CCA vs SCE: what LA solar owners actually pay in 2026

Most homeowners in unincorporated LA County and many LA-area cities are automatically enrolled in Clean Power Alliance (CPA), meaning their electricity bill involves two agencies — not one. Your blended effective rate lands in the 34–35¢/kWh range for a typical SCE residential customer, but exactly what you pay for generation depends on which CPA tier you're on and how your solar export credits are calculated under NEM 3.0's Solar Billing Plan.

Understanding this split is critical before you size a solar system or add a battery, because the economics of exporting power versus storing it are shaped by both agencies simultaneously.

How the CPA + SCE split bill actually works

Southern California Edison owns the poles, wires, transformers, and meters. It delivers electricity to your home and charges you delivery rates for that service. Clean Power Alliance — a Community Choice Aggregator — purchases or generates the actual electricity (the electrons) and charges you generation rates for that commodity.

On your monthly bill, you see one SCE statement. But embedded in that statement are two separate line items: SCE's delivery charges and CPA's generation charges. If you've never noticed this, you're not alone — the layout isn't obvious.

What SCE controls:

• Transmission and distribution charges
• Metering and customer service fees
• Time-of-use (TOU) structure (4–9 PM peak applies to solar owners)
• Your NEM 3.0 / Solar Billing Plan account administration

What CPA controls:

• Generation rate (varies by tier)
• Renewable content of your electricity
• The Sun Storage Rebate program
• CPA's share of your solar export credit

CPA's three generation tiers

When you enroll in CPA — which happens automatically if you live in a participating jurisdiction — you're placed on Clean Power (the default tier). You can opt up to 100% Green or down to Lean Power at any time.

Tier	Renewable content	Generation rate vs. SCE default	Who it's for
Lean Power	~35% renewable	Slightly below SCE default (est. savings ~$2–5/mo for typical home)	Budget-focused; lowest bill
Clean Power (default)	~80% renewable	Roughly equal to SCE default generation rate	Most CPA customers
100% Green	100% renewable	~1–3¢/kWh above SCE default (est. ~$5–15/mo premium)	Climate-priority households

Rates are approximate and change quarterly. Check cleanpoweralliance.org/rates for current figures before making a tier decision.

The tier you choose matters for solar economics: if you're on 100% Green and paying a premium for generation, the math on self-consumption (using your own solar instead of buying from CPA) improves. If you're on Lean Power, the generation premium is lower and the calculus shifts slightly.

NEM 3.0 and the Solar Billing Plan under CPA

Because CPA serves customers through SCE's grid infrastructure, NEM 3.0 (the Solar Billing Plan) applies to all CPA solar customers — just as it does to direct SCE customers. There is no separate CPA net metering program that overrides NEM 3.0.

How your export credits are split

When your solar panels push excess electricity onto the grid, your export credit is calculated in two parts:

1. SCE's avoided delivery credit — reflects what SCE would have charged to deliver that unit of power. This is time-varying and generally low, often 1–3¢/kWh during off-peak hours.
2. CPA's avoided generation credit — reflects what CPA would have charged for that unit of electricity generation. This also varies by time of day and is typically 2–4¢/kWh off-peak.

Combined, most CPA solar owners see effective export rates of roughly 3–6¢/kWh during off-peak hours (overnight, midday) and somewhat higher during the 4–9 PM SCE peak window. These rates are dramatically lower than the ~34–35¢/kWh you pay to import power — which is the core reason battery storage changes the economics so significantly under NEM 3.0.

The 12-month true-up

Like all NEM 3.0 customers, CPA solar owners receive a 12-month true-up. Credits that accumulate in your "bank" offset future charges, but excess credits at true-up are paid out at the avoided-cost rate — not retail. This is another reason oversizing a system without storage is rarely optimal under the current tariff.

The Sun Storage Rebate: CPA's active battery incentive

This is the headline incentive that CPA solar owners should know about in 2026. CPA's Sun Storage Rebate offers up to $2,250 for an eligible home battery system installed at a CPA-enrolled address.

Key details as of mid-2026:

• Available to residential CPA customers in good standing
• Battery must be paired with solar (new or existing system)
• Rebate is paid to the customer after installation and verification
• Program has limited annual funding — availability is not guaranteed year-round
• SGIP residential incentives remain waitlisted in 2026, so the Sun Storage Rebate is currently one of the only active battery rebates available to LA-area homeowners

For a battery system that typically costs $13,500–$17,500 installed (e.g., a Tesla Powerwall 3), a $2,250 rebate represents a meaningful reduction. Combined with the self-consumption and backup value that batteries provide under NEM 3.0, this rebate makes the battery conversation worth having before you finalize any solar design.

Note on federal incentives: The 30% federal residential solar and battery tax credit expired December 31, 2025. There is no federal tax credit for a solar or battery purchase in 2026. Any installer or website suggesting otherwise is working from outdated information.

CPA vs. LADWP: a critical distinction for LA homeowners

Not every LA-area homeowner is a CPA customer. If you're served by LADWP — which covers the City of Los Angeles proper — none of the above applies to you.

Factor	CPA (via SCE grid)	LADWP
Net metering program	NEM 3.0 Solar Billing Plan	LADWP retail-rate net metering (not NEM 3.0)
Export credit rate	Avoided-cost (~3–6¢/kWh off-peak)	Near retail (~26–31¢/kWh effective)
Effective import rate	~34–35¢/kWh blended	~28¢/kWh effective
Sun Storage Rebate	Yes (up to $2,250 via CPA)	No (separate LADWP programs apply)
SGIP	Waitlisted	Waitlisted
Bill structure	Split: SCE delivery + CPA generation	Single LADWP bill

LADWP's retail-rate net metering is significantly more favorable for solar export than NEM 3.0. If you're in LADWP territory, the storage-first strategy that dominates CPA/SCE advice is less urgent — though batteries still provide backup value and self-consumption benefits.

Not sure which utility serves your address? Your bill header will say either "Southern California Edison" or "Los Angeles Department of Water and Power." You can also check at /locations.

What this means for sizing your system

Under NEM 3.0, the optimal solar system size for a CPA customer is typically sized to offset consumption, not to maximize export. Because exported power earns only 3–6¢/kWh but imported power costs 34–35¢/kWh, every kilowatt-hour you self-consume is worth roughly 6–10× more than one you export.

Practical implications:

• Battery storage becomes high-priority: shift solar production into the 4–9 PM peak window instead of exporting it at low rates
• System sizing should be modeled against your actual usage profile, not just your annual kWh total
• CPA tier affects the generation component of your import rate, which in turn affects your self-consumption value

Get a usage-based model at /design-savings or review full solar panel cost ranges before talking to any installer.

Frequently asked questions about CCA vs SCE solar billing

Am I automatically on Clean Power Alliance, or do I have to sign up?

If you live in one of CPA's roughly 30 member jurisdictions — including unincorporated LA County, Torrance, Inglewood, Hawthorne, Redondo Beach, and many others — you were automatically enrolled when CPA launched in your area. You can confirm enrollment and your current tier at cleanpoweralliance.org or on your SCE bill.

Can I opt out of CPA and go back to SCE for generation?

Yes. You can opt out of CPA and return to SCE's default generation service at any time, though SCE may charge a fee if you've recently opted back in. Opting out doesn't change your NEM 3.0 status — you're still on the Solar Billing Plan regardless of which entity supplies your generation.

Does my CPA tier affect my solar export credit?

Yes, in part. CPA's share of your export credit is based on CPA's avoided generation cost, which varies slightly by tier and by the wholesale market conditions CPA faces. The difference between tiers is generally small on the export side — the bigger variable is time of day, not which tier you're on.

Is the Sun Storage Rebate stackable with other incentives?

CPA states the Sun Storage Rebate can be combined with other incentives where program rules allow. Since SGIP residential funding is waitlisted in 2026, the Sun Storage Rebate is largely the only active rebate in play for most CPA customers. Always confirm current stacking rules directly with CPA before signing a contract.

What happens to my CPA enrollment when I go solar?

Going solar doesn't change your CPA enrollment. You remain a CPA generation customer and an SCE delivery customer. Your solar system is interconnected through SCE, and your NEM 3.0 Solar Billing Plan account is administered by SCE — but CPA's generation charges and credits continue to appear on your bill.

How do I know if I'm in CPA territory or LADWP territory?

Look at the top of your electricity bill. It will clearly show either Southern California Edison or Los Angeles Department of Water and Power as your utility. If it says SCE and you live in a CPA member jurisdiction, you're a CPA customer. If it says LADWP, you are not — and NEM 3.0 does not apply to you.

Does CPA offer any solar incentives beyond the Sun Storage Rebate?

As of mid-2026, the Sun Storage Rebate is CPA's primary residential solar-adjacent incentive. CPA has offered community solar and income-qualified programs in the past; check cleanpoweralliance.org for current offerings. State-level programs like SGIP remain waitlisted for residential customers.
