1. Development of RES
In developed countries, renewable energy sources (RES) are being actively deployed. However, weather conditions rarely meet the countries' energy demands, so an energy storage can accumulate electric energy when it is not in demand, and produce it when it is needed.
2. Bringing HPPs to a new level of effectiveness
The old equipment of heat power plants (HPP) will be replaced not with new units, but with energy storages. The remaining equipment will work in the constant power mode that minimizes the wear and tear and maximizes the efficiency. Not only will this strategy reduce the maintenance and repair costs, but it will also increase the capital productivity and decrease the polluting emissions.
3. Building of new NPPs
Nuclear power plants (NPP) work in constant power mode and for that reason building of new NPPs will require transregional interchange to be significantly increased. Energy storages will accumulate the energy produced by NPPs and deliver it to the grid when necessary reducing the interchange.
4. Energy system reliability guaranteed
Energy storages will reduce hardware failures, equalizing power plant equipment loads. Moreover, they can replace the hot reserve provided by HPPs and, hence, reduce the fuel consumption.
5. Reducing maintenance costs
Growing manufacturing lead to the power peaks overloading the feeding substations. Deploying an energy storage at a substation or at a customer's place of business will smooth these peaks, reducing the load on the grid.
6. Bridging independent grids
An energy storage allows one to accumulate energy from grid A at the time of low demand and send it grid B when it is necessary.
