A note from our founders
We Built What We Couldn’t Find
When GPS Renewables started off as TEPC and CBG project developers, we ran headfirst into a problem the industry rarely talked about openly: those certain critical equipments were letting projects down.
Domestic options often underperformed. International alternatives were priced far beyond what most Indian CBG project economics could support, even though they were technically strong.
We are technology developers first. We know exactly what a project needs to be viable, which tolerances mattered, which failure points caused the most downtime, and where the real ROI was made or lost.
Every product we develop or partner on must meet the standard: segment-leading performance at a cost that makes project economics work.
We built OptiMAXX, not as a standalone product business, but as the equipment division we needed ourselves.
Then We Got
to Work
The OptiMAXX Mandate
Highest performance in its class. Segment-leading technology. Cost-competitive without exception. The highest ROI in the segment — always.
