Time-of-Use pricing is not a theory problem. It’s a math problem.
In high-spread markets like California, peak electricity rates regularly hit $0.68–$0.74 per kWh, while off-peak power sits closer to $0.21–$0.25. That’s a 200–300% price gap for the same electricity, just at a different hour.
Here’s what that means in real dollars.
Take a commercial site using 500 kWh during peak hours per day.
Peak cost:
500 × $0.70 = $350 per day
If that same energy is shifted to off-peak and stored:
500 × $0.23 = $115 per day
Daily difference: $235
Annualized: roughly $85,000 per year in avoided energy cost.
That spread is why batteries and on-site energy systems are not “green add-ons.” They are arbitrage machines created by utility pricing.
This is where companies like NехtNRG and other power storage providers fit in. The value is not just having storage or generation on-site. It’s having a system that automatically charges when power is cheap and discharges when utilities penalize you the most. No guessing and no manual intervention.
As TOU pricing expands across more states and peak windows keep getting more expensive, this kind of setup stops being optional. It becomes a cost-control requirement.
Watch TOU spreads. That’s where the demand signal really comes from.
