Industry Leader

Driving the global transition from the front

Pure-play pioneer. Technological innovator. Development standard-setter. Value-chain enabler. These are some of the reasons why we are an acknowledged leader in the renewable energy sector. But most importantly, we hold this position because we are a trusted partner.

It is through our effective engagement that we are helping local communities to share in the social and economic benefits of the energy transition.

We are helping countries to clear pathways to energy security and their net-zero targets, working with industry to gain early mover advantage in regional green supply chains, and supporting our own renewable energy sector to set the agenda on global climate action.

Our authoritative voice as a change-maker is helping to make tomorrow’s world truly sustainable.

Leading the global industry


We are an authoritative voice of renewable energy, and by amplifying it through industry bodies, innovation forums and special interest groups – around 65 at the current count – we are helping to set the policy agendas that will accelerate the energy transition.

Our people are doing this at every level, from their seats in more than 20 boardrooms and from positions on over 80 committees, taskforces and working groups.

On the international stage, we are one of the industry ‘Global Leaders’ shaping strategies – from COP manifestos to offshore wind in Japan – for the influential Global Wind Energy Council.

And reflecting our geographical reach, Mainstream representatives are sharing their expertise in areas as diverse as grid connectivity and project governance with some two dozen national and regional networks. Low profile work that will have big impact in the coming decade.

Equipping countries to become renewable energy leaders

We are working hand-in-hand with governments like Vietnam’s to help create environments that can rapidly build wind and solar energy capacity, and deliver sustainable opportunities for their communities, their industries and the environment.

 Shared vision with Vietnam

Building the UK’s offshore wind supply chains

Through our partnership with Siemens Financial Services, we were part of the UK’s biggest offshore wind supply chain success story. The partnership achieved great success in developing a sustainable offshore wind supply chain in the Humber region, following our development of the Hornsea zone – the biggest offshore wind farm in the world. The partnership enabled a competitive offshore-centred economy in the region, including Siemens Gamesa’s immensely successful blade manufacturing facility and service hub located at Green Port, Hull. Combined, these activities have created approximately 1,000 jobs.
