What we do

Project delivery

Bringing renewable energy assets to life

One of the biggest challenges of the energy transition lies not in access to capital, but in creating a pipeline of investible projects.

That's why we're developing assets and delivering innovative capital structuring solutions to make projects happen; utilising our expertise from the first dollar, to the first electron and beyond.

30+ GW in development

across ~250 projects globally

9 GW+ of operational projects 

supported to date with £20 bn+ committed or arranged

Active across 25+ markets

with over 450 renewable energy experts worldwide 


We bring a flexible approach to developing projects, identifying opportunities to drive projects forward with partners and through our expert in-house development team. Our approach is to create new projects and de-risk investment opportunities, paving the way for long term investors and owners. Our in-house project and portfolio management expertise is also available to help manage projects through their construction period and beyond. ​

​We work with strategic partners and our portfolio companies to combine complementary skill sets which deliver successful and scalable development outcomes.

Investment and Finance

The low carbon transition will require a six-fold increase in green finance. This requires an unprecedented flow of investment and finance across the capital structure. We work with our partners, often large renewable energy developers and asset owners, to create innovative capital structuring solutions to help them create value, lower the cost of capital, attract new investors and free up capital to invest in new projects.

Our expert team, focused entirely on green finance solutions and markets, are specialists in developing innovative solutions for complex projects. Our strong balance sheet allows us to invest directly and flexibly across the full capital structure as well as mobilising third party investment and finance.

In addition to investing our own capital, we work closely with Macquarie Infrastructure and Real Assets to mobilise third party investment and finance to accelerate the transition to a new energy mix. This management of capital on behalf of long-term investors such as pension funds and insurances companies, supports the build-out and operation of vital clean energy projects around the world.

Every market has its unique decarbonisation pathway and investment needs, requiring a mix of green technologies and financing solutions. So we don’t specialise in just one technology, we have the expertise to deliver across them all.

We have significant experience in providing solutions to invest in mature technologies, at scale. But we’re also supporting the roll out of innovative technologies that have the potential to shape the energy systems of the future, such as hydrogen, carbon capture and storage, biofuel, EVs,  hybrid projects and helping our clients generate and store their own electricity onsite.
