Who we are

The technical depth of large global engineering firms, without the red tape.

BTY is an award-winning advisory and delivery consultancy with a 48-year track record across global infrastructure. Our Renewable Energy Services team supports developers, investors, and lenders across wind, solar, battery storage, and powered land — at every stage from origination to construction and operations.

We work at the intersection of rigorous engineering analysis and the financial model. We don't just identify risk: we quantify it, contextualize it, and tie it back to the assumptions that drive valuation, debt sizing, and returns. That's the difference between a report that gets filed and analysis that informs the decision.

Why BTY

Accountable diligence and delivery with a senior team tailored to your project

01

Senior-led service delivery, by design

Every engagement is led by senior advisors with direct transaction experience — not delegated down a chain. Our team has been built by attracting practitioners from the global engineering majors into an agile, boutique structure.

02

A financial lens on every technical question

Our analysis is built for decision-makers. From energy yield variability to O&M assumptions, CapEx benchmarks to interconnection contingencies, our work ties directly to the financial model — sharpening valuation, informing debt sizing, and giving you leverage in negotiation. Technical insight that travels straight to the term sheet.

03

Regional fluency, global perspective

Construction cost benchmarks. Interconnection queue dynamics. Permitting timelines that actually reflect the jurisdiction. With offices and active projects across North America, Ireland, the UK, and Türkiye, our advice is grounded in the market your asset operates in — not extrapolated from one half a world away.

04

Agile, responsive, predictable

Rigorous analysis, one phone call away. We act as an extension of your team — solutions-focused, rapid, and consistent across the project lifecycle. No surprises.
