Guascor Energy

What Guascor Energy does

Guascor Energy is a Spanish manufacturer and service provider of gas and diesel internal combustion engines designed for power generation, cogeneration, waste-to-energy, and marine applications. Founded in 1966 by José María Gutiérrez Ascunce and headquartered in Zumaia, Gipuzkoa, Spain, the company operates as Guascor Energy S.A.U. — a privately-held single-member public limited company with 300+ employees and a presence across 5 continents. The company operates a proprietary R&D center in Vitoria-Gasteiz (established 1996) and produces engines ranging from 180 kW to 2 MW across three industrial gas engine series (S, H, E) plus marine and diesel product lines. Core technology includes innovative pre-combustion chambers enabling NOx emissions as low as 200 mg/Nm3 and 45.7% electrical efficiency in the 2MW class, a proprietary fuel blending system capable of switching between natural gas and biogas or hydrogen blends at full power, and hydrogen-ready engines supporting up to 50% H2 blending (with 100% H2 planned for the E Series).

The company's revenue model is anchored in hardware sales of engines and OEM spare parts, supplemented by professional services (technical training at the Guascor Training Center) and a growing managed services offering (Remote Care Service for remote monitoring and predictive maintenance). Go-to-market is executed through a combination of direct enterprise field sales (with global services directors traveling to customer sites) and a channel network of more than 50 distributors and partners worldwide including Dordtech (Netherlands), Drivetrain (Australia/New Zealand), Alternatif Power (Turkey), Kreativ Recovery (Malaysia/PNG), and Jiamphattana Energy International (Thailand). Customer segments span industrial power generation, combined heat and power (CHP) cogeneration, waste-to-energy from biogas and syngas, mechanical drive applications, and marine propulsion/auxiliary power. Named enterprise customers include Mlekpol Dairy Group (Poland), Acushnet/Titleist (USA), Hancheng Coal Mine (China), Balearia (Spain), and Knutsen OAS Shipping. Pricing is quote-based and custom-configured by power output, fuel type, and application requirements, with no publicly disclosed pricing.
