The natural gas fuelled plant was ordered in October 2017 by Pemcorp, a Mexico-based independent power producer, on behalf of the owners, Texas-based Arroyo Energy Investors, which specialises in power generation projects. The plant operates seven Wärtsilä 50SG gas-fuelled engines, each with an output of 18.7 MW.

The facility provide the electricity supply for a major Asian-owned automobile factory in the city under a long-term power purchase agreement. Full operations commenced in September 2018, only 11 months after the signing of the original order with Wärtsilä.

The O&M agreement between Wärtsilä and Pemcorp, which was signed in September, includes a 15-year Guaranteed Asset Performance Agreement. Additionally, Wärtsilä is providing a Recovery Guarantee for the generator sets to ensure a rapid recovery process in the case of an unforeseen event causing an interruption to the power generation.

“Because of our PPA obligations, it was essential to have extremely fast response, both in time-to-market and in operations in order to provide high-quality power to our customer. Wärtsilä succeeded in supplying and constructing the plant in just 11 months, which was an impressive feat” commented Matthew Ginzberg, principal, Arroyo Energy Investors.

“The high reliability offered by our multi-unit power plant solution, combined with high simple-cycle efficiency, were the key factors in our being awarded this contract. The value proposition that we are able to provide represents a complete package. It combines our equipment, procurement, and construction (EPC) capabilities with the backing of O&M service, to give a winning format” said Sampo Suvisaari, the regional director for Wärtsilä Energy Solutions.
