A SCOTS company behind pumped storage hydro schemes has praised the latest figures for onshore wind power generation, but claimed a “green ceiling” on renewable generation will have to be addressed to ensure that net-zero targets are met. The ILI Group said the latest figures for the first six months of this year showed Scotland generated enough electricity through onshore wind power to supply 4.47 million homes – double the number of households in Scotland. “However, they can also be misleading since there is currently a ‘green ceiling’ to the amount of renewable generation that the power network can accommodate. As new renewable generation goes online and older coal, gas and nuclear plants contribute less, this leaves us increasingly dependent on intermittent renewable power that cannot be scheduled to meet demand or lack of it, to fill this gap. The missing link is energy storage on a scale that was unimaginable only 10 years ago.” Wilson added: “Our own company’s 2GW of planned pumped storage hydro schemes in Scotland can go a long towards filling this gap and along with hydrogen and battery technologies will help ensure the transition to net-zero electricity generation.

ENERGY giant Drax has underlined its willingness to invest heavily in developing the portfolio it acquired in Scotland through a £700 million deal. The head of the company’s generating arm, Andy Koss, said Drax was very pleased with the performance of the assets concerned. These include a giant reservoir-based pumped storage system in Argyll, the Lanark and Galloway hydro-electric facilities on rivers in South West Scotland, and a biomass fuel plant near Glasgow. He said the company sees enough potential in the Cruachan pumped storage facility for it to be prepared to make the massive investment required to achieve a big increase in capacity at the plant, with the right official support. The plans under consideration include one which would involve developing a new reservoir and turbine hall. The cost would probably run into hundreds of millions of pounds.
