The short version: the Regulated Rate Option (RRO) was Alberta\'s default electricity rate from the early 2000s through 2024. It passed wholesale price movements through to monthly bills with a short delay. After the 2022 to 2023 price spikes, the AUC and the province redesigned it. The Rate of Last Resort (RoLR) replaced it in 2025, with a longer purchasing window and built-in smoothing. Same job, different mechanism, fewer surprises.

The belief that drove the original RRO design

When the RRO was designed, the assumption was that a thin pass-through formula was best — markets work, so households should see the market signal. If the wholesale price was low, RRO should be low. If wholesale was high, RRO should be high. Discipline through transparency. It worked in stable years and failed catastrophically when volatility arrived.

Why this matters for the rate-shopping decision

Under RRO, the case for signing a fixed contract was driven by the fear of next month\'s pool-price spike. Under RoLR, that fear is largely gone — the default is doing some of the hedging for you. The reason to sign a fixed contract today is more about your individual risk tolerance and your view on the multi-year forward curve, not about avoiding next month\'s shock.

That changes the math. Where RRO made an aggressive case for fixed contracts during 2022, RoLR removes a chunk of that urgency. The decision is more deliberate and less reactive.

What this means for your household

  • If you were on the RRO before the reform, you are on RoLR now. Same retailer, smoother formula.
  • The fixed-contract pitch that worked in 2022 ("avoid the spike") is less compelling under RoLR.
  • Your bill will still move month to month with the seasons and with delivery-rider changes, but the wild swings should be much rarer.
  • If a salesperson tells you "RoLR is risky", ask them to define risky against a real comparison window — not against the worst single month of 2022.

Frequently asked questions

The transition from the Regulated Rate Option (RRO) to the Rate of Last Resort (RoLR) took effect in 2025, following an AUC decision and provincial regulatory updates. The new framework was phased in across all service areas with default-supplier arrangements.
If you were on the RRO before the change, your default supplier rolled you onto RoLR automatically. Your retailer did not change, just the rate formula did. If you were on a fixed contract, nothing changed.
The 2022 to 2023 price spikes exposed a structural problem: the RRO formula passed wholesale volatility straight through to monthly bills, which neither the AUC nor the government considered acceptable for a default rate. A formula tweak would not have fixed the underlying short procurement window.
Not directly. The change altered how price moves over time, not the long-run average. In a market with high forward prices, RoLR is still high. The benefit is fewer monthly shocks, not a structural discount.
It is possible. The AUC reviews default-rate design periodically. If a future market environment exposes a different problem with RoLR, another reform could happen. The current framework is the response to the specific problems of 2022 and 2023.
