Five Benefits of Energy Storage

1. Environmental benefits. Energy storage has many environmental benefits that can make it a valuable tool for meeting sustainability goals. By improving the overall efficiency of the power grid, storage accelerates the broader adoption of renewable energy. On a more local level, an energy storage system has no emissions, so it can be placed anywhere in a facility with no immediate environmental or air quality impacts.

2. Demand charge reduction. Depending on location, many commercial and industrial facilities are subject to demand charges on their energy bills. These charges are based on the 15-minute period in which the demand for energy is highest throughout the day and in some cases, can account for 50 percent of the total energy bill.

3. Participation in demand response programs. Demand response for commercial and industrial facilities traditionally involves ratcheting down usage at times of peak demand. Energy storage can enable participation in demand response markets without impacting on-site energy use or operations.

4. Maximizing time-of-use rates. Energy storage systems can shift consumption of electricity from expensive periods of high demand to periods of lower cost electricity during low demand. This reduces the risk of lowering the value of on-site solar if tariff structures change over time, and peak demand periods shift to the evening when the sun isn’t shining.

5. Emergency backup — resilience. Planning for emergency backup power is an essential part of a resilience plan.

The advantages of the home energy storage system are:

(1) Reduce emissions, reduce pollution and demand from power grids that rely on coal and gas;

(2) Safe for power failure, and provide backup power supply in case of power failure or emergency;

(3) Reduce costs and save money by using less grid energy;

(4) Be energy-independent and store excess solar energy to reduce grid use;

(5) Reduce peak demand, support the power grid during peak hours and provide power grid stability services;
