In line with its philosophy of independence and diversity, Morongo Band of Mission Indians hired EMCOR Energy & Technologies to design and manage a cogeneration plant for its casino that was constructed in 2004. The idea was to provide a reliable source of electricity for the facility that would protect it from rolling blackouts or power shortages caused by heavy usage in other parts of the state.
Some of the technical requirements driving the project were:
- 100% off grid power generation
- Power generation redundancy
- Fuel redundancy
- Temporary power during construction of casino and other facilities
Power is generated by four gas-fired 2MW Caterpillar G3520C engines for providing primary power and three diesel-fired Caterpillar 3516B engines for the backup system. The gas-fired engines have a rated efficiency of 38.2%.
