Commercial energy supplier SmartestEnergy has signed a power purchase agreement (PPA) with European solar developer Greentech for a solar PV project in Kent.
The two firms inked a 15-year pre-construction Contracts for Difference (CfD) PPA for the 26MW Chalkpit Solar Farm in Guston, Kent. The deal covers the pre- and post-commissioning phases of the 25 hectare project’s lifetime, which SmartestEnergy said provides “revenue certainty throughout its lifecycle”.
SmartestEnergy won the contract through a competitive bidding process, which will now see it buy the power from Greentech’s first renewable energy asset in the UK.
The company said that the deal “marks…a foundation for future collaboration” and speaks to the “continued attractiveness” of the UK renewable energy market, largely on the back of the CfD scheme which provides investment and revenue security for new projects.
“Projects like Chalkpit demonstrate the strength and attractiveness of the UK’s renewable energy market, and highlight the important role offtakers play in helping developers bring renewable generation to the market,” said James Clark, business development manager at SmartestEnergy.

Yaw Ofori, managing director UK at Germany-based Greentech, said that Chalkpit “marks the starting point for our long-term investment strategy in the UK, which we see as a significant energy market to have a stake in, and contributing to the decarbonisation of the UK grid.”
Greentech said it would be looking to develop more CfD-backed projects.
The CfD has proved a major driver of UK renewables, particularly solar PV. Solar Power Portal heard earlier this year that it is a “very attractive” incentive which was providing optimism for the market. The government recently announced that the strike price for the upcoming auction round, Allocation Round 8 (AR8), will stay the same as they were in AR7 at £75/MWh.
