Nestled in the Rocky Mountains, Mount Engadine Lodge is a natural haven for those looking to get away from it all. Encompassing two buildings, 8000 square feet, 19 guests + staff, and all the typical fixtures of a commercial kitchen and hotel, the energy requirements are substantial.
Mount Engadine Lodge is completely self-sufficient for electricity and heating, relying exclusively on diesel and propane for this purpose. Electricity was provided by two 50 kW continuous-duty diesel generators operated in 10 day rotations. Heating is provided primarily by two propane furnaces with an assortment of electric heaters throughout.
3 x SMA Sunny Island 5048 inverters, for a total of 15 kW continuous
duty 208VAC 3-phase power.
System operation is simple and automatic. During periods of low electricity demand, the system will switch to battery/inverter mode and shut the generator off. When the load increases or the battery voltage becomes low, the generator is automatically started. It will then run the loads in the lodge and charge batteries at the same time.
There's still work to be done on this project. Energy efficiency measures are required to get the best value of the system. There are assorted timed loads that need to be fine-tuned so they aren't running during the generator off times. The owners have been empowered with system performance data and we will work together over the next few weeks to refine the operations of the system to get the best value from the hybrid system.
The client has completed many of the energy efficiency upgrades. By manually powering off the effluent treatment plant at night, the system is able to silence the generator typically 8 hrs per night. In the morning, once the lodge starts up, the generator will run for 4-5 hours before going back to battery. The number of daily cycles varies according to the number of guests.
75% Fuel Savings
We are still waiting for time to have to fill up the main tanks, but our estimates based on levels compared to normal show that the hybrid system is using approximately 75% less diesel fuel than the generator-only solution! We are very pleased with that result
