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.
