Delaware Adopts Consolidated Billing for Community Solar: What Senate Bill 321 Changes

Community solar subscribers in Delaware have had to do their own math to see what they were actually saving. One bill arrived from Delmarva Power. A separate invoice arrived from the subscription coordinator, listing the credit, the fee, and the net result. Reconciling the two required a spreadsheet, or at least a working trust that the numbers lined up.

That friction is gone. Governor Matt Meyer signed Senate Bill 321 into law today, making net crediting the required consolidated billing methodology for Delmarva Power and Light. Community solar subscribers will now see one bill, from one utility, with one number that reflects what their subscription actually saved them. The change lands as Delaware's community solar program continues to expand, giving subscribers, landowners, and developers a clearer view of how a fast-growing market actually pays out.

What Senate Bill 321 Changes

SB 321 amends Title 26 of the Delaware Code to move community solar billing from a two-invoice model to a single, utility-issued bill. Instead of separately collecting a subscription fee, Delmarva nets that fee against the subscriber's solar credit and reports the net result directly on the customer's regular utility bill.

The bill, sponsored by Sen. Stephanie Hansen along with Reps. Heffernan and Burns, also sets a floor under subscriber economics. As passed, it guarantees a minimum 10% discount off what a customer would otherwise pay Delmarva, net of fees, rising to 20% for low- and moderate-income subscribers. The legislation also accounts for the administrative and information-technology costs Delmarva may incur in building the new billing infrastructure, treating consolidated billing as a system that has to be built correctly rather than a simple policy switch.

How Does Net Crediting Work?

Under net crediting, Delmarva sets up a third-party account on behalf of each community solar subscriber. The utility handles physical billing only. It nets the subscription charge against the monthly credit, then aggregates and pays out the resulting subscription revenue to the coordinator, without absorbing the underlying cost or collection risk itself.

This is not an untested model for Delmarva. The same consolidated billing approach already runs in Atlantic City Electric's territory and in Pepco and Delmarva's Maryland jurisdictions. Delaware is not asking its utility to build something new so much as extend a system it already operates elsewhere, which is part of why the bill frames net crediting as the lower-risk option for Delmarva's broader customer base.

Why This Raises the Value of Delaware Community Solar Projects

A subscriber who has to reconcile two invoices to find their savings is a subscriber more likely to question the value of the subscription, or drop it before the project has recovered its acquisition cost. A subscriber who sees one net number on one familiar bill captures that value proposition in the time it takes to open the mail.

That distinction is commercial, not just administrative.

Lower subscriber churn supports steadier subscription revenue. Steadier revenue underwrites more confident pricing at the front end of a project, the kind of pricing that improves returns for landowners and strengthens project economics for developers. A single, familiar bill format also tends to reduce the subscriber-service burden that comes with billing confusion: fewer calls asking why a credit looks smaller than expected, fewer disputes over a fee a subscriber does not remember agreeing to. That is its own form of value, showing up in lower administrative overhead well before it shows up in retention numbers.

Delaware already supports more than 15 active or approved community solar projects representing over 60 megawatts of capacity, and consolidated billing gives that pipeline a materially easier product to sell to the next subscriber.

What Does This Mean for Delaware Landowners and Developers?

For a Delaware community solar developer, SB 321 removes a genuine friction point from customer acquisition without touching the underlying economics of a project. ECA Power operates a community solar development platform built on land held across Delaware, including a completed 6 MW community solar project in Hartly and a partnership expanding community solar across Delaware. Projects like these depend on subscriber enrollment holding steady for the life of the asset, and a simpler bill is one more input that supports that.

For landowners weighing whether their acreage fits a community solar project, the state's underlying signal has not changed, only sharpened. Delaware has spent the past year accelerating permitting for community solar even as it addressed the billing experience, which suggests a state intent on growing this market rather than just tolerating it.

The Takeaway

SB 321 does not change what makes a community solar project perform over 20 or 25 years: a sound interconnection, a credible offtake structure, and disciplined asset management. What it changes is how clearly a subscriber can see the result of that work every month.

For a market that depends on subscriber trust as much as favorable economics, that clarity carries its own commercial weight.

ECA Power continues to develop community solar projects across Delaware, and landowners evaluating a lease now have one more reason to expect a program that is easier to explain and easier to trust.
