While exporting electricity to the grid is no longer such a lucrative prospect, using solar power to reduce one’s own energy consumption still brings price savings. When power is drawn from the electrical grid at a flat rate, there is no need to store that solar power.
Storing excessive thermal energy to be used in colder times is one of the oldest forms of energy storage known to us. Recent research and development have made it possible to use this energy for grid applications. Learn more about the different types of thermal energy storage here.
Since the electrical grid has existed, so has the need for stored forms of energy that can be drawn on to meet times of peak demand and regulate frequency. In the past, the bulk of this extra energy came from fossil fuel plants that were fired up and down with demand.
Are energy storage systems profitable? How does their value relate to their costs? How will this change in the near and long-term future? Learn more about the economics of energy storage and the business case for these solutions.
For most European countries, the grid as we know it — the electrical power transmission network consisting of transmission lines, transformers, substations and much more — was built in the early 20th century. A century later, it is beginning to transform into something much smarter.
Where can energy storage systems (ESS) generate value? How are they used for grid ancillary services such energy arbitrage, frequency regulation, T&D deferral and more. Learn about the different applications of stored energy for grid operators, utilities and end-users.
