Irish energy storage

The VRB Energy Storage System being sold to Tapbury Management Limited for Phase II of the Sorne Hill Wind Farm in Ireland has been increased in size to a 2MW x 6hr system.

The VRB Energy Storage System (VRB-ESS) being sold to Tapbury Management Limited for Phase II of the Sorne Hill Wind Farm in

has been increased in size to a 2MW x 6hr system. The deal confirms Sorne Hill as

’s largest energy storage project.

The value of this contract to VRB Power has increased from $6.3m to approximately $9.4m.

The increase in size of the contract follows publication of an independent feasibility study on the implementation of the VRB-ESS at Sorne Hill, which was jointly commissioned by Sustainable Energy Ireland (SEI) and Tapbury Management Limited.

The study anticipates internal rates of return to purchasers of VRB Energy Storage Systems in Ireland of up to 17.5%, increasing the economic appeal of wind power in Ireland and potentially across Europe and beyond.

The study also concluded that the optimum size of the system is 2MW of power with six hours of storage and the ability to provide 3MW of pulse power for 10-minute periods every hour in order to deal with short-term volatility in wind generation.
