LIPA Solar Overview
Long Island Power Authority (LIPA) is a municipal utility that owns the electric transmission and distribution system on Long Island. While LIPA owns the infrastructure, PSEG Long Island operates the system day-to-day under a management contract. For solar customers, this means dealing with PSEG Long Island for interconnection and billing.
Service area: Nassau & Suffolk Counties, NY
Customers: 1.1 million
Average rate: ~$0.22/kWh (among highest in US)
Net metering: Available with good terms
Solar rating: ★★★★★ (Excellent) (Source: EIA Electric Power Monthly)
Long Island's combination of high electricity rates, good net metering, and New York State incentives makes it one of the most attractive solar markets in the country. Payback periods of 9-12 years are common, and many homeowners see significant savings from day one with financing.
Net Metering Policy
LIPA Net Metering Program
LIPA offers net metering that credits excess solar production at close to retail rates. New York's Value of Distributed Energy Resources (VDER) has evolved, but residential solar on Long Island still benefits from favorable compensation:
| Feature | LIPA Policy | Impact |
|---|---|---|
| Export compensation | Near retail rate | High value for excess production |
| Credit rollover | Monthly with annual true-up | Winter credits used in summer |
| System size limit | 25 kW residential | Adequate for most homes |
| Interconnection | Through PSEG Long Island | Established process |
VDER vs Traditional Net Metering
New York has transitioned to Value of Distributed Energy Resources (VDER) for new solar projects. On Long Island, residential solar customers still receive favorable compensation, though the exact rate depends on when your system was interconnected and your specific rate class.
LIPA Electric Rates
Current Rate Structure
LIPA/PSEG Long Island rates are among the highest in the continental US:
| Component | Typical Rate | Notes |
|---|---|---|
| Supply charge | ~$0.10-0.12/kWh | Energy generation cost |
| Delivery charge | ~$0.08-0.10/kWh | Transmission/distribution |
| Taxes & surcharges | ~$0.02-0.03/kWh | Various fees |
| Total | ~$0.20-0.25/kWh | Varies by usage tier |
Why Rates Are So High
- Island geography: Infrastructure costs higher
- Limited generation: Much power imported via underwater cables
- Storm exposure: Coastal location = maintenance costs
- High demand: Dense population, summer AC loads
- Legacy costs: Shoreham nuclear plant shutdown debt
New York Incentives
State and Local Programs
New York offers strong solar incentives that apply to LIPA customers:
| Incentive | Value | Notes |
|---|---|---|
| NY State Tax Credit | 25% (up to $5,000) | In addition to federal credit |
| NYSERDA Incentive | Varies by block | Installer applies on your behalf |
| Property Tax Exemption | 100% for 15 years | Solar doesn't increase property taxes |
| Sales Tax Exemption | 8% savings | No sales tax on solar equipment |
Solar Economics
Typical System Economics on Long Island
| Factor | Long Island (LIPA) | National Average |

Why Payback is Faster on Long Island
- Higher electric rates: Each kWh worth more
- Good net metering: Excess valued fairly
- State incentives: 25% state credit helps
- Rising rates: LIPA rates increase over time
- High property values: Solar adds home value
2026 Federal Tax Credit
PPA/Lease: The Section 48E credit (30%) remains available through December 31, 2027. The solar company claims the credit and passes savings to you through lower payments. (Source: IRS guidelines and DSIRE Database)
Impact on Long Island Solar
The loss of the federal credit for purchased systems impacts Long Island less than many markets because:
- High rates still drive savings: $0.22/kWh creates value even without federal credit
- NY State credit remains: 25% state credit (up to $5,000) still available
- Tax exemptions intact: Property and sales tax exemptions still apply
- PPA/Lease option: Still benefits from 30% through 2027
| Option | Federal Credit | NY State Credit | Best For |
|---|---|---|---|
| Cash purchase | None (expired) | 25% up to $5,000 | Long-term ownership |
| Solar loan | None (expired) | 25% up to $5,000 | No upfront cost + ownership |
| PPA/Lease | 30% (through 2027) | N/A (company claims) | Immediate savings, lower payments |
Interconnection Process
PSEG Long Island Process
| Step | Timeline | Notes |
|---|---|---|
| Application | Day 1 | Installer submits to PSEG LI |
| Utility review | 10-20 days | Technical review |
| Approval to install | 5-10 days | Authorization issued |
| Installation | 1-2 days | Physical install |
| Town inspection | 5-15 days | Local building dept |

Tips for LIPA Customers
Do This:
- Act on high rates: Every month you wait, you pay $0.22/kWh

Frequently Asked Questions
Does LIPA have net metering?
Yes, LIPA (through PSEG Long Island) offers net metering with favorable compensation for excess solar production. New York's VDER framework applies, but residential customers still receive good value for exports.
What is the difference between LIPA and PSEG Long Island?
LIPA (Long Island Power Authority) owns the electric infrastructure. PSEG Long Island operates the system under a management contract. For solar customers, you'll interact with PSEG Long Island for interconnection, billing, and service.
Why are LIPA rates so high?
Long Island's island geography, infrastructure costs, storm exposure, imported power via underwater cables, and legacy costs (like the Shoreham nuclear plant) all contribute to higher rates. The flip side: these high rates make solar extremely attractive.
What is the payback period on Long Island?
Typical payback for purchased systems is 9-12 years, even without the federal credit. This is faster than the national average due to high electricity rates (~$0.22/kWh) and the NY State 25% tax credit.
Can I get the federal tax credit on Long Island?
For purchased systems, the federal 30% credit (Section 25D) expired December 31, 2025. For PPA/Lease agreements, the Section 48E credit (30%) remains through 2027. The NY State 25% credit (up to $5,000) is still available for all qualifying systems.
Is solar worth it on Long Island?
Absolutely. Long Island is one of the best solar markets in the country due to high electricity rates, good net metering, and strong state incentives. Even without the federal credit for purchased systems, payback periods remain attractive.
