Future arrangements between the UK and EU energy markets should maximise the benefits of interconnection with the bloc's countries.
Under the Brexit agreement, the UK and the EU have agreed a framework for future electricity trading.
The new model includes guarantees for open and fair competition, including on safety standards for offshore, and the production of renewable energy, according to the EU.
The UK Government has said the agreed model of trading will take time to develop and will not be in place for 1 January 2021.
Previously developed and communicated alternative arrangements will need to be implemented in the interim, it said.
RenewableUK director of strategic communications Luke Clark (pictured) said: "We welcome the announcement of a Brexit deal as we hope it will provide certainty for investors and stability for hundreds of companies developing and operating vital renewable energy projects throughout the UK.
"It's important that our future arrangements with the EU’s energy market allow us to trade power in a way that maximises the benefits of the interconnection with EU countries, so we can export our surplus power and import flexibly to support our energy system when necessary.
"We'll need to study the text of the agreement in detail and there are several key points we'll be looking out for, but the agreement of a free trade deal on goods will help the British manufacturers exporting renewable technology to EU countries."
