Electrical Stage Alerts

Learn how to prepare for the 3 possible stages of electrical alerts.
Electricity alerts are possible during warm summer weather. The California Independent Systems Operator (ISO) and San Diego Gas & Electric (SDG&E) issue alerts through a 3-stage warning system, and UCSD will relay any warnings to the campus community.
- ISO System Conditions: See today's outlook.
- To receive instant energy alert notifications, subscribe to the "electricalstagealerts-l" mailing list.
Note: UCSD and Facilities Management have no control over statewide electrical emergencies. These emergencies are defined and controlled by the ISO and SDG&E.
Learn about what each stage means and the appropriate actions to take:
Note: If the ISO issues a rolling blackout, UCSD will receive only a 15-minute or shorter warning from SDG&E. Therefore, your actions during Stage 1 and Stage 2 alerts are crucial.
Stage 1 — Voluntary load reduction:
A shortfall in the electricity operating reserve is unavoidable or will likely occur within 2 hours.
- What you should do: Turn off all unnecessary lights and equipment (such as fans, coffee machines, microwaves). If possible, do not start sensitive work.
Stage 2 — Forced load reduction:
A serious shortfall in the operating reserve (bringing it to less than 5% of normal levels) is unavoidable or will likely occur within 2 hours. (UCSD will engage a global load-shedding program to reduce air-conditioning loads in non-critical areas.)
- What you should do: Save and secure all sensitive work immediately. (You may not receive sufficient notice between Stage 2 and Stage 3 alerts.)
Stage 3 — Blackout is imminent:
A critical shortfall in the operating reserve (bringing it to less than 1½% of normal levels) is unavoidable or will likely occur within 2 hours. Without significant ISO intervention, the electric system could collapse. Rolling blackouts will occur as required to keep the operating reserve above 1½%. Again, if the ISO issues a rolling blackout, UCSD will receive only a 15-minute or shorter warning from SDG&E.
- What you should do: Save and secure all sensitive work — this is your last chance to do so. Reduce electricity consumption wherever possible.
