Jason McGray, head of development of Northampton-based Infinis, said the solar site will also feed straight into the grid and a “private wire connection” will run to Cranfield, part of the Brogborough Clean Energy Hub.
He said the land cannot be used for anything else due to the “long-term management of gas and leakage liquids”.
That gas is collected and fed through gas engines to generate a constant power.
He said: “It’s constant, it’s green energy but it’s predictable and manageable.
“Combined with that we’re now building solar so we’ve got the two sources of renewable energy both coming out of the same resource.”
In the event that too much power is generated, McGray said there is also room on site for battery storage.
He said: “We’ve got planning permission, so we can then store power temporarily until it’s needed on the grid.”
McGray predicts managing the gas will go on longer than the 35-year expected life of the solar farm.
