10 Other Issues AB1X Residential Rate Cap SCE is continuing its efforts in both regulatory and legislative arenas to find a reasonable solution to the residential rate cap problem Absent a change the forecast differential between upper and lower tier rates is not sustainable GHG Reduction Costs Prior to rules being established, carbon prices being known or reasonably predictable, and allowance allocations being finalized, it is difficult to determine these costs and their impacts on SCE rates A command and control approach resulting in substantial acceleration of renewable procurement and other costly measures (e.g., forced divestiture of coal assets/contracts) could have significant impact on SCE s rates A market-based approach with a reasonable allocation of allowances will minimize the impact on SCE s rates 10
