Virtual Power Plant

With its sonnenVPP, German battery company Sonnen wants to improve the efficiency of virtual power plants which it says can offer primary balancing energy from houses with solar and storage and can operate up to 90% more cost-effectively.

The German storage system provider intends to use its ‘Sonnen-Flat’ payment package to help customers benefit from the proceeds of its virtual power plant.

With hundreds of homes and businesses having received solar-plus-storage systems and monitoring equipment, an algorithm is managing a market for flexibility and capacity in Cornwall. Homeowners with storage can place bids to sell energy from their systems to the distribution system owner on an intraday basis.

The company says its network is the largest fleet of batteries under virtual power plant management worldwide.

The energy services firm will use software from California’s AutoGrid to develop a VPP which will draw on PV generation, energy storage and demand response technology. ENERES wants businesses to come on board and burnish their renewables credentials.

Norwegian hydropower company Statkraft has revealed more details of its solar-storage-wind-gas network. Previously announced plans to potentially double capacity this summer were not mentioned in the update.

The Japanese government has issued a policy to reduce 80% of vehicle-related emissions, but high-power charging facilities for e-buses should also be aligned with distributed PV generation. Kyocera is now optimizing its virtual power plant technologies for this use case.

At the Smarter E Europe, held in Munich this month, pv magazine hosted another Future PV Roundtable to discuss the possibilities of subsidy free solar projects. In all market segments solutions are at hand and representatives across the industry shared their insights with us.

The energy transition does not only change electricity generation, but ideally also how we consume. Electricity markets in Europe, however, must deal with legacy regulations that fail to incentivize ideal consumption patterns to reduce curtailment and make the best possible use of the renewable energy assets we have. The result is towering bills for ancillary services, that could easily be avoided with a few regulatory tweaks and virtual power plants.

Australia’s federal Labor party has pledged to roll out PV generation and batteries at schools across the nation, and to create VPPs supporting up to 365 MW of capacity.
