TL;DR: The Customer Benefit Contribution (CBC) is a monthly charge on Con Edison bills for solar customers in New York. It funds grid maintenance and public benefits programs. Most residential solar owners pay between $5 and $15 per month. Understanding CBC helps set accurate expectations for solar ROI and long-term savings.

What Is the Customer Benefit Contribution?
The Customer Benefit Contribution (CBC) is a monthly surcharge applied to Con Edison customers who have distributed energy resources like rooftop solar panels. New York State introduced this charge as part of its Value of Distributed Energy Resources (VDER) framework, which replaced the older net energy metering (NEM) system starting in 2020.
The CBC exists because solar customers still rely on the electric grid for power at night, during cloudy weather, and during high-demand periods. Even when solar panels generate more electricity than a home consumes, that power flows through utility infrastructure. The charge covers a solar customer’s share of grid upkeep and public benefit programs that all ratepayers fund.
This is not a penalty for going solar. It is a cost-sharing mechanism designed to keep grid funding stable as more households generate their own electricity.
Why New York Created the CBC for Solar Customers
Before VDER, New York’s net metering system credited solar customers at the full retail rate for every kilowatt-hour exported to the grid. That worked well when solar adoption was low, but as installations grew, utilities argued that solar households were not paying their fair share of fixed grid costs.The New York Public Service Commission (PSC) agreed that a revised structure was needed. The result was the VDER tariff, which values exported solar energy based on multiple components:
- Energy value (wholesale electricity price)
- Capacity value (reducing peak demand)
- Environmental value (avoided carbon emissions)
- Demand reduction value (lowering infrastructure strain)
- Locational value (where on the grid the solar is connected)
The CBC was layered into VDER as a separate line item. It ensures that solar customers continue to support programs like low-income energy assistance, energy efficiency initiatives, and grid reliability investments that benefit every ratepayer in the service territory.
How the CBC Appears on a Con Edison Bill
The Customer Benefit Contribution shows up as its own line item on monthly Con Edison statements. It is separate from delivery charges, supply charges, and any VDER credits earned from exported solar energy.A typical Con Edison bill for a solar customer includes these sections:
- Supply charges for electricity drawn from the grid
- Delivery charges for moving power through Con Edison’s infrastructure
- VDER credits that offset charges based on solar energy exported
- Customer Benefit Contribution as a standalone monthly surcharge
- Taxes and other regulatory fees
The CBC amount does not fluctuate with energy usage the same way supply charges do. It is calculated based on the size of the solar system and the customer’s rate class. Some months the charge may be slightly higher or lower depending on adjustments, but it remains relatively predictable.
How Much Does the Customer Benefit Contribution Cost?
For most residential Con Edison solar customers in the Hudson Valley and greater New York area, the CBC falls between $5 and $15 per month. The exact amount depends on system size, rate schedule, and the specific VDER tariff that applies to the installation date.
Here is a general breakdown of what solar homeowners can expect:
Estimated Monthly CBC for Residential Con Edison Solar Customers
| System Size (kW) | Estimated Monthly CBC | Annual CBC Cost |
| 4 kW (small) | $4 – $7 | $48 – $84 |
| 7 kW (average) | $7 – $12 | $84 – $144 |
| 10 kW (large) | $10 – $16 | $120 – $192 |
| 12 kW+ (oversized) | $13 – $20 | $156 – $240 |
These figures are approximations based on published Con Edison rate schedules. Actual amounts vary by billing period and any PSC-approved rate adjustments. Commercial systems face higher CBC charges proportional to their larger capacity.
Compared to total monthly electric bills that can run $150 to $300+ before solar, the CBC represents a small fraction of overall costs. Most solar owners still save hundreds of dollars per year even after accounting for this charge.
How the CBC Affects Solar ROI Calculations
Any honest solar proposal should account for the CBC when projecting savings and payback periods. Ignoring it leads to inflated return estimates and disappointed customers.
Impact on Monthly Savings
A solar system that offsets $180 per month in electricity costs but carries a $10 CBC still delivers $170 in net monthly savings. Over a 25-year panel lifespan, that $10 monthly charge adds up to $3,000. For a system that saves $54,000 over the same period, the CBC reduces the total benefit by roughly 5.5%.
That is a real cost, but it does not fundamentally change the economics of going solar in New York. Federal tax credits (30% under the Inflation Reduction Act), NY-Sun incentives, and rising electricity rates still make solar a strong financial decision for most homeowners.
Adjusting Payback Period Estimates
A typical residential solar installation in the Hudson Valley costs $18,000 to $28,000 before incentives. After the federal tax credit and state rebates, the net cost drops to $10,000 to $18,000 for most homeowners.
Without the CBC, a system saving $170 per month pays for itself in about 7 years (on a $14,000 net cost). Adding a $10 monthly CBC extends that payback by roughly 4 to 6 months. The difference matters, but it is not a dealbreaker.
The key is making sure the solar proposal includes CBC in its financial model from the start. Reputable installers in the Hudson Valley already factor this into their quotes.
Does the CBC Apply to All New York Utilities or Just Con Edison?
The CBC is not exclusive to Con Edison. It applies across New York State under the VDER framework. Any utility operating under the New York PSC’s jurisdiction charges some form of CBC to distributed generation customers.
CBC Applicability Across Major New York Utilities
| Utility | Service Area | CBC Applies? | Notes |
| Con Edison | NYC, Westchester, southern Hudson Valley | Yes | Higher CBC due to dense urban grid |
| Central Hudson | Mid-Hudson Valley, Catskills | Yes | Moderate CBC rates |
| NYSEG | Southern Tier, Finger Lakes, eastern NY | Yes | Lower CBC for rural areas |
| National Grid | Capital Region, upstate NY | Yes | Standard VDER CBC structure |
| Orange & Rockland | Lower Hudson Valley, northern NJ | Yes | Similar to Con Edison structure |
| Rochester Gas & Electric | Greater Rochester area | Yes | Standard CBC under VDER |
The charge amounts and calculation methods differ between utilities because each has different rate structures and cost-of-service models. Con Edison’s CBC tends to be on the higher end due to the density and complexity of its service territory in the New York City metro area and southern Hudson Valley.
Customers served by municipal utilities or cooperatives (like the Long Island Power Authority, which operates under a different structure) may have different mechanisms. It is important to check with the specific utility provider.
VDER and the Bigger Picture for Solar in New York
The CBC is one piece of New York’s broader clean energy transition. The VDER framework replaced net metering to create a more market-based approach to valuing distributed solar. Under VDER, solar exports receive credits based on real-time energy value rather than a flat retail-rate credit.For solar owners, VDER means:
- Credits vary by time of day and season (exporting during peak afternoon hours earns more)
- The environmental and capacity components add value beyond just the energy price
- Credits are calculated monthly and applied to future bills
- The CBC is deducted as a fixed cost regardless of how much solar is exported
New York’s goal is 70% renewable electricity by 2030 and 10 GW of distributed solar by 2030. The state continues to offer strong incentives through the NY-Sun program, and the VDER structure is designed to scale as solar adoption grows.The CBC helps make that scaling sustainable by keeping grid funding intact even as more customers generate their own power.
Tips for Solar Owners to Minimize CBC Impact
While the CBC itself is a fixed regulatory charge that cannot be avoided, solar owners can take steps to maximize overall savings and offset its impact:
- Right-size the solar system. Oversizing a system does not eliminate the CBC but may generate excess credits that go unused. Work with an installer to match system output to actual consumption patterns.
- Add battery storage. A home battery like the Tesla Powerwall or Enphase IQ stores excess daytime solar for evening use, reducing grid dependence and maximizing self-consumption. This does not remove the CBC but reduces other grid charges.
- Shift energy usage to peak solar hours. Running appliances like dishwashers, laundry machines, and EV chargers during midday when panels produce the most power reduces the amount of grid electricity purchased.
- Monitor VDER credit statements. Reviewing monthly Con Edison statements helps identify whether credits are being applied correctly and whether usage patterns could be optimized.
- Lock in current rates. Solar installations that interconnect sooner may benefit from current VDER rates before any future PSC adjustments. Delaying installation risks changes to the rate structure.
- Claim all available incentives. The 30% federal Investment Tax Credit, NY-Sun rebates, and any local incentives reduce the upfront cost, improving ROI even with the CBC factored in.

Frequently Asked Questions
Q: What is the Customer Benefit Contribution on a Con Edison bill?
A: The Customer Benefit Contribution (CBC) is a monthly surcharge for solar and distributed energy customers. It covers the solar customer’s share of grid maintenance, public benefit programs, and low-income energy assistance that all ratepayers fund. It appears as a separate line item on Con Edison bills.
Q: How much is the CBC for residential solar customers?
A: Most residential Con Edison solar customers pay between $5 and $15 per month for the CBC. The exact amount depends on the size of the solar system and the applicable rate schedule. Larger systems face slightly higher charges.
Q: Can solar customers avoid paying the Customer Benefit Contribution?
A: No. The CBC is a mandatory regulatory charge under New York’s VDER framework. All grid-connected distributed generation customers pay it. Going off-grid entirely would eliminate the charge, but that is impractical for most homes and removes access to VDER credits and grid backup.
Q: Does the CBC make solar not worth it in New York?
A: The CBC reduces savings by a small amount, but solar remains a strong investment in New York. The federal 30% tax credit, NY-Sun rebates, and rising electricity rates mean that most homeowners still achieve payback within 6 to 9 years. The CBC adds a few months to that timeline at most.
Q: Is the CBC the same as a solar tax?
A: No. The CBC is not a tax. It is a utility surcharge approved by the New York Public Service Commission. The revenue stays with the utility and funds grid infrastructure and public benefit programs. It is part of the VDER tariff structure, not a government tax.
Q: Will the Customer Benefit Contribution increase over time?
A: The CBC rate is set by the New York PSC and can be adjusted during utility rate cases. Rates may increase or decrease depending on grid costs and policy changes. Solar owners should review annual rate case decisions to stay informed about any adjustments.
