With heating and electricity costs rising exponentially each year, the Westin Ka’anapali Ocean Resort Villas northern expansion property was seeking a unique way to save on utility bills, a major part of its overhead costs, while significantly reducing its carbon footprint. With increased efficiency, reduced carbon emissions, and quick ROI it was an easy decision. The answer was a combined heat and power (CHP, also known as cogeneration) application from Elite Energy.
Elite installed a 590-kilowatt (kWe) diesel unit to provide electricity for the resort, with all of the recovered heat from the EnviroGen Energy Module being used to offset the purchase of propane to heat domestic hot water, pools and spas. The module utilizes the standard, quiet Elite enclosure, ideal for being adjacent to the resort facility. The unit also serves as the emergency generator for the resort, which is owned by Starwood Hotel & Resorts Worldwide, Inc.
The Westin Ka’anapali Ocean Resort Villas discovered hotel, resort, and vacation ownership facilities are excellent candidates for CHP. They have electrical and heat loads that are required everyday, evening and night. Elite’s modules are sized and designed to optimize the electrical and heat requirements of the building. Over 80 percent of the energy value of the fuel is utilized to help reduce energy costs for the client. Thanks to the high efficiency of CHP compared to typical utility plants, clients can save as much as 20% on energy costs.
