COMBINED HEAT & POWER (CHP) BUSINESS IN SPAIN
SNIACE SUCCESS STORY
Until 2013, the Combined Heat and Power (CHP) business in Spain was subsidized, at which point new legislation significantly reduced payments to CHP plant operators. Additionally, in 2015 new European legislation ruled on the deadlines to reduce environmental impact of large combustion plants.
Sniace, a dissolving pulp and viscose fiber producer in Spain, was challenged to update two aeroderivative gas turbines if they wanted to bring their power plant back to life.
Sniace collaborated with GE to give their sites the capabilities to restart operation after two years of being idle. GE collaborated with Cogen – an energy services company that Sniace does business with – to repair and upgrade one of their units to comply with the new regulations. For Sniace’s second unit, our services team offered a Dry Low Emissions (DLE) package and provided an LM6000-PF gas turbine lease until 2025, allowing them to turn CAPEX into OPEX.
GE’s team helped the site extend maintenance intervals with a non-water injection solution and at the same time reduce emissions down to 15 ppm NOx, ensuring Sniace will be 100% emissions-compliant. Additionally, an LM6000-PF aero engine lease made the plant more economically viable, eliminating the need to use a gas boiler as the main source of heat for the site, providing a more reliable and cost-effective solution to the process. The upgrade positioned Sniace to restart the viscose fiber plant before the end of 2017, which was crucial for their business plan.
