You can order electric trucks, a charger bank or a new production line in a few months. Whether your building can power them is a separate question – and the answer can take years.
The good news: SCE publishes how much room is left on its circuits. You can check your address before you commit to the equipment. Here’s what the data shows, and what to do if the answer is “not yet.”
Why circuits fill up
SCE’s parent company expects electricity use in SCE’s territory to grow about 30–40% by 2035 and roughly double by 2045 as businesses and homes electrify. Large new loads – charging depots and data centers among them – now compete for the same local wires.
That shows up in SCE’s own published data, checked October 13, 2026:
- SCE publishes capacity figures for about 4,250 circuits.
- 315 show no spare capacity today.
- 813 have less than 1 MW of room today and still less than 1 MW five years out in SCE’s plan.
- 416 have room today but drop below 1 MW within SCE’s five-year plan.
The takeaway: spare capacity is planned years out. If your growth plan needs more power, find out where your circuit stands now.
How long the wait runs
- From application to power: an average EV-charging hookup in SCE territory took about 571 business days – a little over two years – counting customer, contractor and utility time.
- Against the state’s target: an independent review for the CPUC found SCE commercial projects averaged 269 calendar days against a 182-day target. 35% met it.
- Upgrades take longer still. As of 2024, SCE told one charging developer that expanding a substation takes four to five years and building a new one at least eight. SCE doesn’t yet publish how long circuit and substation upgrades take – so ask early.
Real projects feel it. WattEV planned a truck-charging site in Baker; in August 2025, SCE determined it could not provide enough capacity at the original site, and the project had to move. In La Puente, Quality Custom Distribution added 1.45 MW of solar and a 3 MWh battery so it could charge more of its 30 trucks than its grid connection allowed.
The state now backs bridging the gap
In February 2026, the CPUC told SCE and PG&E to offer flexible service connections: customers waiting on an upgrade can use more power when the grid has room, with on-site storage named as one way to get there. SCE calls these “bridging solutions.” In SCE’s own pilot, customers got power about 20 months earlier on average.
The state is pushing on the bigger lines too. AB 2493, signed this fall, makes utilities file schedules for major transmission upgrades and adds a CPUC monitor to check them.
What it looks like on real circuits
A sample of nine SCE circuits serving industrial areas in and around Orange County, from SCE’s published data, checked October 13, 2026:
| Circuit | What SCE’s data shows |
|---|---|
| Katella (Cypress) | No spare capacity today, and SCE’s plan still shows it full five years out. |
| Baylor | No spare capacity in any year of SCE’s five-year plan. |
| Packard (Garden Grove) | Full today, and full again five years out. |
| De Mari | Full today and full again at the end of SCE’s plan. The substation behind it is full by then too. |
| Anahurst (Anaheim) | Full today. A brief opening, then the circuit and its substation are full by the end of the plan. |
| Friends (Santa Fe Springs) | No spare capacity today and only a sliver of room (about 0.1 MW) through the rest of the plan. |
| Raybestos (Fullerton) | Full today. A short window opens mid-plan, then narrows again. |
| Leffingwell (Santa Fe Springs) | Nearly full – about 0.3 MW of spare room today, shrinking over the plan. |
| Mallet (City of Industry) | Full today. SCE’s plan shows room opening later. |
The data is a high-level planning view. It reserves nothing and isn’t a service answer for any one building – but it tells you whether to plan ahead.
Where Revel PowerBridge fits
If your circuit is full, Revel PowerBridge puts battery capacity behind your meter so you can run more of what you need while SCE’s upgrade catches up. It works with SCE’s flexible service connection. It doesn’t replace the upgrade – it bridges you to it. Mallet is the textbook case: full today, room planned later, and PowerBridge covers the gap.
Revel is booking 2027 PowerBridge sites now.
Bottom line
Check before you commit. Your trucks, chargers or second shift can arrive long before your circuit has room for them. Knowing your circuit’s status today turns a surprise into a plan.

ROOFTOP SOLAR
Commercial grade rooftop solar is ideal for: manufacturing, warehousing, logistics, industrial, retail, hospitality buildings and more with over 10,000 sq. ft. rooftops.
CARPORT SOLAR
Free standing carport solar generates added solar power for properties with limited rooftop space. Added benefits include shading and protection for employees vehicles.
ENERGY STORAGE
Crucial for reducing peak demand charges. Automated to supply electricity when your panels won’t. Energy storage is ideal for businesses that incur significant peak charges.
EV CHARGING STATIONS
As the popularity of EVs increase, so does the demand for on-site EV charging stations. This sustainable amenity has become a parking lot fixture for employers.
