Mainstream brings together a unique depth of experience from all over the world. Our people have spent many decades working in the renewable industry as well as in the traditional utility sector. They have delivered over 2,500MW of significant infrastructure projects across 4 continents.
Global development expertise
We have over 450 years of combined experience among the team, in all the areas that are critical to project development. We have wind analysis experts, GS experts, engineering experts, permitting experts, environmental experts and grid experts. We also have construction expertise as well as operations and maintenance expertise.
Local knowledge
Project development is a local activity. To be successful you need to have Chilean people in Chile, South Africans in South Africa and so on. We have established development teams in all of our markets. These are local people, who know all there is to know about their market and they benefit from the global experience of our central team for support and advice.
Offshore excellence
We have a team of people based in London in our offshore centre of competency who are second to none in terms of a skill set for developing and consenting offshore wind farms. It’s a unique skill set, not because we say so, but because the market says so. We won the rights to develop the 4,000MW Hornsea project under an international competitive process and against some of the biggest utilities in the world, positioning us as the leading offshore wind developer in Europe.
