State Grid Modernization Policy Q2 2026: Find Your State
NC Clean Energy Technology Center counted 47 interconnection-rule actions in Q2 2026. Why that count matters to equipment buyers and how to find your state's.
State grid modernization policy moved fast in Q2 2026. The NC Clean Energy Technology Center (NCCETC) counted 481 grid modernization actions in the quarter, across 44 states plus the District of Columbia and Puerto Rico, on top of more than 300 introduced bills.
For a distribution equipment buyer, a different number in the same release matters more: 47 of those actions concerned interconnection rules. Only energy storage deployment proposals (63) drew more.
This post explains why an interconnection-rule change reaches your bill of materials, and gives you a method for finding what your own state did. We are not publishing a state-by-state list. NCCETC sells the full breakdown as a paid report, we have not read it, and a list inferred from the free summary would be a guess.
What the Q2 2026 state grid modernization report says
Everything below comes from NCCETC’s own July 22, 2026 release for the Q2 2026 edition of The 50 States of Grid Modernization.
The most frequent action types, in NCCETC’s order:
| Action type | Q2 2026 actions |
|---|---|
| Energy storage deployment proposals | 63 |
| Interconnection rules | 47 |
| Overall utility business model reforms | 46 |
| Performance-based energy storage incentives | 35 |
| Performance-based regulation | 32 |
| Smart grid technology deployment | 29 |
California, Maryland, Virginia and New Jersey saw the most action, followed by Illinois, New Mexico, Louisiana and New York. That ordering is an activity count. It does not tell you which states approved a plan, and it should not be read that way.
The release names three trends: utilities pursuing location-based incentives for distributed energy resources, policymakers scrutinizing utility spending on infrastructure upgrades, and states facilitating virtual power plant participation in wholesale markets. Its top five developments were Minnesota regulators approving Xcel Energy’s first-of-its-kind virtual power plant program, the Maryland Public Service Commission approving virtual power plant programs, California regulators beginning a review of advanced electric rate design, Virginia lawmakers enacting a flurry of new grid modernization laws, and the North Carolina Utilities Commission approving dynamic line rating prototypes.
Two quotes in the release are worth keeping straight. Nick Montoni, Senior Program Director at NCCETC, said: “We’re seeing a continued trend towards increased scrutiny on utility investments.” Autumn Proudlove, Managing Director of Policy and Markets, said: “Increasingly, location-based incentives are being incorporated into utility programs to encourage targeted deployment of distributed energy resources where the grid can benefit the most.”
These are Q2 figures. NCCETC publishes quarterly, so a Q3 edition will replace them. The method in this post does not depend on which quarter you are reading.
Why interconnection rules reach your equipment spec
An interconnection rule is where a state decides the terms on which solar, storage and other distributed resources connect to a utility’s distribution system. Depending on the state, that can include the application screens a project must pass, study timelines, who pays for system upgrades, and which technical standard an inverter must meet. The national standard for interconnecting distributed energy resources is IEEE 1547-2018, and a rule that adopts or updates it changes what connecting equipment has to do.
Each of those terms has a hardware consequence on one side of the meter or the other:
- Technical standard and settings. When a state updates the inverter standard or the required settings, the equipment an interconnecting customer can buy changes, and the utility’s own voltage regulation and protection settings may need to be revisited to work with it.
- Protection and disconnect requirements. Rules that change what protection a project must carry, or how the utility isolates it, change the relaying and switching specified at the point of interconnection.
- Metering. Rules that let aggregated resources participate in programs or markets tend to arrive with metering requirements. Our read of CAISO’s DER metering reform shows how a market rule becomes a metering question.
- Upgrade cost allocation. Who pays for a transformer or feeder upgrade triggered by an interconnection decides whether the cost lands on the utility’s rate base or on the developer. The utility usually still specifies and buys the equipment, but the funding source can change when the order is placed.
We are not saying each of the 47 actions changed a spec. Many will be proposals, comment rounds or procedural orders. The point is narrower: this is one of the categories of state policy with the shortest path to a technical requirement, so it is worth checking first.
How to find where your state landed
You can do this with free, public sources.
- Find the proceeding. Search your public utility commission’s docket system for open proceedings with “interconnection,” “distributed generation,” “DER,” or “grid modernization” in the title. If your commission publishes a rulemaking calendar, check it too.
- Read the latest order, not the press release. Commission press releases describe intent. The order says what is required, of whom, and by when.
- Find the compliance filing. Look for any direction to the utility to file revised tariffs, interconnection procedures or a technical requirements manual by a date. That filing is usually where a policy turns into a spec: settings tables, protection requirements, metering configurations.
- Note the effective date. It tells you when interconnecting customers and your own engineering standards have to reflect the change, which is the date that should drive any related order.
- Check your own utility’s technical manual. If you are a municipal utility or co-op outside commission jurisdiction for this purpose, your governing board or state association may adopt its own version. Compare it to the state rule so you know where you differ.
If you want the state-by-state list rather than doing the search, NCCETC offers a free, email-gated executive summary and sells the full quarterly report through its site.
What this means for buyers
The Q2 count is a reason to look, not a forecast. What it tells a municipal or cooperative buyer is that interconnection rules drew the second-largest share of state grid modernization actions in Q2 2026, and that the compliance filing behind any one of them can change what you need to stock and specify for customer-owned generation.
Three things are worth doing now. Put your state’s open interconnection proceeding on a watch list. Ask your engineering lead whether your technical requirements manual still matches the current state rule. And treat compliance-filing dates as procurement inputs, because they are when the specification actually moves.

Frequently Asked Questions
How many states took grid modernization actions in Q2 2026?
The NC Clean Energy Technology Center reports that 44 states, as well as the District of Columbia and Puerto Rico, took grid modernization actions in Q2 2026, for a total of 481 actions plus more than 300 introduced bills.
How many Q2 2026 actions involved interconnection rules?
47, according to the NC Clean Energy Technology Center's Q2 2026 edition of The 50 States of Grid Modernization. Only energy storage deployment proposals (63) drew more actions.
How do I find out what my state did?
Search your public utility commission's docket system for the open interconnection or grid modernization proceeding, read the most recent order, and find the compliance filing it requires. The compliance filing is usually where a policy becomes a technical requirement.
