Hourly (real-time) pricing

Some utilities bill a price that changes every hour with the wholesale market instead of a fixed rate or time-of-use windows. SolDial supports these plans natively — starting with ComEd Hourly Pricing — watching the live price for you and acting on it.

What an hourly plan is

On ComEd’s Hourly Pricing program (also called residential real-time pricing, BESH or RRTP), you pay the market’s hourly average price for supply. Overnight and on windy days power is often very cheap — sometimes near zero — while hot summer evenings can spike far above a flat rate. That volatility is exactly what a Powerwall is built for: fill up when power is cheap, run the house on battery when it isn’t.

Setting it up

In Settings → Utility Rates, choose the Hourly plan type and pick your provider — that’s the whole setup. There are no windows or prices to enter: SolDial fills in your utility and plan and pulls the price live from then on. If you look your plan up by zip code and pick an hourly plan like BESH, SolDial recognizes it and switches you to Hourly automatically.

Today’s prices on your dashboard

Hourly users get a dashboard section named after their plan. It shows the price right now (color-coded cheap → expensive, with a rising/falling arrow), a curve of today’s actual prices from midnight up to this hour, and today’s low, average, and high — so “is now a good time to run the dryer or charge the car?” is a one-glance answer. These are real prices from ComEd’s own feed, never estimates.

Automations on the live price

The electricity price trigger works on your live price: fire when it rises above or drops below a threshold you set. Classic hourly-plan rules look like “below 3¢/kWh → charge the Powerwall from the grid” or “above 15¢/kWh → raise self-consumption and ride the battery.” SolDial reacts to a threshold crossing typically within a minute, and your rules’ thresholds are drawn right on the dashboard price curve so you can see where they’ll bite. Grid charging only ever happens if you’ve allowed it in Export & grid-charging permissions, and all the usual guards — backup-reserve floor, cooldowns — still apply. See Building your own automations.

Autopilot understands hourly plans

Energy Autopilot and Suggestions know an hourly plan has no fixed peak window. Instead of scheduling around clock times, they build price-threshold strategies around your Energy Goals — charging into genuinely cheap hours and holding the battery for expensive ones.

Prices shown are ComEd’s hourly supply price in ¢/kWh — delivery charges on your bill are separate. ComEd Hourly Pricing is the first supported program, with more hourly programs on the way. On a flat or time-of-use plan instead? See Setting up your rate plan.
