Edison International

Edison’s core asset is Southern California Edison, a state‑regulated T&D monopoly. Efficient‑scale and regulatory franchise provide the primary moat, with very high switching costs because customers cannot economically bypass the incumbent grid. Intangibles include the franchise, permits, and operating know‑how across 50,000 square miles.

Cost advantages come from scale in capital deployment and procurement. Network effects are minimal in a wires‑only business. Component scores and weights: efficient scale 90 (weight 40%), switching costs 90 (25%), regulatory/intangibles 80 (20%), cost advantages 60 (10%), network effects 20 (5%).

Weighted moat score is 78. Durability is supported by CPUC’s multi‑year GRC and cost‑of‑capital decisions and by long‑dated capex to serve electrification and data‑center load.

Moat erosion risks are concentrated in policy or legal changes that could heighten wildfire cost exposure or restrict recovery, plus distributed generation and customer migration to CCAs. The AB 1054 framework and safety certification reduce but do not eliminate tail risk.
