Renewable energy offers energy intensive users locked-in costs for electricity and reduced risk to carbon exposure.


Mainstream is the leading renewable energy development partner for utilities. We deliver fully operational wind and solar plant to utilities.

Our business model works by taking a wind or solar plant through all the stages of development until onshore we’ve got an operational wind farm or solar plant or, offshore in the ready-to-build stage. Then we sell the plant to their natural owners, such as utilities.

Development is inherently a risky process. But we have a deep understanding of these risks and we’ve a track record in handling them, managing them and delivering the end result.

So we develop and build the plant, then we pass the operating plant on to the utility at a price that is acceptable to both of us.
