The firm worked with its sister company Eelpower Limited to deliver the two schemes, each with a capacity of more 1.2MWh using batteries supplied by China’s BYD and installed by UK cleantech firm Anesco.
The batteries will be remotely controlled using UK company Limejump’s virtual power plant technology.
The projects are already delivering on a two year, Firm Frequency Response service contract with UK transmission firm National Grid. The systems could also potentially relieve costs during TRIAD days — part of a charge-setting process that takes readings from the three half-hours of highest demand on Great Britain’s electricity transmission system between November and February.
When performing grid-balancing services, 60%-70% of the battery’s consumption will be provided by hydropower with the rest coming from the grid.
The low-head river hydro projects have been deployed at: Thrybergh, on the Rover Don near Rotherham and at Knottingley, on the River Aire near Wakefield.
Barn Energy plans to install a third battery storage unit at its 500kW Kirkthorpe hydro scheme on the River Calder.
When not performing FFR or TRIAD services, the batteries will be used for load shifting and for trading to maximize the revenues at each site.
Mark Simon, chief executive of Barn Energy and Eelpower Limited told ESJB: “We have deployed the system because we have a lot of experience with battery installations on a solar farm and have seen that they make a significant impression on ones ability to export energy.
“The only difference with a hydro plant is it is more expensive to build and so the returns are more modest.”
Australian utility Alinta Energy announced on April 12 it had switched on the country’s biggest industrial application lithium ion battery at its Newman Power Station in the Pilbara region of Western Australia. The 30MW/11.4MWh battery is capable of operating as a stand-alone system or can supply power if one or all of the station’s read more
Wind power company Siemens Gamesa Renewable Energy — created last April from a merger between Gamesa Corporación Tecnológica and Siemens Wind Power — has been commissioned to build a wind farm in Australia incorporating a 20MW/34MWh lithium-ion battery, the company announced on April 10. The company has been awarded an engineering, procurement and construction read more
Kraftwerksbatterie Heilbronn, the joint venture between German firms Bosch and utility EnBw, announced on April 13 it had commissioned a 5MW/5MWh lithium ion energy storage system for primary control reserve at EnBw’s coal-fired power plant in Heilbronn, Germany. The ESS consists of 768 lithium ion modules that allow the transmission grid operator to balance read more
Japanese firms Benex Corp and Sumitomo announced on April 17 they had launched a project using second-life lithium ion electric vehicle batteries to power Benex’s plant in Isahaya, Japan. The stationary energy storage system project combines renewable energy, end-of-life batteries and electric vehicles to demonstrate the technology as Japan moves to a low carbonized read more
Energy storage is at the heart of a bill passed by the New Jersey House and Senate on April 12 that will require utilities in the US state to generate at least half of its power from renewables by 2030. The bill A3723 compels the state to investigate how energy storage will affect the read more
