battery-gas hybrid system

US energy provider Southern California Edison (SCE) unveiled its new battery-gas turbine hybrid system developed by GE to help the utility improve its grid reliability.The system LM6000 Hybrid Electric Gas Turbine (Hybrid EGT) comprises a 10MW/4.3MWh battery energy storage plant and a 50MW gas turbine to help SCE secure its energy supply against demand during peak periods.

Commenting on the launch of the energy generation and storage integrated system, Ron Nichols, president of SCE, said: “The new system will help SCE better utilise the resources on the grid, provide enhanced reliability, reduce environmental impact, and reduce the cost for our operations and for our customers.

“This technology also allows us to continue to expand our use of solar, wind and other renewable resources.”

According to GE, the system will help SCE reduce its carbon footprint by 60% and save up to two million gallons of water used in cooling of energy plants.

Reinaldo Garcia, CEO of Grid Solutions at GE Energy Connections, added: “Storage and the ability to quickly push power to the grid also play a key role in emergency situations, dispatching energy immediately to the grid ensuring that we are able help keep the lights on for everyone.”

Using energy stored in the 10MW/4.3MWh battery storage system, SCE will be able to meet its grid demand even when the gas turbine and other renewable energy resources are not at their peak.

The system is claimed to be the world's first battery-gas turbine hybrid plant.

SCE plans to use the technology to meet renewable energy standards set by the California state government stipulating 50% of the state's total energy capacity be generated from clean energy resources by 2030.

Moreover, the development is expected to help the utility improve its customer services by providing its 5 million consumers with clean and affordable energy. Read more...

Completion of battery energy storage plant

In February, SCE announced the completion of a 20MW energy storage plant to reduce peak demand on its grid network in Ontario, California.

The energy storage system stores electricity during off-peak periods and provides it into the grid during peak periods to power up to 15,000 homes for 4 hours.

The development of the 20MW energy storage system fell under plans by SCE to eliminate the use of fossil fuels as far as possible, following the closure of the utility’s Aliso Canyon gas-fired plant in 2015.
