Installation plans for a 300MW pumped-storage hydroelectricity (PSH) scheme in Scotland were announced today (24 August), in the same week that the Scottish Energy Minister claimed that the sector was “at a crossroads” and required substantial UK Government support. The £200m PSH electricity storage facility on the Isle of Lewis will significantly increase (from 40% to 80%) the use of the Western Isles cable being installed by the National Grid to export and import electricity generated from renewable energy sources on the islands. Generating enough electricity to power more than 200,000 homes, the innovative Eishken Limited-operated scheme will utilise the sea as the lower reservoir from which water will be pumped uphill to a second reservoir at a higher reservoir. Eishken expects that this method will create a much lower environmental impact than would be caused by creating a second reservoir. The company’s owner Nick Oppenheim said: “There are very few PSH schemes throughout the UK and what we are proposing is particularly innovative given the use of the sea as the lower reservoir. “This scheme will not only materially enhance the benefits to be derived from the Western Isles link but will make a material difference in the supply of energy to the mainland. It will also be a key element in the Scotland’s renewable energy armoury.” The project forms part of the already consented 162MW Muaitheabhal Wind Farm on the Isle of Lewis, and will share any financial surplus with the local community following a three to five-year construction period.

Grid-scale electricity storage will move closer to commercial reality on Friday when the U.K.’s grid operator offers contracts to companies to help balance the network, a key measure needed to help balance increasing supply from renewables. National Grid Plc will announce the winners of a bidding round for as much as 200 megawatts of storage capacity, which is about the size of a small power plant. It’s likely to be the storage industry’s biggest award this year in global market expected to install $5.1 billion of equipment in 2020, according to Bloomberg New Energy Finance. Storage plays a key role in the greening of utilities’ networks by allowing grid managers to handle higher volumes of intermittent power from the wind and sun. The program is a “major boost for energy storage,”’ said Logan Goldie-Scot, analyst for BNEF in London. “Previously, activity had for the most part been limited to standalone demonstration projects” funded by the U.K. power regulator, Ofgem.
