Energy Storage Helps Hotel Reduce Demand Charges by 10%
The Ocean Park Inn in San Diego installed Stem’s energy storage system and is expected to save an average of $4,500 per year, lowering its annual demand charges by more than 10 percent. The combination of San Diego Gas & Electric’s energy storage incentives and Stem’s financing plan allowed the hotel to activate the system for no upfront costs.
Like most hotels, the Ocean Park Inn runs a variety of energy-intensive systems to meet guests’ needs, causing periods of high peak demand, especially when these operations overlap. The highest peaks were resulting in costly demand charges, adding up to 50 percent of the hotel’s utility bills.
Stem generates monthly energy savings by learning the hotel’s energy usage patterns, charging when energy prices and demand are low and deploying stored power to offset peaks.
The hotel is also saving energy by spreading out energy-intensive activities with the help of Stem’s PowerScope software platform. Stem’s software displays real- time and predicted energy use, providing visibility into how the hotel’s energy usage patterns translate to costs. With this insight, hotel staff can assess the value of operational changes they are considering and predict monthly energy costs before the bill arrives.
