Batteries in private households will be now able to perform the “same tasks as a conventional power plant”, across the whole of Germany, the CEO of Sonnen has said, following a ruling that opens up grid services markets to the company’s devices. Sonnen last week announced that it has obtained pre-qualification to enter Germany’s Primary Control Reserve market by grid operator TenneT for its battery energy storage units installed across the country. Primary Control Reserve is a form of frequency regulation, keeping the grid to within acceptable boundaries of its optimum 50Hz operating frequency.
The US government has been urged to recognise the “critical role” energy storage can play in making the grid cleaner and able to accept more renewable energy, by increasing the eligibility of batteries and other technologies to receive the Investment Tax Credit (ITC). The ITC is applicable to purchases of solar energy equipment in the US and applies about a 30% rebate or discount for buyers. In recent years the policy scheme has been adjusted to include energy storage but for a long time, storage systems could only receive the Federal subsidy if installed at the same time as solar equipment.
Arsenal football club’s Emirates Stadium in London, England, has become home to what could be the first behind-the-meter battery of its size aimed at wholesale energy trading over frequency response. The 2MW/2.5MWh system unveiled today is the first battery storage system to be installed at a UK football club’s stadium following three years of development between the club, developer Pivot Power and investment company Downing LLP.
NantEnergy has acquired Sharp Electronics Corporation's US-based energy systems and services business, which develops and delivers energy management systems across the country.

Mansfield will continue with NantEnergy as vice president, system solutions. Among the products that NantEnergy will acquire includes the SmartStorage behind-the-meter energy storage system.
Transmission system operators in the US have begun making their moves to accommodate energy storage into their wholesale markets, with New England ISO and Southwest Power Pool both making filings in the past month. In February the US’ main regulator the Federal Energy Regulatory Commission (FERC), issued FERC Order 841, instructing the US’ six regional electricity transmission organisations to reconfigure their wholesale markets to allow energy storage to participate. The ISOs and RTOs have about a year to respond in full.
Scotland’s first utility-scale battery storage facility has been officially opened today, having begun delivering sub-second balancing services to National Grid at the end of June under a bespoke agreement secured before the hotly contested Enhanced Frequency Response (EFR) auction of 2016. The 20MW Broxburn Energy Storage facility was built by RES, which had sold the project to The Renewables Infrastructure Group (TRIG) in August last year for £20 million. It was the first project to have been acquired by TRIG and RES’ fourth in the UK, with the company now managing the site.
“The innovation of California within the energy sector is welcomed by the storage industry as we stand on the precipice of realizing our own goal of 35 GW of new storage deployed by 2025,” said Kelly Speakes-Backman, CEO of the Energy Storage Association in the US. “As an enabling technology with a multitude of applications, the added flexibility that storage provides to the electric grid will prove crucial to achieving the goals of SB100 in a cost-effective manner while maintaining grid reliability. Storage resources can be deployed to optimize existing renewable energy resources and to integrate additional ones, serving as a multiplier of the greenhouse gas reductions made possible by ambitious clean energy policies like California’s,” she said.
Following news of SB100, legislation that would set California on a path to 100% renewables by 2045, the state is also on the brink of setting up a rebate programme for energy storage equipment sales. Senate Bill 700 (SB700), authored by Senator Scott Wiener, would extend the state’s feted SGIP (Self-generation incentive programme) policy to 2024 and make more provisions to include energy storage. SGIP supports the deployment of solar, wind turbines, microturbines, fuel cells, energy storage and other distributed energy technologies by utility customers.
A household just outside Berlin has become the recipient of the 100,000th grid-connected residential battery energy storage system in Germany.

Bareiß hailed the event as an “important milestone” that Germany has reached in its energy transition – referred to domestically as the Energiewende.
Following news yesterday of the first grid-scale solar-plus-storage system on the Hawaiian island of Molokai, two more modestly-sized projects show the potential diversity of applications for energy storage in the US state. Energy-Storage.news just reported that the Hawaii Public Utilities Commission had approved a 22-year power purchase agreement (PPA) deal for the project on the island of Molokai, which would pair 4.88MW of solar with a 3MW / 15MWh lithium battery system.
Elon Musk has confirmed that he wants to take Tesla private. In classic Musk form, he had earlier tweeted that an offer of US$420 per share was in the works. It would be more conventional for such an announcement to be published through an official filing. He confirmed the offer later in the day in a company statement.
Minnesota electric cooperative Connexus Energy has confirmed recent press reports that it is building 15MW / 30MWh of battery energy storage, while another not-for-profit, Vermont Electric Cooperative, will build a 1.9MW / 5.3MWh system in its service area. Connexus is part of Great River Energy, an electric transmission and generation cooperative and the second largest utility in Minnesota. Connexus serves about 130,000 residential and commercial properties in its service area. It issued a statement yesterday stating that the “innovative” solar-plus-storage project is now under construction.

India’s Goods and Services Tax (GST), a single tax applicable across the whole of the country, will be lowered for lithium-ion batteries by 10% in a move which has been welcomed by the India Energy Storage Alliance (IESA). All goods and services are taxable under the law, which was introduced in 2017. Along with a wide range of other changes, the GST rates on lithium-ion batteries has dropped from 28% to just 18%. In related news, fuel cell vehicles will see their GST reduced from 28% to 12%.
Lithium and sodium sulfur batteries will be used for the first time in new territories, after NEC ES and NGK inked deals to deliver projects to an island archipelago in Brazil and in Dubai respectively. Integrated electricity company Neoenergia, active in distribution, generation and other parts of the supply chain in Brazil, was requested by ANEEL (National Electric Energy Agency) in 2017 to help find sustainable ways to wean Fernando de Noronha, 350km off the country’s north-eastern coast, from a heavy dependence on expensive and polluting diesel generators.
Australia’s energy and environment minister has hailed the country’s accelerating residential energy storage sales as a report has emerged from Chief Scientist Dr Alan Finkel which says the “financial equation is straightforward” for adding batteries to home PV systems. Finkel’s office produced reports during 2017 which advised the government on the power market, opportunities and challenges for renewables and decarbonisation and the role of clean energy technologies in boosting the resiliency of energy networks across Australia. At the tail end of the year, he also published a report on the “transformative role” of energy storage.

The national Ministry of Energy has appointed the Dutch-headquartered group to conduct the study, which will be delivered for the Renewable Energy General Directorate at the Ministry. DNV GL aims to inform the directorate of best practice solutions for including energy storage in forthcoming large-scale solar project tenders.
A community microgrid in Chicago will be supplied with lithium-ion battery storage from aerospace and defence giant Lockheed Martin, allowing it to be ‘islanded’ from the local grid network. Bronzeville, in the South Side of Chicago, is hosting a community microgrid built by utility Commonwealth Edison (ComEd). It is being developed with the help of a US$5 million grant from the US Department of Energy (DOE) and is acting as a demonstration of the technology and its uses.
French utility Engie and German energy storage firm sonnen have signed a strategtic partnership to offer a package of solar and energy storage to households in France. The ‘My Power’ package is already available and Engie has identified 3 million customers in France living in detached houses that are conducive to using the solar-storage combination. Moreover, customers in southern France could power close to 100% (up to 95%) of their electricity needs through the package in the summer months between May and September, with northern customers able to generate around two thirds of their power demand. Sonnen spokesman Mathias Bloch emailed Energy-Storage.News this week to confirm reports of the deal which had appeared in various news outlets.
New Jersey is the latest US state to set itself targets for the deployment of energy storage, with newly passed legislation calling for 600MW of the technology within three years. A bill, S2314/A3723, passed last week as one of three sustainability and low carbon measures for the state going forward, calls on the New Jersey Public Utilities Board to analyse the costs and potential benefits of energy storage as well as making revisions for community solar, energy efficiency, peak demand reduction and solar renewable energy certificate programmes.
