Powerwall settings for LADWP R-1B, honestly

R-1B in plain English: LADWP’s standard residential time-of-use schedule.

Not every TOU plan is an arbitrage goldmine. R-1B’s winter spread is a couple of cents — the strategy here is seasonal, and pretending otherwise wastes battery cycles.

The plan at a glance

R-1B varies by zone and season; winter rates shown from a real Los Angeles configuration. Rates come from the published tariff as reflected in SolDial's rate database in mid-2026 — always verify current numbers with your utility.

What this plan means for a Powerwall

Here’s the honest version you won’t find on most blogs: in winter, R-1B’s periods differ by only a cent or two. Cycling a battery hard for a 1.5¢ spread earns almost nothing and spends the pack’s life doing it — the math many apps happily invent doesn’t exist here. Winter strategy: Self-Powered with a healthy reserve, take the solar self-consumption savings (those are real at 22¢+ retail), and keep the pack ready for outages.

Summer is a different plan wearing the same name: high-peak afternoon rates open a real spread, and Time-Based Control starts paying. The right answer changes with the calendar — which is precisely the kind of seasonal switching a human forgets and an automation doesn’t.

The automations worth having

A seasonal mode switch; a summer pre-peak hold; storm watch; and honest expectations — SolDial’s savings estimates are computed from your actual windows, and where the spread is thin it will tell you so instead of promising invented dollars.

Does this apply to my exact situation?

Plans vary by zone, season, and enrollment vintage, and utilities revise rates. SolDial matches your account to the actual published schedule from ~50,000 tariffs and recomputes the strategy — and the honest savings math — from your windows, not a blog’s snapshot. If your plan differs from this page, the app follows your plan.
