Germany’s RWE has agreed a five-year power purchase agreement (PPA) to supply renewable electricity from its Camster onshore wind farm in Scotland to UK utility Thames Water, the company said.
The agreement will run from December 2025 to 2030 and is expected to provide around 132 gigawatt hours (GWh) of electricity each year, covering up to 15% of Thames Water’s essential operational needs, RWE said.
Electricity will be supplied from the 50-megawatt Camster wind farm in Caithness, northern Scotland. The project, which comprises 25 turbines, was commissioned in 2012.
“Water is the elixir of life and access to clean drinking water is essential,” said Olaf Lubenow, head of commodity solutions UK, north and south Europe at RWE Supply & Trading. “We are therefore delighted to support Thames Water in its important societal role by providing green electricity.”
Thames Water said the agreement supports its efforts to cut emissions and manage long-term energy costs, which represent a significant share of its operating expenses.
“Our purpose is to deliver life’s essential service, so our customers, communities and the environment can thrive,” said Xiang Cheng, head of energy and carbon at Thames Water. “We’re committed to reducing our greenhouse gas emissions and transforming the way we generate, purchase, and use energy.”
Cheng added that PPAs allow the utility to secure renewable electricity at a fixed cost over an extended period. “This agreement will help us manage future planning for energy costs,” he said.
