People. Flexibility. Relationships. Experience Audubon's combined heat & power (CHP) technology is a gas turbine generator power island facility designed to meet midstream oil and gas producer's on-site power needs at lower-than-grid unit cost. It uses waste heat to serve central gathering thermal du es, while using the remainder thermal energy to co-generate addi onal power via an organic rankine cycle without the need of steam, addi onal fuel, combus on, or emissions. CHP can provide system owners and operators with significant economic, environmental, and reliability benefits. By efficiently providing electricity and thermal energy from the same fuel source, CHP significantly reduces the total primary fuel needed to supply energy to a gas processing plant (see Figure 1). ▪ Power Island Operations - Independent from Power Grid ▪ 45% Reduction in CO 2 and 70% Reduction in NOX Emissions ▪ Decreased Energy Costs/OPEX ▪ Enhanced Energy Resiliency ▪ Reduced Risk from Uncertain Energy Prices ▪ Increased Economic Competitiveness Audubon's CHP Technologies Grid Power with On-site Boiler CHP Systems Figure 1. Efficiency benefit of CHP. The development of CHP is driven by several factors, including:
