StatusApproved Last reviewed 2026-10-14
Applies atExpected monthly demand of 20 MW or more and an expected load factor above 80%
What the filing saysAPPROVED by the IID Board on September 15, 2026 (a public power utility, not regulated by the California PUC). New or expanded loads that meet the threshold must take service under Schedule LL and go through a studied queue; applying does not reserve capacity or a queue position. Initial contract term of at least 15 years (set in the Electric Service Agreement), then continuing until ended; either party must give at least 60 months' written notice to end or change service. Exit fee equals the remaining Minimum Charge for any terminated or reduced capacity for the rest of the initial term. Service deposit of at least 3 months of demand and minimum charges, normally in cash, in addition to other collateral required by the agreement. The customer funds the studies.
