Time To Upgrade 

With an aging and carbon intensive energy infrastructure, the owners wanted to upgrade the systems to make the resort eco-friendly (sustainable)(green)(carbon-neutral), reduce operating expenses, and provide resilient always-on-power.  

Easier said than done in an area known for foggy days in the summer, which reduces the new Solar PV system’s production and no utility grid to tie into. Redundant backup systems and a new battery energy storage system, designed and engineered by ESI and all managed with the BAM’s™ sophisticated software, make for a truly resilient and eco-friendly solution that even the Sea Otters would love.  

The resort previously ran exclusively on a Capstone Turbine generator that is still serviceable and was state of the art when installed 17 years ago. The owners wanted to keep the generator as part of the updated energy infrastructure but propane costs were rising quickly and the system wasn’t as reliable as the resort required. Consequently, they looked at upgrading their entire energy infrastructure.   

The Ultimate Solution 

 After interviewing numerous potential vendors, the owners chose ESI to engineer and design an eco-friendly, compact, resilient energy system to meet the resorts’ needs today and well into the future. ESI engineered a path to integrate the Turbine generator (no one else wanted to touch it!), while adding a new Solar PV Field, a redundant generator, and upgrading the electrical switchgear to ESI’s BAM™ Micro-Grid, all integrated with our Advanced Battery Energy Storage System™ (BESS).

Treebones’ new energy infrastructure is driven by a 54kW BAM™ Micro-grid with redundant (N+1) hot swappable inverters and Remote-Controlled Circuit Breakers (RCCBs). Energy from the 30kW solar array is stored in ESI’s 150kWh Advanced Battery Energy Storage System™ and is augmented by the 2 redundant generators. The system is monitored and managed remotely at ESI’s Demand Response NOC.  

 

Good for the Environment and the Bottom Line  

With ESI’s BAM™ Micro-Grid acting as the conductor for the resort’s energy demands, Treebones should realize operating cost savings of over $200,000 annually. Incorporating renewable resources cuts their carbon footprint in half, keeping the promise of “perching lightly” into practice and provides a much more resilient and efficient energy system to power the resort.
