Ideal Power, the US company best known for its power conversion systems for energy storage, has announced two recent project orders totalling 1.6MW in northern Texas and in California. Just over 1MW of the company’s 30kW Stabiliti power conversion systems will be integrated into six solar-plus-storage systems at a California municipal school district. The 35 separate Stabiliti units will be installed with PV and battery energy storage at six installations.

Canadian utility Alectra Energy Solutions, which has over a million customers in Ontario, will offer large-scale energy storage to commercial and industrial operations in its service area, having formed a partnership with developer AMP. AMP Solar, which has developed over 520MW of energy assets to date, is headquartered in Ontario with offices in New York, Denver, New Delhi and Tokyo, executing and acquiring solar PV projects in the UK, Japan, Canada and elsewhere. The strategic agreement signed with Alectra appears to be AMP’s first publically announced foray into energy storage.

Aquion Energy, maker of energy storage batteries and whole systems based on a novel electrolyte with a chemical composition similar to saltwater, is back in business. The American company, which began production in 2014, went bust in March, offloading 80% of its workforce and sending its website offline. One British company, Solar PV Partners, which was selling Aquion Aqueous Hybrid Ion (AHI) batteries said Aquion had developed a “sustainable, clean and non-hazardous product”, also describing it as “cost-effective” and “scalable” compared to alternative storage technologies.

Despite a bill to create a rebate programme for energy storage systems purchased in California being dropped from a recent round of legislative decision-making, the state’s industry still has a “bright future”, commentators have said. Energy Storage Association vice president Matt Roberts and GTM Research analyst Brett Simon both told Energy-Storage.News this week that although Senate Bill 700 (SB 700) was taken off the voting agenda at a California Assembly meeting, where a ‘yes’ vote would’ve created a new policy pathway, California is set to continue its role as a leader in energy storage.

China-headquartered PV inverter manufacturer Sungrow has supplied a complete energy storage system to a commercial and industrial (C&I) solar-plus-storage project in the Bahamas. Unlike the company’s recent five-island microgrid project in the Maldives, the Bahamas system, at an unnamed customer’s site, is thought to be grid-connected. It provides behind-the-meter services such as load shifting and peak shaving and can also operate independently of the grid.

National Grid has reduced its forecasts for electricity storage capacity in the UK down to just 10.7GW by 2050 in the most ambitious scenario set out within its future projections for the energy sector. The latest Future Energy Scenarios (FES) document, published on Thursday, suggested the greatest level of storage would be deployed under its 'Consumer Power' scenario, which predicts a highly economic market driven by innovation over environmental concerns.

Business models used by Advanced Microgrid Solutions (AMS), including creating “Hybrid Electric Buildings” with energy storage, take the industry to a “new level”, VC investor Nancy Pfund has said. Investors including actor and activist Arnold Schwarzenegger, major Australian utility AGL, GE Ventures and Macquarie Capital participated in the successful raise of more than US$34 million in a Series B funding round, which AMS announced yesterday.

At least two global technology leaders could set up Gigafactories to manufacture lithium-ion cells in India in the next couple of years, according to the head of the India Energy Storage Alliance (IESA). This focus is being driven by opportunities in both stationary and electric vehicle (EV) applications in India, particularly with the government goal of making all vehicles electric by 2030.

A lack of clarity around India’s recently enforced Goods and Services Tax (GST) Bill has caused a PV tender delay in the state of Gujarat and prompted the nation’s energy storage alliance industry group to write a letter of appeal to the government. The India Energy Storage Alliance (IESA) has now sent a letter to energy minister Piyush Goyal asking for clarity over taxes on separate segments of cells and batteries.

AES Corporation has closed US$2 billion in finance for the 1.4GW Southland Repowering Project. The install in southern California encompasses 1,284MW of combined cycle gas capacity and 100MW of battery storage. The remaining US$350 million will be contributed as equity by AES. The company won a competitive tender in 2014 for a 20-year power purchase agreement (PPA) with utility firm Southern California Edison (SCE).

Expected since the beginning of this year, Massachusetts has confirmed that it will implement an “aspirational” 200MWh energy storage procurement target for electric distribution companies. The state’s Department of Energy Resources (DOER) had determined in late December 2016 that it would be a prudent move to set energy storage targets. However, the level of those targets remained undetermined until a communication from the Massachusetts DOER last week, signed by Massachusetts Governor Charlie Baker, Lt Governor Karyn Polito, secretary Matthew Beaton and commissioner Judith Judson.

Renewable energy company Energy Renaissance is constructing a 1GWh per annum lithium-ion battery storage manufacturing plant at Darwin, in the Northern Territory of Australia. The plant, named ‘Renaissance One’, will have seven production lines that are due to become operational in late 2018. The firm claims this will be the Southern Hemisphere’s first facility producing semi-solid state lithium-ion batteries, which it says are uniquely optimised for warm climates.

Hybrid systems combining the complementary aspects of more than one technology could “change the energy storage landscape”, with 2.1GW predicted for deployment in less than 10 years, according to a report from Navigant Research.

The US state of California’s Senate has approved a bill that would provide rebates to customers for the purchase of energy storage systems, bringing the legislation a step closer to introduction. The bill, SB 700, was introduced by Democratic Senator Scott Wiener, along with SB 71, which is a mandate for new buildings to include rooftop solar in their construction. Both passed the Senate by a 23-13 vote and are now to be passed over to the State Assembly for consideration.

The Australian state of Queensland has announced a 400MW renewable energy auction with 100MW ring-fenced for energy storage. The tender was part of a raft of announcements on Monday, including confirmation of a commitment to source 50% of its electricity from renewables by 2030. An Energy Security Taskforce has been established which will introduce the recommendations from a review of the country’s electricity sector. Queensland currently lags the progress of other Australian regions in terms of renewables deployment, but there have been multiple project announcements.

The UK is to become home to Europe’s largest battery flywheel system in a first for the country which will provide fast acting frequency response services and aid the integration of renewables. The €4 million (US$4.51 million) project is being brought forward to support the project which will be delivered by a consortium of engineers from the University of Sheffield, flywheel specialists Schwungrad Energie and Adaptive Balancing Power, and product supplier Freqcon.

Whilst most of the federal incentive buzz for energy storage surrounds California’s Self-Generation Incentive Programme (SGIP), new bills from Hawaii and Maryland provide insights on how state storage incentives are moving beyond the Golden State.

Swedish energy major Vattenfall has partnered with BMW Group to add battery storage capabilities at its largest onshore wind farm in Wales. The agreement will see the Pen y Cymoedd wind farm, which reached its full generation capacity earlier this month, equipped with up to 1,000 lithium-ion batteries each with a capacity of 33kWh and using the same battery technology as that used within the i3 car. 

Over €12 million (US$13.18 million) in funding will be provided to two European projects to examine and exploit synergies between the stationary energy storage and transport sectors, through the EU’s Connecting Europe Facility (CEF) funding instrument.

Tesla has announced the first programme to aggregate the capabilities of hundreds of its residential and commercial stationary storage systems in a partnership with Vermont utility Green Mountain Power. The pair will bundle together up to 2,000 of Tesla’s residential Powerwall and commercial and industrial (C&I) Powerpack systems to create a “single resource of shared energy”, Tesla said, calling it the “next step in tapping the potential” of energy storage systems in the field.

India’s biggest utility, NTPC (National Thermal Power Corporation) is seeking bidders to add a 6MW / 24MWh battery energy storage system (BESS) to a 17MW PV plant in Manglutan, South Andaman. Indian home minister Rajnath Singh laid the foundation stone for the PV project in early April. Our sister site PV Tech reported at the time that there would also be a separately held tender for energy storage to support the solar farm, which is located on the remote Andaman Islands, several hundred kilometres off the Eastern coast of mainland India.

Multinational energy company Engie Group has contracted NEC Energy Solutions and NEC Chile to provide a 2MW / 2MWh energy storage system to its subsidiary Engie Energia Chile in Latin America. The project will be NEC Chile’s first smart energy project and was awarded to the company last week through a competitive solicitation process, it was announced on Tuesday. While NEC Energy Solutions has executed two other energy storage projects in Chile already, totalling 32MW, it will be Engie’s first energy storage system in the country and follows news from last month that the France-headquartered group’s Brazil operations will be trialling the use of a grid-scale zinc hybrid cathode battery system from Eos.
