Inspired by the lyrics and lifestyle of Jimmy Buffett’s Margaritaville, Margaritaville Vacation Club by Wyndham Resorts is a luxurious, off-grid, beachside resort nestled in a cove fringed by palm trees. Located on Water Bay at the eastern end of St. Thomas, it features over 264 rooms, 2 bars, and 2 pools. The resort owners sought a resilient, cost effective power solution, one that would allow the resort to expand in multiple phases, while lowering their energy costs and becoming less dependent on an unreliable utility grid. In December, the on-site microturbine power plant implemented a C1000 and expanded two years later to include a C800. The site now features two highly efficient, low emission Capstone microturbines that can generate up to 1,800 kW of electricity. E-Finity Distributed Generation monitors the site and can remotely diagnose and troubleshoot issues with their state-of-the-art control system. The cost to operate the propane-fueled, microturbine-based system is roughly half that of purchasing local utility power. This has resulted in over $6 million USD in energy savings since startup, all while the system has delivered 99.9997% uptime.
