Tucson Electric Power (TEP), a utility in Southern Arizona with around 420,000 customers, has received approval to build two 10MW energy storage systems, including one co-located with solar, from the state’s regulator.

As more and more Australians look to energy storage solutions, a set of installation guidelines from the Clean Energy Council (CEC) has been released for industry and consumers which will be mandatory for installers accredited by CEC schemes by October.

An influential German think tank and a national energy storage industry association have both said that long-term solutions need to be found for residential solar-plus-storage owners’ part-time reliance on the grid.

SolarReserve eyes 1GW solar thermal storage deal in China, first bi-directional inverter launched and proposed Australian pumped hydro site up capacity to 450MW.

A utility in California is investigating how energy storage technology for keeping food and other goods refrigerated could help counter the challenge posed by the famous “duck curve” of PV energy supply and demand.

All the news, views and updates from the Energy Storage Summit at Twickenham Stadium, London.

This week, at the Energy Storage Summit in London on Thursday, Solar Media brings together a broad range of stakeholders as the country goes through some defining moments in infrastructure and energy policy. Here are some interesting recent developments in the space – and who you might expect to meet if you make it to Twickenham Stadium.

The trial of a 6MW/10MWh ‘Big Battery’ has proven energy storage can help Britain’s electricity network, but the next crucial phase is to assess the business case, the grid operator which commissioned it has said.

Utility-scale solar projects in a region of Japan affected by fears of grid capacity constraints have been supplied with energy storage, aimed at mitigating the potential effects of output curtailment.

While the effectiveness of flow batteries in islanded situations is quickly being recognised, on the grid, the cost of providing that storage is still seen as something of an inhibitor to uptake. Andy Colthorpe spoke with the RedT CEO, Scott McGregor, to get his views on how flow batteries can thrive – and why lithium-ion is not the enemy.
