A battery energy storage system (BESS) is an electrochemical device that charges (or collects energy) from the grid or a power plant and then discharges that energy at a later time to provide electricity or other grid services when needed. Several battery chemistries are available or under investigation for grid-scale applications, including

Large-scale solar heating for the building sector requires an adequate Thermal Energy Storage (TES) strategy. TES plays the role of load shifting between the energy demand and the solar irradiance and thus makes the annual production optimal.

The difference between FTM and BTM is the energy system''s position in relation to the energy user''s electric metre. Any energy generation or storage source that is interconnected to the electric grid without an associated load behind the same electric meter (for example a home or business) is referred to as a front-of-metre system.

In Alberta, you can choose between a regulated or competitive provider to energize your home or business. Direct Energy Regulated Services is a regulated retailer.
