GRS. Renewable energy projects. About us

GRS IS A SPECIALIST construction company focused on renewable energy projects.

We provide our clients with bankable, internationally competitive solutions to source, validate, finance, execute and operate investment opportunities. Our competitive advantage is based on four key strategic differentials:

We are a vertically integrated company operating on all sections of the renewable energy project value chain (except for technological components). This means we can control costs, harmonize the EPC processes and can arbitrate on technology and systems to provide the optimum solution for any given project. 

We have also secured highly competitive long-term supply agreements with our technology partners giving us a crucial cost advantage.

Our top management is comprised of some of the most respected names in the construction industry with decades or accumulated experience across five continents.

This provides us with an unparalleled level of contacts and insight in international markets and gives us the flexibility to operate in almost any market.

As a Spanish based company we also have the ability to access a broad resource of professionals from one of the World’s most developed and diverse renewable energy markets.

Thanks to this wealth of experience and contacts we have been able to successfully implement our business model in various international markets by combining the strength of major-league tier one technology partners with small scale, cost effective local contracts.

To this “Big-Small” operational model we also bring the direct hands-on experience of having built more than 40 PV Solar Power Plants to be able to provide the maximum security for our clients at the minimum cost.

We also offer specialized PV engineering and consulting services that can draw upon its own certified state-of-the-art laboratory and testing facilities.

As such we can quality test all equipment thoroughly, optimizing plant configurations, and returns.

GRS has also developed its own Balance-Of-Plant (BOP) solutions including our own single-axis tracker – the AXONE – that optimizes the €/kWh produced.


Our Board’s strength is built upon the experience and reputation of some of the most accomplished professionals from the construction industry. Their combined knowledge accrued from the hands-on management of major projects across the globe provides GRS with an unprecedented level of access and prestige for operating in international markets, together with a focused, objectives-based vision that guarantees results.
