Duke Energy Renewables to Install 200-MW Wind Project in Texas

LCG, April 12, 2019--Duke Energy Renewables, a commercial business unit of Duke Energy, yesterday announced it will build, own and operate the MesteƱo Wind Project, located in southern Texas. The power generated by the 200-MW project will be sold into the ERCOT market, and Duke Energy Renewables will enter into a long-term hedge agreement covering the majority of the expected wind energy production. Construction has commenced, and the project is scheduled for completion by year-end.

Recovered Energy Generation Projects On-line in North Dakota

LCG, February 13, 2009--Ormat Technologies yesterday announced that two, 5.5 MW recovered energy generation projects recently achieved commercial operations at two compressor stations in North Dakota along the Northern Border Pipeline. Two more projects are scheduled to commence operations by year-end.

The compressor stations are driven by natural gas-fired turbines, and the Ormat heat recovery systems use heat exchangers to extract the energy from the gas turbine exhausts, which are at a temperature of 800-900 degrees F. The energy is used to vaporize a working fluid to drive a turbine in an Organic Rankine Cycle system designed by Ormat Technologies, rather than a traditional steam system using water as the working fluid.

The use of another working fluid not only enables the relatively low temperature exhausts to support the power generation system, but it eliminates the need for water. The design has zero or near zero emissions, and its fuel is the waste heat from the compressor station.

The electricity generated from the projects is under power purchase agreements with Basin Electric Power Cooperative (BEPC) of Bismarck, North Dakota.
