineyard, but it would cost Pacific Gas & Electric a lot of money to run the 480-volt 3-phase power lines to the property to run the necessary winery equipment. In order to make it work, Mac and Leslie McQuown had to find a more economical way.

Stone Edge isn’t the typical farm. It’s a 16-acre property that uses 10 different kinds of inverters, a fuel-cell “hive,” and seven battery systems, with another on the way. The property was recently in the news for its microgrid system that held up during the devastating fires in Northern California. In January, the microgrid project won a Governor’s Environmental and Economic Leadership Award from the state of California.

The plan to bring power to Stone Edge’s remote vineyard has become another test case for off-grid technology: the Silver Cloud microgrid project. This time, unlike at the original Stone Edge site, there will be no grid backup.

“In the case of Silver Cloud, if the design is not robust enough, we have no failsafe,” said Craig Wooster, general contractor and project manager for the Stone Edge Microgrid Project and CEO of Wooster Energy Engineering. “We’ve got to be able to stand alone.”

Wooster took lessons from the “living laboratory” that is the Stone Edge farm and built out a design for the Silver Cloud microgrid that also incorporates learnings from the fires.

ERCOT Predicts Record-Breaking Summer Demand

on March 3, 2018

The Electric Reliability Council of Texas (ERCOT) has predicted peak demand this summer will break previous records due in part by a booming economy.

Additionally, reserves will tighten due to the recent retirement of older generating units.

Total resource capacity for the upcoming summer is expected to be 77,658 MW. The preliminary summer SARA report includes a 72,974 MW summer peak load forecast based on normal weather conditions for 2002-2016.

This forecast is higher than the all-time summer peak demand record of 71,110 MW set on Aug. 11, 2016. Almost 3,800 MW in new generation resources began operating in 2017, and more than 14,000 MW of resources are planned to be in service by 2020.

California utility SDG&E seeks 166MW energy storage as public emergency response asset

on March 3, 2018

Energy-Storage-NewsSan Diego Gas & Electric (SDG&E), one of California’s three main investor-owned utilities (IOUs), said this week that it will add resilience and backup capabilities to public sector buildings through the procurement of “up to 166MW” of energy storage.

According to a proposal submitted by the utility to regulator California Public Utilities Commission (CPUC), public sector buildings that serve as emergency facilities during emergency situations, providing safety and security in earthquakes, forest fires and other potential disasters, would be supported by seven energy storage projects.

Fire stations, police stations, evacuation sites and emergency operation centres would host the systems. It appears all seven projects have been proposed and to some extent developed already, with their installation planned in phases leading up to completion by 2024.

The utility is also including in the procurement drive a means for nonprofit care facilities to receive incentives to purchase energy storage systems. The Energy Storage Customer Program Pilot, as it will be known, will enable care homes of various types to receive cash sums towards funding system purchases. Currently, California also has in place the statewide SGIP (Self-generation Incentive Program) which offers residential and business customers incentives on purchases of storage systems, but only if deployed in combination with solar PV.

SDG&E said the filing of the proposal is in line with the terms of California legislature Assembly Bill 2868, which was brought into law by CPUC in late 2016. It instructs the state’s investor-owned utilities, bound by another rule, AB2514, to put in place plans to deploy between them 1.35GW of energy storage in their service areas by 2020, to “file applications for programs and investments to accelerate widespread deployment of distributed energy storage systems”. SDG&E said it expects to deploy more than 330MW of energy storage by 2030.

Energy Storage Projects To Benefit Emergency Service Providers And Nonprofits

on March 2, 2018

SAN DIEGO, Feb. 28, 2018 /PRNewswire/ — Today, San Diego Gas & Electric (SDG&E) took another step toward preparing the region for the next major emergency. The company announced plans to add up to 166 megawatts (MW) of energy storage in a proposal submitted to the California Public Utilities Commission (CPUC). If approved, the projects would support public-sector facilities that provide safety, security and emergency services during power grid outages.

The initial projects – seven in total – would be in San Diego County’s rural and urban areas and serve critical public-sector facilities such as fire and police stations, emergency operation centers, and emergency evacuation sites. Providing these public facilities with energy storage systems will help maintain vital operations that serve the public’s well-being. Pending CPUC approval, the plan would be implemented in phases over the next few years with all projects in operation by 2024.

“The innovative projects were developed through close collaboration with local leaders and will significantly increase the resiliency of critical public-sector infrastructure,” said Scott Drury, SDG&E’s president.

SDG&E’s plan also includes an Energy Storage Customer Program Pilot. It would provide incentives for nonprofit care facilities to purchase energy storage systems. Eligible nonprofit low-income care facilities would include, but are not limited to, short or long-term care (hospice, nursing homes, children’s and senior’ homes), group homes for physically or mentally disabled persons, or other nonprofit group living homes.

The proposals are in response to California’s Assembly Bill 2868 which was signed into law in 2016 and allows the company to add distributed energy storage.

Pending CPUC approval, SDG&E would issue a solicitation to identify a third party to administer the Energy Storage Customer Program Pilot. The company expects to launch the program within one year of CPUC approval.

Energy storage is playing a key role in SDG&E’s commitment to deliver clean, safe and reliable energy. By 2030, the company expects to develop or interconnect more than 330 MWs of energy storage. These projects will help deliver more renewables to customers and help strengthen SDG&E’s record as the most reliable utility in the West.

12 hours of energy storage enough for U.S. to run on 80% solar+wind

on March 2, 2018

Scientists at the University of California, Irvine; the California Institute of Technology; and the Carnegie Institution for Science have released an analysis of the U.S. electricity grid managing expanding volumes of intermittent generation in the research journal Energy & Environmental Science.

Geophysical constraints on the reliability of solar and wind power in the United States posits that the U.S. electrical grid could be 80% powered by a solar-heavy+wind power combination using just 12 hours of energy storage to smooth out the variability.

The paper also shows that a wind-heavy+solar power electricity grid would require a nationwide high voltage DC (HVDC) network to move electricity from wind energy dense mid-western regions toward the coasts. The solar heavy network wouldn’t need energy storage with an HVDC network.

To reach a 100% wind+solar U.S. electricity grid would require 3 weeks of energy storage. According to lead author Dr. Matthew R. Shaner.

The U.S. currently uses about 3,900,000 terawatt-hours (TWh) per year. A 12 hour chunk of that would be about 5.4 TWh. At a cost of $350 per kilowatt-hour (kWh), that would cost $1.9 trillion. If each of the 110 million single family homes in the U.S. were to install an energy storage system, and split the total volume needed with the electricity utilities, we’d need approximately 24kWh/home.

About equal to a couple of Powerwalls, a little larger than a Sonnen or 1/2 of a Model 3.

Supplemental information was included with the abstract at the journal website. In it were visualizations of various models, some examples below. The models were mixtures of solar, wind, over sizing these two resources and energy storage. One model, with 100% solar plus 50% over capacity paired with 12 hours of energy storage got us to 93% reliability.

SunPower Turns to Energy Storage for Growth in Tough Times

on March 2, 2018

Greentech-MediaSunPower followed up last week’s tough earnings call with more hopeful news.

The veteran solar manufacturer and developer is launching a commercial energy storage business under the Helix commercial solar brand. It will design, install and operate the battery systems with its own software controls to manage demand charges and optimize solar generation.

In doing so, the company hopes to leverage the experience it has installing and overseeing commercial solar to date, which is unique among commercial storage providers.

“SunPower has a decade of experience monitoring nearly 1.7 gigawatts of commercial solar projects to best understand how they perform, giving us a unique advantage when maximizing the value of a complete solar-plus-storage solution,” said Norm Taffe, SunPower executive vice president for products, in a statement.

SunPower’s focus on a hybrid solar and storage product sets it apart from commercial storage developers like Stem and AMS, which specialize in standalone batteries that reduce customer demand charges and dispatch to serve broader grid needs.

Still, the company’s turn to commercial storage hints at the desperate times that last week’s earnings report detailed.

The U.S. commercial storage market has sustained around 50 projects per quarter lately, almost entirely confined to California, where they rely on the Self-Generation Incentive Program to make deals pencil out.

The ebbs and flows of SGIP disbursements drive wild swings in deployment from quarter to quarter. The U.S. commercial storage market saw a record 13.9 megawatts deployed in Q2 last year, only to plunge 51 percent to 6.8 MW in Q3, according to GTM Research.

But the solar market isn’t looking too balmy either.

Solar Plus Storage Microgrids Bring Relief to Puerto Rico — And Hint of the Future

on March 1, 2018

At the tail end of installing 15 solar plus storage microgrids across Puerto Rico — all of the work charitable — Sonnen and Pura Energia are providing humanitarian relief and a hint of the energy model the island could become.

The latest installation, for a school in the mountain town of Orocovis, comes as over 14 percent of Puerto Ricans remain without power following last Fall’s Hurricane Maria.

Located in a remote, mountain community in southern Puerto Rico, S.U. Matrullas provides K-9 education for some 150 students. Utility grid service was poor and unreliable even before Hurricane Maria struck. The hurricane damaged the school building and homes and wiped out the local grid, as well as water, services infrastructure.

US subsidiary of Germany’s Sonnen and solar company Pura Energia stepped in to fill the void, drawing on equipment and materials donated by the two companies, as well as by other public and private-sector sources. S.U. Matrullas has reopened its doors to students and the community, and now relies entirely on the solar plus storage microgrid, which also includes a backup diesel generator.

The team also has installed solar plus storage microgrids in the communities of La Perla, Loiza, and Morovis. These microgrids are used to power washing machines, refrigerators and some basic electrical outlets. Each microgrid is supporting hundreds of homes whose water was contaminated by the deadly Leptospirosis bacteria.

Microgrid Knowledge spoke with Jose Garcia, Pura Energia’s president and Adam Gentner, Sonnen USA’s director of business development, Latin American Expansion, regarding their charitable microgrid projects in Puerto Rico. They offered insight into what the future may hold in terms of energy infrastructure and services across the US island territory.
