Our Story
Neptune Infrastructure Associates was founded with a simple goal - to help investors and asset owners lead with confidence in an increasingly complex renewable energy market.
After years working at the forefront of the energy transition, including leadership of major offshore wind assets, our founder Hamish Yates recognised a growing gap between asset ownership and operational delivery.
Projects were becoming larger, partnerships more intricate, and decision-making more fragmented.
NIA was created to close that gap - combining the commercial insight of investors with the practical expertise of operators.
Today, we partner with clients across the full lifecycle of renewable assets, simplifying complexity and helping them achieve stronger alignment, clearer oversight, and better performance - for shareholders, stakeholders, and the planet.
At Neptune Infrastructure Associates, we believe effective asset management is about more than oversight - it’s about clarity, alignment, and action.
Our work is built on a simple goal: to help owners and investors make better decisions, free up time for what matters most, and lead with confidence in increasingly complex markets.
As the energy transition accelerates, the need for practical, data-led, and human solutions has never been greater. That’s where we focus our efforts every day - delivering support that creates real, measurable value for our clients and for the industry as a whole.
