The situation
Your starting point
Take charge of an import-dependent utility in 2022. A small local fleet of gas, solar, wind and battery storage works alongside the northern intertie that helps keep customers supplied.
The scenario gives you advance warning of a severe import restriction in early 2025. This is a fictional utility set in Los Angeles, giving you a focused way to explore what happens when a major supply route fails.
The choices
What will you do?
-
Know what the connection provides
Check how much imported power you use in difficult hours. Available local capacity may look very different once the northern route is restricted.
-
Build another way to supply customers
Compare local construction, storage and other connections. Complete the work before the outage rather than counting on equipment still being built.
-
Test the plan through the day
Look beyond the sunny hours. The local fleet has to keep working when solar output falls and the usual imports are largely unavailable.
Put your plan to the test
A reliable connection is useful. Having a plan for losing it is useful too.
Build, watch what happens, and try a different approach. The grid is yours to run.
