Octopus Energy has said it aims to invest £2 billion in UK clean energy projects between now and 2030.

The company said it has just kicked off the investment drive by buying four solar farms which are being built in Bristol, Essex, Yorkshire and Wiltshire this year and next.

When they start producing power, in the next two years, the four farms will produce enough power for about 80,000 homes.

Meanwhile, the company said it also recently upped its stake in Exagen, a firm which builds solar farms and energy storage sites.

Octopus, the UK’s largest retail energy supplier, invests in power projects via its energy generation business, which in turn manages a number of investment funds.

The £2 billion figure includes these initial deals, but also represents a pipeline of future investments it hopes to make by the end of the decade.

It comes amid Government plans to invest more than £8 billion in renewable energy via its state-owned energy investment company, GB Energy, in the next five years.

Labour has said it wants to make Britain a “clean energy superpower”, and also recently scrapped a de facto ban on onshore wind farms in the planning system.

Zoisa North-Bond, CEO of Octopus Energy Generation, said the investment “will help boost our energy security and pave the way for a more affordable energy future”.

“Solar and onshore wind are among the cheapest energy sources available. By building closer to demand, we can maximise green electricity when it’s abundant and lower bills for customers nationwide.”

Elsewhere, ScottishPower’s boss recently told PA news agency that the company has a UK spending programme of £12 billion in the years to 2028.

Keith Anderson said he would “love to double that” if Labour policies designed to speed up development of clean energy projects bear fruit.

Centrica, meanwhile, said earlier this year that it is considering pumping cash into the construction of the Sizewell C nuclear power plant in Suffolk, among other investments.
