Li-ion battery system Europe's first to support wind farm

A megawatt-scale energy storage system will be delivered to help the Faroe Islands increase wind power usage in a commercial first for Europe, a battery company has said.

The 2.3MW ESS project will see the deployment of a lithium-ion (Li-ion) battery system operating in combination with a wind farm. The EES is expected to improve grid stability and harness the maximum potential of a new 12MW wind farm.

The move comes after Faroe Island officials decided to cut its dependence on oil and make use of wind and hydro instead to generate energy. It aims to increase the share of renewable generation from 38 per cent in 2011 to 75 per cent in 2020 as the country’s energy consumption continues to grow.

The 12MW farm was installed in 2014 and has increased the country’s wind share to 26 per cent of total electricity production with its 13 turbines.

Terji Nielsen, project manager energy supplier in the Faroe Islands SEV, said: “The environmental and economic futures of the Faroe Islands demand that we maximize the usage of all our available renewable energy resources. But it is equally vital that we maintain grid stability and reliability as the penetration of intermittent generation increases. ”

The Li-ion ESS will provide ramp control to smooth out sharp increases and decreases of power – created by other intermittent renewable energy resources – as well as frequency response and voltage control services.

Battery maker Saft has worked with wind turbine and energy converter specialist ENERCON on the project.
