Connecting small-scale energy storage units to the grid is economically viable and could also bring benefits to local communities, according to a new study.

The report – published by DNV GL and based on work by an industry-wide consortium that includes energy storage firm Alfen and Dutch flexibility aggregator Peeeks – outlines a decision-making framework to help grid operators and other stakeholders identify and optimise business models and revenue streams for community storage.

At present, distribution network operators (DNOs) need to install extra underground cables to help local distribution grids to cope with peak output from solar panels or wind turbines but this is an expensive and time consuming option.

The report explains how “community batteries” that store energy near to the panels and turbines can be a cheaper alternative.

‘Deployed today’

Ditlev Engel, Chief Executive of DNV GL’s Energy Business, said: “This is an important finding for the energy transition, showing that there is a fast and affordable solution for handling the intermittency of renewable energy sources that is also economically viable for everyone in the value chain.

“This latest study… shows that community batteries support the immediate deployment of decentralized energy resources.

“They can be applied today without waiting for costly and time-consuming grid expansion.”
