Anesco and Limejump to build 185 MW UK storage portfolio


British renewable energy developer Anesco is planning to build an energy storage portfolio of 185 MW in the U.K. by the end of next year.

The project will be developed in collaboration with aggregated battery network operator Limejump, and once completed will be the U.K.’s largest portfolio of energy storage.

Anesco confirmed that the capacity will play a significant role in balancing the U.K. power grid through the capacity market, joining Limejump’s Virtual Power Plant portfolio to deliver sub-second dynamic frequency response that will support the National Grid’s supply and demand requirements.

The 185 MW storage portfolio is now planned for entry into the U.K. capacity market this summer (August), while the physical systems will be finalized by the end of 2018.

This announcement follows the news that Anesco has raised its active storage portfolio to 18.9 MW having recently connected its 20th utility scale battery unit.

“As well as aiding grid stability, energy storage can help maximize the use of renewable power being generated, while breeding a more resilient local grid,” said Anesco executive chairman Steve Shine. “It’s an exciting time for the sector and we predict momentum will continue to grow, as more and more generators look to benefit from the technology.”

Limejump’s virtual power plant oversees the largest portfolio of energy storage capacity in the country, combining quick energy response with the flexibility of both distributed generators and commercial battery assets. This platform enables storage providers to participate in the U.K.’s only dynamic frequency response contracts.

“Limejump is proud to be commercially operating the Anesco projects within our virtual power plant, providing them with access to the full breadth of the market opportunities and enabling more distributed generators and commercial assets to participate in grid balancing schemes,” said Limejump chief executive Erik Nygard. “The key to bringing more storage online will be to optimize the revenue that can be earned by generators and developers, from securing a good price for power exported on to the grid, to participation in the full range of revenue-generating schemes such as the capacity market.”

Throughout the U.K., Anesco has a solar PV portfolio of 480 MW spread across 101 sites, the company confirmed.
