The arbitrage arithmetic, done properly
Spread is the difference between on-peak and off-peak. Take the mid-spread, multiply by the usable kWh of the battery, then by realistic cycles a year — 250 to 300, not 365. That is the gross annual arbitrage value. Compare it against the marginal cost of the battery over its warranty term before you let a salesperson call storage an investment.
On this rate the mid-spread is roughly $0.17 per kWh. On a 13.5 kWh battery at 275 cycles a year that is about $650 a year, gross, before round-trip losses and before you account for the fact that you cannot arbitrage a battery you are also holding in reserve for outages.
Solar
What this rate does to solar economics
Summer afternoon production aligns with the on-peak window. This is the most favorable solar-plus-TOU combination in the state.
Show the arithmetic
A household using 10,000 kWh a year on Rate 180 (Time-of-Day option) pays roughly $2,450 for energy at the $0.24/kWh midpoint, plus $204 in basic service charges. A 100% offset removes the $2,450 and leaves the $204.
Midpoint arithmetic for illustration. Your all-in rate depends on your supply arrangement and the season.
Storage
What this rate does to battery economics
A usable arbitrage spread, second only to Con Edison's. Pair it with the outage case and Long Island is the one part of New York where storage economics are genuinely defensible on more than one axis.
Watch out
Catches on this rate
- Off-peak EV charging and a battery compete for the same overnight window — do not double-count the savings.
- Confirm which LIPA net-metering vintage you fall under before modeling exports.
Interconnection
Getting connected on PSEG-LI
- LIPA, not the Public Service Commission, sets the rules here. Net-metering terms, successor tariffs, and any customer contribution charge are decided separately from the six investor-owned utilities — so statewide guidance you read elsewhere may simply not apply.
- Long Island's wind-load requirements drive heavier racking and more attachment points than an upstate roof needs. That is a real line-item cost difference, not installer padding.
- The most saturated residential solar market in the state. Quote-to-quote price spread on identical hardware is the widest anywhere in New York.
Application to Permission to Operate

Utility-side only. Permitting and install scheduling are on top.

How this page is built
This is a generated page: the structure is shared across locations, the numbers are not. Every figure comes from the source cited beside it, with the date we last checked it. Nothing here is a quote, an appraisal, or tax advice, and none of it is specific to your roof.
Rates and incentive programs change. We re-verify utility tariffs and NYSERDA program status on a rolling schedule and stamp the date on each number rather than on the page, so you can see which specific figures are fresh. Full methodology · Program status tracker · About the Local Energy Playbook
