PPA
Power Purchase Agreement
A fixed price below grid rates. Savings from day one, without tying up capital.
A PPA (Power Purchase Agreement) is a long-term renewable energy purchase contract between a producer and a business consumer. The organisation locks in an energy price below grid rates for the entire contract duration — typically 10 to 20 years — with zero equipment investment. By removing the upfront investment barrier, savings start on day one.
It is the solution for companies with high energy consumption that want to stabilise costs, reduce exposure to volatile power prices, meet ESG targets, and decarbonise without committing capital or changing operations. The system can be installed at the company's premises (on-site PPA) or on a remote site with grid injection (off-site PPA).
We handle everything end to end — engineering, financing, permitting, installation and long-term operations. The contract is structured to fit: price definition, term, delivery mode, minimum production guarantees and termination conditions, working with financial and engineering partners where applicable.
