The UK’s second subsidy-free solar farm, and the first by a local authority using battery storage, has been completed by West Sussex County Council in a project that ticked “every box” and will generate significant income over the next 25 years.

Uninterruptible power supply (UPS) provider Vertiv is to use energy flexibility specialist Upside Energy’s cloud-based platform to enable its customers to provide unutilised energy to the UK electricity grid.

‘Energy resilient infrastructure upgrades’ planned for a US military facility will involve the deployment of 20MW of solar PV, 4MW / 8MWh of battery storage and 4MW of gas-fired backup generation in a project worth US$133.5 million.

As Japan’s heavily regulated energy markets continue a process of liberalisation and supposedly increasing consumer choices, utility TEPCO has launched a smart electricity tariff enabled by the capabilities of residential battery storage.

South Africa’s state-owned utility Eskom has unveiled its Distributed Battery Storage Programme at an event this week, committing to solar-plus-storage and energy storage projects totalling 1400MWh.

News in brief from around the world of energy storage.

Australia is to trial using solar and wind power to produce hydrogen via electrolysis, with the hydrogen then being used for long-term energy storage in the Sydney gas network.

The renewables investment community “needs to come to grips” with merchant risk after a decade of being “spoiled” by government-backed subsidies for wind and solar.

It’s likely a strong indication of the way the world is adopting renewable energy rapidly that just under a month ago, one of the best-established trade shows for solar in the US featured what seemed like almost as much space dedicated to national and international energy storage companies and technologies, as it did for solar.

The UK’s government has shied away from supporting large volumes of solar and other distributed energy technologies through subsidies, but commercial and industrial energy storage and solar-plus-storage could be a huge market opportunity in Britain and abroad.
