Claims that Nick Clegg and George Osbourne are divided over their views on green energy are expected to be denied by the deputy prime minister.
Later today (August 6th), Mr Clegg will aim to reassure business leaders that the coalition is united in its long-term plans for the renewable sector.
He will say: "Consistency from government, no surprises, no rabbits out of hats. We set out what we're going to do – then we do it. It sounds obvious, but you all know governments don't always act like that."
The announcement follows continued disputes over the Conservative backbench's refusal to back Lords reform.
However, Mr Clegg will tell a green business summit that £100 million is to be invested in small-scale, non-domestic energy saving.
The Liberal leader is expected to claim the coalition government is "unreservedly committed" to helping the low-carbon sector thrive.
