Great British Energy (GBE) says its investments aim to support at least 10,000 jobs over the next five years, with a focus on areas historically dependent on oil and gas.
The publicly-owned body, set up by the UK government, has been told by ministers to invest billions to accelerate the transition to green energy.
It says it wants the transition to be seen as "the great economic opportunity of a lifetime" rather than a financial burden.
But there are concerns that the rate of job creation may struggle to keep pace with the number of roles being lost in fossil fuel sectors.
