When it comes to energy storage, thermal energy storage is the low hanging fruit of the industry. The technology is cost effective, simple to operate and effective. In fact, it has even been operating in some buildings for 20+ years. To truly appreciate the benefits of this technology, however, it’s important to understand how it can make renewable energy more viable and be used to uncover hidden opportunities for savings within utility bills. Due to demand charges, the price of commercial energy is roughly 50% cheaper during the night than during the day. Thermal energy storage decouples when energy is purchased from the grid from when it is used, by allowing cooling to be created and stored as ice at night for use at a later time. This session will show how rates are structured in California and how shifting peak loads can reduce energy costs. With the presenter, attendees will review an electric bill from the SCE territory to identify opportunities for savings. The session will also highlight how thermal energy storage can benefit renewables. Unlike fossil fuels, renewable resources have no storage component. Solar energy use results in the often cited “duck curve” related to overgeneration of renewable resources in the afternoon and the need to ramp up power as renewable generation drops off in late afternoon hours. Thermal energy storage can be used when renewable forms of energy are unavailable due to natural weather events or when output diminishes at the end of the day. It can be used to fill in the gaps in demand that renewables create. I will describe in detail the benefit of thermal energy storage for commercial power consumers and the broader benefits for sustainable building. Attendees will be able to identify opportunities for implementing the technology and gain an understanding of design basics. The session will provide pertinent information on how thermal energy storage relates to California Title 24, LEED certification, net zero building design, PLS incentives ($875/kw shifted), connected loads and water usage.
