What are substation batteries?

Substation batteries are large-scale energy storage units installed within electrical substations. Their primary purpose is to supply backup power during outages, support grid regulation, and ensure continuous operation of protective systems.

What is a power substation?

Electricity substations play a role in both stepping up the voltage of electricity for distribution on grid and in transforming it into lower voltages for delivery to end consumers. The Kawerau substation is one of 13 substations within the Bay of Plenty (BOP) region and is interconnected to the grid through both the 110 kV and 220 kV networks .

How does a substation function?

A substation is an installation where electricity is received from power stations and transformed for distribution. At the substation, the voltage is stepped down to distribution levels, and the power is fed into the distribution grid, where it is sent to the final consumers.

Why are substation batteries important?

In the context of battery backup systems, the importance of substation batteries cannot be overstated: Ensuring Continuous Power: During outages, batteries keep critical systems running, preventing blackouts and equipment damage.
