A large-scale storage system co-located at a German solar farm by the PV plant’s developer Belectric, has been given the green light to operate in the grid-balancing frequency response market.

France’s government has launched a tender for 50MW of projects combining solar power with energy storage systems on Corsica and its overseas islands territories.

Tesla’s grand entrance to the stationary storage market has been (largely) welcomed but question marks remain over the company’s business model. Andy Colthorpe gauges the latest reaction and explores the options facing Elon Musk.

Tesla reported losses of around US$0.36 per share in its quarterly earnings announcement yesterday, despite a flurry of activity around its stationary storage launch last week – yet the company still outperformed the expectations of the investment community.

Ecotricity, a UK-based supplier of renewable and clean energy, will trial a home energy storage box later this year.

More details have emerged on inverters for Tesla’s new home battery system, to be made by Fronius and SolarEdge, while the EV-maker’s energy storage will be installed at demonstration and commercial projects for US utility Edison International.

Tesla’s Powerwall home energy storage system will join the US market at a “remarkably low price”, according to one analyst PV Tech has spoken to following the announcement from Silicon Valley last night.

Prices for Tesla’s stationary storage systems for homes, businesses and off-grid communities, to be packaged and sold in partnership with SolarCity, will begin at US$3,000, thought to be as little as a third of the price of comparable products previously available on the market.

A Japanese utility which last year temporarily suspended new grid applications for large-scale solar, sparking a wave of similar suspensions by other utilities, will install a huge battery project aimed at integrating a higher capacity of renewable energy generation.

The remote Faroe Islands in northern Europe are to benefit from a major energy storage system, which as well as helping integrate renewable energy sources, will also operate on a commercial basis providing grid balancing and other ancillary services.
