Currently, large power plants generated most power and provided to consumers. Electric energy storage offers a double-way flow of power that makes some obvious advantages for support of the power grid. For example, storage is particularly useful for offsetting the intermittent nature of wind and solar photovoltaics, which don’t produce power on demand as a fossil fuel power plant does.
Having a battery behind the meter provides a great deal of flexibility in energy using manage for an individual consumer. Consumers are allowed to cut their electric bills by reducing how much power they consume during peak hours when waste a high power costs, which is usual situation in many states such as California.
Houses with rooftop solar panels on the top and batteries can actually use energy from their solar systems during power outages and, with The right amount of storage, have sufficient power to last for days if the grid is out. And with enough storage, they can disconnect from the grid indefinitely – a development utilities fear.
Some states have net metering, programs in which utilities purchase the excess electricity from solar panels that’s fed into the grid. In combination with net metering, behind-the-meter storage creates the opportunity for customers to buy power from the grid when prices are low and then sell stored energy from batteries when prices are high. This practice, known as arbitrage, has led to concerns at utilities which have levied large additional charges for equipment installations in some places.
Commercial and industrial customers stand to benefit from behind-the-meter storage as well. They can reduce their usage during times of peak demand and cut so-called demand charges – fees for maximum power usage – that can dominate how much they pay for energy.
