The software platform now incorporates data from a SolarEdge inverter, meaning clients can run residential storage dispatch simulations and work out the optimum schedule for operations.

A salmon farm in Norway will become more environmentally friendly with the addition of a Tesvolt-supplied battery energy storage system, reducing the run time of diesel generators onsite by up to 18 hours a day, saving on costs and working time spent on maintenance.

The business models and technologies underpinning the development of stationary energy storage markets are evolving rapidly. Dr. Kai-Philipp Kairies, Jan Figgener and David Haberschusz of RWTH Aachen University look at some of the key trends driving the sector forwards, in a paper which first appeared in PV Tech Power’s Energy Storage Special Report 2019.

While lithium-ion enjoys the most media and customer interest at the moment, alternative technologies for storing energy could become competitive – if investors are willing to take them on to the extent that manufacturing efforts can be greatly scaled up.

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.

Battery storage technology costs will have to fall by a further 30% before projects in the UK are feasible without lucrative frequency response revenues, a leading investor has said.

The number of installed stationary battery energy storage systems (BESS) is growing significantly. According to recent estimates, today’s annual global market volume of about US$1 billion is expected to increase more than twentyfold in less than 10 years, reaching a staggering US$20–25billion by 2024. Florian Mayr of Apricum Consulting looks at this growth in the context of specific use cases for storage in two of its most advanced regional markets, the US and Germany.

Reports that a grid operator in France has found battery-based energy storage “too costly” to be used to integrate renewable energy have been criticised by a spokesman for energy storage developer Younicos.
