Los Angeles Approves $1 Billion Scattergood Power Plant Retrofit for Hydrogen Transition

The Los Angeles City Council has voted 10-3 to proceed with a massive modernization of the Scattergood Generating Station in Playa del Rey. The project, estimated to cost ratepayers between $800 million and $1 billion, will replace the facility's 1950s-era natural gas boilers with new combined-cycle turbines capable of burning a blend of natural gas and green hydrogen. For Los Angeles residents, this represents a major financial commitment aimed at keeping the lights on during peak demand while attempting to transition the city's power grid away from pure fossil fuels.[2][4]

The Los Angeles Department of Water and Power (LADWP) argues the retrofit is a necessary utility cost to maintain grid reliability on the city's Westside. This specific service area powers critical municipal infrastructure, including Los Angeles International Airport and the Hyperion Water Reclamation Plant. The existing Scattergood units currently rely on ocean water for cooling—a practice now banned under state environmental regulations to protect marine life—and are legally mandated to permanently retire by December 31, 2029.[4][6]

To replace that lost capacity, the new turbines are engineered to initially run on a mixture of 70 percent natural gas and 30 percent green hydrogen. The utility's stated long-term objective is to scale the facility to operate on 100 percent hydrogen as the technology and supply chain mature. Green hydrogen is produced by splitting water molecules using renewable electricity, such as solar or wind power, meaning the fuel itself does not emit carbon dioxide when combusted.[2][4]

The project's substantial price tag recently faced a significant complication when the federal government withdrew $1.2 billion in funding from California's clean hydrogen hub, known as ARCHES. LADWP had anticipated receiving a $100 million subaward from that federal pool, which would have helped shield local ratepayers from a portion of the retrofit's upfront costs.[3][4]

Despite the sudden loss of federal dollars, utility officials and the City Council majority maintained that the project remains an essential investment. LADWP projections indicate that failing to replace the Scattergood units could lead to severe power outages and economic disruptions by the early 2030s, particularly during extreme heat waves when solar generation drops off in the evening and grid demand peaks.[3][6]

The council's decisive vote officially rejected an appeal from a broad coalition of environmental organizations, who argue the city is making a billion-dollar mistake. Climate advocates contend that green hydrogen is currently prohibitively expensive, requires massive amounts of dedicated renewable energy and water to produce, and remains largely unavailable at the commercial scale LADWP requires.[1][5]

Because the modernized plant will still rely heavily on natural gas for the foreseeable future, opponents view the retrofit as a mechanism to prolong the lifespan of fossil fuel infrastructure rather than a clean break. Environmental justice groups also highlighted that combusting hydrogen still produces nitrogen oxides (NOx), which contribute to local smog and respiratory issues in surrounding communities.

Environmental groups urged the city to redirect the $1 billion into non-combustion alternatives, specifically long-duration battery storage and expanded local solar capacity. However, utility planners countered that current battery technology cannot yet provide the firm, dispatchable power required to back up the grid for days at a time. With the environmental impact report now certified, LADWP is authorized to begin the contracting process, though the utility must continue reporting to the City Council on its hydrogen sourcing progress.[2][6]
