Six Flags Magic Mountain Solar Carport Goes Live at 12.37MW

Estimated reading time: 7 minutes · Last updated: 30 October 2026

Six Flags Magic Mountain, the theme park at the edge of Los Angeles County, switched on a 12.37 megawatt solar carport on 1 October 2026 and began exporting power to the grid that day. The system spreads 22,908 RECOM bifacial panels across 36 steel canopies above roughly 4,315 parking spaces. A battery rated at 2 megawatts and 8 megawatt hours sits behind it. Six Flags expects about 20.8 million kWh a year, a figure modelled from the system's rating over a full year rather than measured. The park's goal is to match all of the annual electricity used by the park and the water park beside it. Southern California Edison's grid remains central to how the site runs.

What Six Flags Built Over Its Parking Lots

The installation covers the lots that guests and staff cross on the way in. Thirty-six steel canopy structures carry 22,908 bifacial panels made by RECOM, about 636 panels per canopy. Together they span roughly 637,000 square feet. Underneath, about 4,315 parking spaces now sit in shade, split between 3,544 for visitors and 771 for employees.

The rated capacity is 12.37 megawatts. That puts the array closer to a small power station than to a parking amenity. A battery rated at 2 megawatts of output and 8 megawatt hours of stored energy backs it up. The lots also gained 109 charging connectors for electric vehicles, spread across the guest and staff areas.

The project took more than three years to plan and build. It started sending electricity to the grid on 1 October 2026. Brian Oerding, president of Six Flags Magic Mountain, described the switch-on as a milestone in the park's sustainability effort, in a company release on the project.

Why a Canopy Over Asphalt Can Beat a Rooftop

Hugo Rojas, an engineer and editor at Energies Media, sets out why a carport can outproduce panels on the buildings next to it. The canopies stand higher and spread wider than most roofs. That lets the modules catch sunlight from more angles over more hours of the day.

The bifacial design adds a second source of light. A bifacial panel has solar cells on both faces, so it generates power from direct sun on top and from light striking its underside. At Magic Mountain, that underside faces a dark asphalt lot that throws glare back up all afternoon. Rojas argues this turns the pavement into part of the generating surface rather than dead space beneath the steel.

Open ground matters as much as the panel type. A roof is cluttered with vents, air-conditioning units and shadows from taller buildings. A theme park lot has none of these. Rojas notes that the clear, mostly flat expanse let the designers fit close to 23,000 panels without altering any building on the site.

What the 20.8 Million kWh Figure Does and Does Not Show

The headline number is annual and modelled. Six Flags expects the system to produce about 20.8 million kWh in a year. That estimate comes from the array's rated output across twelve months of Southern California sunshine. It is not a reading taken from the meters since October.

The park's ambition rests on that figure. Six Flags aims to offset all of the electricity consumed each year by the theme park and the neighbouring water park. Offsetting is an annual accounting goal. It means generation over the year should equal use over the year, not that the panels power every ride at every moment. Whether the lot actually out-produces the park will only be clear once a full year of measured output exists.

Solar Optimum, Six Flags' partner on the project, presents the work as renewable energy that helps organisations hit sustainability targets while bringing environmental and economic returns. Rojas adds a resource point. Solar generation uses none of the water that fossil-fuelled plants need to produce the same megawatt hour.

Why the Grid Connection Stays Essential

The carport does not take Magic Mountain off the grid, and Six Flags has said as much. The parks remain hooked up to Southern California Edison, the regional utility. They pull power from the grid when on-site generation runs short. When demand is met and the battery is full, they send the extra out.

Timing explains why. A theme park's heaviest loads often land on hot, crowded summer afternoons, when air conditioning and ride motors run hard together. Evenings bring a different problem. The panels produce nothing after sunset, which is exactly when the lights and night rides often run.

The battery helps at the margins. At its 2 megawatt rating, the 8 megawatt hour store can discharge at full output for about four hours. Rojas calls that capacity large for a commercial site but small next to what a full park uses in an evening. In his reading, the utility link is the normal way the site operates, not an emergency fallback.

What a Theme Park Lot Suggests for Other Pavement

Rojas argues the lesson is about parking surfaces rather than theme parks. Malls, stadiums and airport garages all sit under open sky with large paved areas. In principle, each could carry the same steel canopies and let its asphalt serve two purposes at once.

He also points to developers watching the Magic Mountain model. These include smaller rural utilities considering whether to buy existing solar capacity instead of building new arrays from scratch. That is a different route to adding solar, but it reflects the same search for capacity that does not demand fresh land.

The open question is how far the economics travel. Magic Mountain had a single owner, a large flat lot and a long planning runway of more than three years. Sites without those advantages may find the steel, the grid connection and the battery harder to justify.

The case for and against the parking-lot model

The bottom line

Six Flags Magic Mountain has turned about 637,000 square feet of parking into a 12.37 megawatt generator, with 22,908 bifacial panels, an 8 MWh battery and 109 charging connectors. The engineering case is persuasive. Elevated canopies over an open, reflective lot avoid most of a roof's limits. What the project has not yet shown is its real annual output. The 20.8 million kWh figure is a rating, and the goal of matching all yearly use at the theme park and water park is an accounting target that still depends on Southern California Edison after dark and on hot afternoons. The first full year of metered data, due after 1 October 2027, will settle whether the lot out-produces the park.

What to watch

• Watch for measured output once the array completes its first full year, one year after the 1 October 2026 switch-on, to see whether it reaches the modelled 20.8 million kWh.
• Watch whether Six Flags reports that generation has matched 100% of annual use at the theme park and water park; no date for such a report has been set.
• Watch how the 2 MW / 8 MWh battery and the Southern California Edison connection handle the park's first peak summer season with the array running; no specific date has been given.
