NEXT GENERATION ENERGY
As we continue to navigate the evolving landscape of energy management, Thermal Energy Storage (TES) systems are emerging as a game-changer for industrial customers. By leveraging TES, businesses can significantly reduce energy costs, enhance operational resilience, and improve their environmental footprint
What & Why
Thermal Energy Storage (TES) systems are revolutionizing the way industrial facilities manage their cooling needs, offering significant cost savings, operational advantages, and environmental benefits. By leveraging TES, businesses can not only reduce their energy bills but also enhance their sustainability and resilience.
TES systems store excess thermal energy for later use, typically by producing ice or chilled water during off-peak hours. Common types include ice storage, chilled water storage, and phase change materials.
These systems integrate seamlessly with existing chillers and HVAC equipment, allowing for smaller overall mechanical systems.
The basic operation involves:
Reduced Peak Demand Charges: Often 30-50% of utility bills. Off-Peak Cooling Production: Shift cooling to times when energy rates are typically 30-70% lower. Downsizing Mechanical Equipment: Smaller chillers reduce capital and operational costs.
Improved System Reliability: Redundant cooling capacity enhances system reliability. Extended Equipment Life: Reduced cycling and peak operation extend equipment lifespan. Buffer Against Power Interruptions: Emergency cooling capacity during grid outages or brownouts.
Reduced Carbon Footprint: Shift energy use to times when the grid is cleaner. Lower Refrigerant Use: Smaller mechanical systems reduce refrigerant consumption. Support for Renewable Energy: Manage load timing to support renewable energy integration.
Emergency Cooling Capacity: Maintain operations during grid outages or brownouts. Demand Response Events: Continue operations during demand response events. Protection Against Energy Price Volatility: Future-proof your cooling needs against rising energy costs.

TPI Efficiency can help businesses maximize the benefits of on-site Thermal Energy Storage by integrating it into a broader energy management scheme that enhances efficiency, reduces costs, and supports sustainability goals.
EIA: Energy Storage for Electricity Generation
An energy storage system (ESS) for electricity generation uses electricity (or some other energy source, such as solar-thermal energy) to charge an energy storage system or device, which is discharged to supply (generate) electricity when needed at desired levels and quality. ESSs provide a variety of services to support electric power grids. In some cases, ESSs may be paired or co-located with other generation resources to improve the economic efficiency of one or both systems.
Types of energy storage systems for electricity generation
The five types of ESSs in commercial use in the United States, in order of total power generation capacity as of the end of 2022 are:
Other types of ESSs that are in various stages of research, development, and commercialization include capacitors and super-conducting magnetic storage.
Hydrogen, when produced by electrolysis and used to generate electricity, could be considered a form of energy storage for electricity generation. Thermal ice-storage systems use electricity during the night to make ice in a large vessel, which is used for cooling buildings during the day to avoid or reduce purchasing electricity when electricity is usually more expensive.
Electricity generation capacity of energy storage systems
Two basic ratings for ESS electricity generation capacity are:
Power capacity—the maximum instantaneous amount of electric power that can be generated continuously and is measured in units of watts (kilowatts [kW], megawatts [MW], or gigawatts [GW])
Energy capacity—the total amount of energy that can be stored in or discharged from the storage system and is measured in units of watthours (kilowatt-hours [kWh], megawatt-hours [MWh], or gigawatt hours [GWh])
