Total’s wholly-owned subsidiary, Saft, has completed work on a 10MW / 5.5MWh energy storage project in Bermuda that only began in February.

The company, which was featured in Energy-Storage.news last week as it unveiled a new 2.5MWh containerised battery energy storage solution to the European market at Intersolar, has provided the system for utility Bermuda Electric Light Company (BELCO) to deliver spinning reserve and frequency response applications. The island territory has been long dependent on fossil fuel imports, with the passing of an Electricity Act in 2016 marking the start of a process of modernisation.

At the recent Intersolar event, Saft’s Michael Lippert told Energy-Storage.news that in maturing markets, the need for energy is now catching up with the need for power applications. In regions such as the US and Australia, batteries with two to four-hour durations are being sought for solar time shifting or load-shifting as the penetration of solar on the grid goes beyond 20% or more. Nonetheless, in newer markets, the pattern appears to be that short duration storage with high power capabilities is put on the grid first to provide flexibility, such as in this instance.

“The BELCO project continues a long series of successful energy storage deployments by Saft to support island grids since 2003. Saft is committed to provide BELCO with a reliable and high-performance spinning reserve solution as an alternative to its generators,” Saft executive VP for telecoms, transport and grid, Hervé Amossé said.

BELCO’s requirements in commissioning the project were “stringent’, Saft said, with high reliability, low operational cost and guaranteed performance over the asset’s lifetimes all criteria that had to be met. The turnkey system’s power conversion equipment can simultaneously support grid frequency with active power, while also providing reactive power to stabilise voltage.

SAN DIEGO, May 28, 2019 (GLOBE NEWSWIRE) — NeoVolta’s NV14 home energy storage system receives product eligibility approval from the Center for Sustainable Energy for participation in California’s $830 million Self-Generation Incentive Program (SGIP).

The SGIP provides rebates to customers for installing home energy storage systems, which allow solar power to be used all hours of the day, addressing the solar energy duck curve: over production of solar energy during the day and under production at night when electricity rates are most expensive.

By supporting and incentivizing the development of energy storage technologies, SB700 will reduce the costs for energy storage just as other previous rebate programs did for solar power. “What we’re trying to do is create a mainstream market for energy storage, like we’ve done for solar PV,” said Bernadette Del Chiaro, executive director of the California Solar & Storage Association.

“In addition to qualifying for a 30% Federal Investment Tax Credit (ITC), California home owners that install a NeoVolta NV14 can apply for state funds under SB700 to subsidize a significant portion of the cost,” said Brent Willson, CEO of NeoVolta. “Rebates are utility specific and on a first-come first-serve basis. It’s imperative for customers to reserve their incentives before their local utility allocation runs out.”

About NeoVolta

NeoVolta designs, develops, manufactures, sells and installs home energy storage systems and products. The company’s flagship product NV14 is a complete home energy management system, designed with a 14.4 kWh rechargeable Lithium Iron Phosphate battery, a 7,680-Watt inverter, an internal auto transfer switch which allows for grid out operation, and a web-based energy management system with 24/7 monitoring. By storing energy instead of sending it back to the grid, consumers can protect themselves against blackouts, avoid expensive peak demand electricity rates charged by utility companies when solar panels aren’t producing, and get one step closer to grid independence.

U.S. Sens. Susan Collins (R-ME) and Martin Heinrich (D-NM) recently led a bipartisan group of senators in introducing the Better Energy Storage Technology (BEST) Act, which supports grid-scale energy storage research and development.

“Next generation energy storage devices will help enhance the efficiency and reliability of our electric grid, reduce energy costs, and promote the adoption of renewable resources,” Collins said. “Our bipartisan legislation would help catalyze the development of this technology that holds great promise in the fight against climate change by supporting clean energy generation, including wind and solar.”

The bill aims to increase the affordability of energy storage technology by directing the Department of Energy (DOE) to pursue a strategic plan and implement cost targets. It also aims to accelerate testing and validation of energy storage systems through National Laboratories and requires coordination and alignment of the research efforts of DOE, National Laboratories, federal agencies, and end users.

The bill supports up to five demonstration projects and authorizes $60 million annually for the program from 2020 to 2024.

The program would focus on highly flexible power systems with a minimum duration of six hours and with a lifetime of at least 8,000 cycles of discharge at full output and 20 years of operation; long duration storage systems with power output of 10 to roughly 100 hours with a lifetime of at least 1,500 cycles and 20 years of operations; and seasonal storage systems that can store energy over several months and address seasonality concerns.

The program would be similar to DOE’s SunShot Initiative, which helped reduce the price of solar by approximately 75 percent in less than a decade.

“As a member of the Energy and Natural Resources Committee, advocating for the research and development of long-term energy storage has been a top priority,” Heinrich said. “I am proud to join Senator Collins to introduce the Better Energy Storage Technology Act and invest in reshaping the power industry. This bipartisan legislation offers federal agencies and national labs the opportunity to modernize our energy grid with advanced storage technologies that can provide days, even months, of capacity. With advances in solar and wind energy, New Mexico remains a leader in the charge towards a clean energy future. This bill adds the extra spark to boost New Mexico power grids – with the potential to do the same around the globe.”

As the Federal Energy Regulatory Commission (FERC) released an update to last year’s order on energy storage, MRS Energy & Sustainability today publishes a timely collection of papers that unpack the issue of energy storage in the Midwest and beyond.

Last February, FERC unanimously approved a landmark order in the fast-developing field of energy storage. FERC Order 841 directed grid operators across the US to develop market rules for energy storage to participate in the wholesale energy, capacity and ancillary services markets by treating storage as a generation resource.

The order was designed to enhance competition and to promote greater efficiency in the national electric wholesale market—and it effectively opened the floodgates for energy storage in wholesale markets. However, the FERC proposals have also stored up some problems for the future, which are examined in more detail in these three articles by leading experts from industry and academia in the Midwest.

A review by Ellen Anderson from the Energy Transition Lab at the University of Minnesota focuses on a story that no one else is telling: the conspicuous transformation of energy storage in the Midwest. Her article delves into the far-reaching implications of two energy storage summits recently convened in Minnesota.

She describes the role of energy storage in the Midwest as a case study, offering a detailed analysis of selected energy storage use cases.

Anderson said: “Although the Midwest storage market is relatively young, the MISO2 region is one of the world’s largest organized electric grids and will play a critical role for bringing energy storage to scale.”

As the FERC-regulated grid operator in the Midwest, MISO filed a plan for compliance with the Order 841 in December 2018, alongside other operators. This includes implementation details for integrating ESRs in the MISO market starting in 2020. This intervention makes this new collection of articles focusing on the Midwest particularly pertinent.

Legislation was introduced in both the House and Senate this week to encourage the development of energy storage systems in the United States. In the House, Congressman Bill Foster (D-IL) introduced the Better Energy Storage Technology (BEST) Act of 2019, co-sponsored by Congresswoman Jaime Herrera Beutler (R-WA), Congressman Sean Casten (D-IL), and Congressman Anthony Gonzalez (R-OH). Senators Susan Collins (R-ME), Martin Heinrich (D-NM), Cory Gardner (R-CO), Tina Smith (D-MN), Chris Coons (D-DE), Martha McSally (R-AZ) and Angus King (I-ME) introduced a companion BEST Act in the Senate.

The bipartisan legislation aims to support grid-scale energy storage R&D and improve the efficiency of the nation’s electric grid, while helping to align research efforts on energy storage technologies.

“Next generation energy storage devices will help enhance the efficiency and reliability of our electric grid, reduce energy costs, and promote the adoption of renewable resources,” said Senator Collins. “Our bipartisan legislation would help catalyze the development of this technology that holds great promise in the fight against climate change by supporting clean energy generation, including wind and solar.”

“If enacted, the BEST Act will authorize the Department of Energy to undertake new public-private partnerships for proving promising electrochemical, thermal, and physical storage technologies in actual electric grid operations. Doing so will ensure a fuller range of storage options is available to meet the needs of a 21st century electric system,” said Energy Storage Association CEO Kelly Speakes-Backman.

The BEST Act legislation aims to increase the affordability of this technology by directing the DOE to pursue a strategic plan and implement cost targets.

Thanks to “innovative business models” and the combination of PV with batteries, Japan’s “solar boom” is far from over, market expert Izumi Kaizuka of RTS PV has said.

Despite the imminent demise of higher level subsidy payments for solar energy fed into the grid, Japan’s consumers, businesses and utilities continue to demand clean energy solutions, while other factors including deregulation of the electricity market help bolster the business case for solar-plus-storage in particular.

Kaizuka met with Energy-Storage.news for an update on the world’s second-biggest annual market for solar by deployment, at last week’s Intersolar Europe / ees Europe show in Munich, Germany.

According to RTS’ figures, Japan installed 6.5GW of solar in 2018. The country, which introduced a feed-in tariff (FiT) in 2009 and then pushed those rates up even further to stimulate market growth in the wake of the Fukushima nuclear accident, as the Asian country, heavily dependent on imported fossil fuels as well as its dozens of now-shuttered nuclear generators, sought to establish its energy independence.

Choices made by consumers and policymakers will shape the future
Much has been written about that secondary boom, which began in the summer of 2012. At one point, it became clear that high FiT rates had attracted more would-be developers of large-scale projects than the grid could handle, while the cost of deploying multiple gigawatts of solar each year in a country where available land is scarce became a political issue.

At one point, it was thought that as much as 50GW of approved but still-not-built projects could lose their agreed feed-in tariff. It seems that now, a definitive measure is in place for the backlog to be cleared.

“Regarding ‘big’ projects, or those over 10kW anyway, METI (Ministry of Economy, Trade and Industry) has set a due date for these,” RTS PV’s Izumi Kaizuka said.

“They must secure grid connection agreements during 2020 and if they do so they will keep the level of feed-in tariff (FiT) applicable at the time they were approved. If they fail to secure this grid connection agreement, the FiT applicable to the electricity sold from their solar power plant will fall to ¥21 (US$0.19) per kWh sold. In 2020, it’s likely there will be a big rush to get these projects completed.”

The cost of energy storage is plummeting as performance is improving, and Congress is moving to help storage technologies continue to advance. Spurring innovation is far from all we need to do to address the climate crisis facing us, but it’s a necessary component and a start to development of comprehensive solutions.

After years in which many in Congress have done all they can to deny the science of climate change or avoid taking steps to address it, it’s reassuring to see lawmakers of both political parties acknowledging the facts and taking the first steps to grapple with it. Deploying technologies to save the surge in solar power on a sunny afternoon or wind power from a blustery night is one part of making our electric grid cleaner and greener.

Energy storage is increasingly recognized by both Republicans and Democrats as a necessary tool to unlock more clean energy like wind and solar, increase flexibility to meet changing patterns of electricity demand, provide essential grid services, and provide emergency power in times of disaster.

The Better Energy Storage Technology (BEST) Act, which was introduced by Senators Collins, Heinrich, Smith, Gardner, Coons, McSally, and King, adds to the growing set of energy storage bills introduced this Congress aimed at accelerating development and deployment of solutions to meet the emerging challenges of a cleaner electricity grid.

Customers procuring energy storage systems are emphasising their demand for energy, as well as power, as the market shifts to longer durations, a representative of Saft has said.

The European battery manufacturer has been active in the energy storage system (ESS) market since 2012, delivering around 100MW of operational projects to date. The recent launch at ees Europe of Saft’s new 20ft containerised NMC lithium-ion battery storage systems, available in 2.5MWh ‘blocks’, is a direct response to growing interest in energy storage for applications that go beyond storing and shifting short durations of energy to serve high-power applications, company energy storage business development and marketing manager Michael Lippert said.

“When we started to deliver our first containers, but at that time, the market was rather a paying for power [type of market] and so, therefore, our first generations of containers were more power-oriented, so for frequency regulation and for smoothing applications or ramp control,” Lippert told Energy-Storage.news at the show last week.

“Today, the energy storage market has very strongly shifted to more energy products. People are asking for two hours, four hours or maybe even more.”

According to Lippert, there are a variety of markets that are beginning to demand higher energy systems, although currently, the world’s maturing solar markets are showing the most interest. While storage systems by Saft and others were first deployed in those regions to deliver grid-balancing, through services such as frequency regulation to integrate renewable capacity onto networks, Saft’s customers find there is now a case for pairing renewables more closely with batteries.

Energy storage is increasingly finding its place in the sun. As a technology, it simply offers too many advantages and meets too many needs to be overlooked: it can ramp faster than a gas plant, it can stabilize voltage and frequency, and it can carry electrons from solar generation to deliver power after dark.

When you add to this the dramatic cost declines for lithium-ion batteries, the combination becomes unstoppable.

Regulators, utilities and state governments are beginning to understand this, and among other policies the Federal Energy Regulatory Commission’s Order 841 is opening wholesale markets to the participation of energy storage. Add in the tax advantages of coupling energy storage with solar under the Investment Tax Credit (ITC), and you have the perfect storm.

According to IHS Markit, the U.S. grid-tied energy storage market is poised to nearly double this year to 712 MW from 376 MW last year (note: This forecast does not include behind-the-meter energy storage). The company says that this will allow the United States to surpass South Korea, which was the world’s largest grid-tied energy storage market in 2017 and 2018.

And that is just the beginning. IHS expects nearly 5 GW of energy storage – 90% of which will be lithium-ion batteries – to be deployed in the United States from 2019 to 2023.

ITC drop down drives growth

The consultancy says that a big driver of the growth of energy storage deployments over the next four years will be batteries coupled with utility-scale solar, which it expects to comprise more than 40% of battery deployments, or roughly 2 GW.

This is made possible by multiple factors, including falling costs. But a main driver of the growth over this period will be the narrowing window of opportunity presented by the ITC, which drops down to 10% at the end of 2022 and can be used for paired solar + storage if the batteries are mostly charged using solar.

The full 30% ITC can only be claimed if projects start construction by the end of this year, however because of this provision the completion of many large-scale solar projects is expected to be stretched over the full four years, and it is likely that solar plus storage will follow this pattern.
