NV Energy interconnection requirements
Sample preview — compiled from public sources 2026-08-19
Who this applies to
This page covers customer-sited generating and storage systems — solar, energy storage devices (ESDs), and solar-plus-storage — interconnecting in parallel with NV Energy's distribution system in Nevada under the customer generation framework the Legislature set in Assembly Bill 405 (2017) and the Public Utilities Commission of Nevada (PUCN) administers.
- Residential and small commercial solar, 25 kW or less — the typical rooftop case; new systems default to the NMR-405 Tier 4 net metering rate.
- Systems larger than 25 kW up to 1 MW AC — net metered under the NMR-B rate; projects over 25 kW also route through NV Energy's engineering review.
- Energy storage — stand-alone storage and storage paired with solar both apply through the same portal, with storage-specific documentation (technical specs, Interconnection Agreement Attachment B).
- Both service territories — Northern Nevada and Southern Nevada follow the same handbook, with different application fees and, for Northern Nevada applications approved on or after October 1, 2025, a 15-minute netting billing structure.
Systems over 1 MW AC (up to 20 MW) are outside the net metering program and are handled by NV Energy's Rule 15 interconnection team; transmission-level projects are out of scope for this page.
Application pathway overview
All net metering and energy storage interconnection applications go through NV Energy's PowerClerk portal. The application is considered incomplete until the application fee — required under NV Energy's Rule 15 tariff — is received and processed; if the fee doesn't arrive within 30 days of submission, the application is cancelled.
Once the fee posts, the application moves through a fixed sequence of review statuses. Application Review, Engineering Review (typically for projects larger than 25 kW or non-standard designs), and Metering Technical Review all run inside the same first ten-business-day window. Deficiencies at any point route the project into a corrections status with a 60-calendar-day deadline. After approval, the applicant uploads final documentation — including the local jurisdiction's final inspection card — and Documentation Review plus routing into NV Energy's utility inspection queue happen within a second ten-business-day window. Permission to Operate (PTO) is emailed after the safety inspection passes and required meters are set.
| Pathway | Typical projects | Review |
|---|---|---|
| Net metering — NMR-405 Tier 4 | Solar and solar-plus-storage, 25 kW or less | Application Review + Metering Technical Review; Engineering Review only if non-standard |
| Net metering — NMR-B | Systems over 25 kW up to 1 MW AC | Includes Engineering Review inside the first ten-business-day window |
| Energy storage only | Stand-alone ESDs; battery additions to existing systems | Same portal and statuses, storage documentation required; adding storage alone does not change the net metering rate |
| Over 1 MW AC | Large projects up to 20 MW | Outside net metering — coordinate with NV Energy's Rule 15 team |
Required forms & documents
The structural contents of an NV Energy net metering / storage packet, per the current interconnection handbook. Which items apply depends on configuration (solar only, solar-plus-storage, storage only) and on property ownership; check the handbook's current revision before filing.
- Interconnection application in PowerClerk, tied to the correct NV Energy account holder, premise number, and installation address
- Application fee payment (check with application number, or electronically via Paymentus)
- Site plan — installation address, location of panels, ESDs, inverters, disconnects, meters, main panel and sub-panels, access issues noted, contractor name and license number
- Electrical one-line (or three-line) diagram — all on-site electrical systems including existing generation and storage, technical specs, contractor name and license number
- Energy storage technical specifications — nameplate energy capacity, maximum charge and discharge power (storage applications)
- Fully executed Interconnection Agreement — all parties matching PowerClerk, all pages, Attachment B if storage is installed
- Final inspection card and/or satisfied building permit from the local jurisdiction (permit copy plus passed-inspection results)
- Proof of property ownership, or a fully executed Property Transfer Agreement (PTA) when the host customer is not the owner of record
- Signed third-party contract when the property is rented, confirming the property owner authorizes the installation
- Engineering calculation stamped by a Nevada-licensed PE, energy audit, or livable-square-footage sizing when the account lacks 12 months of billing history
- UL recertification report or manufacturer approval if the customer's electrical bus bar was modified
Fees
NV Energy charges a flat, non-refundable initial review fee for every net metering application, set under its Rule 15 tariff and differing by service territory. The fee is paid outside PowerClerk (mailed check or Paymentus) but the application cannot advance until it posts.
| Item | Published amount | Notes |
|---|---|---|
| Initial review fee — Northern Nevada | $184 verify current schedule | Per NV Energy's interconnection handbook; Rule 15 tariff |
| Initial review fee — Southern Nevada | $189 verify current schedule | Per NV Energy's interconnection handbook; Rule 15 tariff |
| Grid upgrades required to pass inspection | verify current schedule | The handbook makes the customer responsible for the cost of any upgrades needed to pass inspection |
If the fee is not received within 30 days of submission, the application is cancelled. Duplicate payments for the same application are returned; cash is not accepted.

Typical timeline stages
- Submission and fee — application in PowerClerk; fee must post within 30 days or the application is cancelled.
- First review window (10 business days) — Application Review confirms host customer, address, and system data; Engineering Review (projects over 25 kW or non-standard designs) and Metering Technical Review run inside the same window.
- Corrections, if flagged — deficiencies route the project to a corrections status; review restarts on resubmission, and corrections not submitted within 60 calendar days cancel the application.
- Installation and final documentation — after approval, build the system, pass the local jurisdiction's final inspection, and upload the inspection card with the signed Interconnection Agreement (and PTA if required).
- Second review window (10 business days) — Documentation Review confirms the as-built details, then the project moves into NV Energy's inspection queue within the same window.
- Utility inspection and PTO — NV Energy's metering team performs the Interconnection Safety Verification and sets required meters; the Permission to Operate email follows a passing inspection. Systems may not be energized before final verification.
Common deficiency causes
Common ways NV Energy applications fall short of the published requirements above — each item is a requirement in NV Energy's own handbook and application checklist whose absence triggers a correction cycle. Not drawn from SunDocket filing data.
- Addresses that don't match across the application, the utility bill, the county assessor's record, the site plan, and the one-line diagram
- System or storage sizes, or inverter counts, that differ between the application and the one-line diagram
- Host customer who is not the property owner of record, without the proof-of-ownership documentation or an executed Property Transfer Agreement
- Rented property without the property owner's signed third-party contract
- Accounts with less than 12 months of billing history filed without a PE-stamped engineering calculation, energy audit, or square-footage sizing basis
- Equipment not on the CEC approved-equipment lists, missing UL listing, or inverters not IEEE 1547 compliant
- Interconnection Agreement missing pages, signatures, or Attachment B on storage projects
- Permit copy uploaded without the separate passed-inspection results attached
- Fee not received within 30 days of submission, or corrections not returned within the 60-calendar-day window — both cancel the application
FAQ
How long does NV Energy interconnection take?
NV Energy's handbook structures review in two ten-business-day windows: Application Review, Engineering Review (if required), and Metering Technical Review share the first ten business days after the fee is paid, and Documentation Review plus routing into the inspection queue happen within a second ten business days after final documents are uploaded. Corrections restart the relevant review, so total calendar time depends mostly on how clean the packet is and on the local jurisdiction's inspection date.
What is the NV Energy interconnection application fee?
NV Energy's handbook lists an initial review fee per application of $184 in Northern Nevada and $189 in Southern Nevada, required under its Rule 15 tariff — verify current schedule before filing. The application is considered incomplete until the fee is paid, and it is cancelled if the fee is not received within 30 days of submission.
What is NMR-405 Tier 4?
NMR-405 is Nevada's net metering rate established under Assembly Bill 405 (2017). It stepped down in tiers as capacity milestones were reached: 95%, 88%, and 81% tiers are closed, and Tier 4 — the open, default tier for new systems of 25 kW or less — credits excess energy at 75% of the retail rate. Per the PUCN, the rate is locked for 20 years at the installation location.
What portal does NV Energy use for interconnection applications?
PowerClerk. All net metering and energy storage interconnection applications are submitted through NV Energy's PowerClerk portal, which generates the application number, produces agreements for signature, and tracks the application through each review status.
Can I turn my system on before NV Energy's inspection?
No. NV Energy's handbook states systems may not be energized prior to successful final verification, and the customer does not receive kWh credit for exported energy until NV Energy's meters are set. Permission to Operate is emailed after the utility safety inspection passes and required meters are installed.
What is the size limit for net metering with NV Energy?
Net metering is capped at 1 MW AC. Systems of 25 kW or less default to the NMR-405 Tier 4 rate; systems larger than 25 kW and up to 1 MW default to the NMR-B rate. Projects above 1 MW are handled outside the net metering program through NV Energy's Rule 15 interconnection team.
What changed for Northern Nevada solar customers in October 2025?
Per NV Energy's handbook, Northern Nevada customers whose net metering applications are approved on or after October 1, 2025 are billed under a 15-minute netting structure: delivered and exported energy are netted in 15-minute intervals, and net excess energy in an interval is valued at 75% of the applicable retail rate. Existing customers remain on monthly netting.
