The Los Angeles Department of Water and Power has decided to follow its neighboring utilities in deploying grid-scale batteries. Today, LADWP finalized its partnership with Doosan GridTech and KTY Engineering to deliver on its first battery energy storage system.
The utility recently approved procurement of a 20-megawatt/10-megawatt-hour lithium-ion system to go into the Beacon Solar Plant in the Mojave Desert. The system will increase utilization of the desert'ssolargeneration, as well as provide grid reliability service in the wake of the Aliso Canyon natural gas disruption, which prompted LADWP to accelerate delivery from 2020 to March 2018.
LADWP has an impressive grid storage capacity of 1,296 megawatts, but that's almost entirely from the Castaic pumped hydro storage facility.
To install its first battery system, LADWP turned to Doosan GridTech, formerly known as 1Energy Systems* before the acquisition by the South Korean conglomerate Doosan Heavy Industries in July 2016.
This marks several firsts for the company, said Vice President of Product Management Rogers Weed.
It's the first major contract since the integration with Doosan, the first project in California for the Seattle-based company and the first time GridTech has provided turnkey EPC services on a project, flexing the financial muscle that comes with a large corporate backer. Previously, 1Energy had involved utility partners in some of the development and procurement work.
“We’ve realized that a lot of customers, for risk management purposes, want a single point of accountability, a full-wrap, turnkey EPC solution,” Weed said. “As 1Energy we didn’t have the balance sheet, but we clearly have that as part of Doosan.”
Many know Doosan GridTech as a software specialist, and software to manage storage systems and fleets of distributed resources remains a core expertise of the firm. But there's not a ton of money in standalone storage software yet, because few customers have enough battery systems linked together to justify buying fleetwide management tools.
Good, old-fashioned project execution, though, can turn a profit in the meantime.
“There’s a lot of revenue growth there in the foreseeable future,” Weed said. “We believe that, longer-term, software has better margins than the EPC business, but there’s really barely an opportunity to do a software-only business at the moment.”
