Analyzing Rate Impacts of Various DSM Program Designs by Dave Lamont

This study evaluates the rate impacts of different DSM program designs, based on revenues and sales data from 2004. The analysis includes adjustments for losses attributed to sales, VELCO impacts, and base load forecasts post-2008. Revenue adjustments are made for contract expirations and market purchases, with inflation escalation. The model incorporates ICF avoided cost studies and DSM budget scenarios, leading to increased rates and decreased revenue requirements.

  1. Rate Impacts of Various DSMProgram Designs Dave Lamont EEU Budget Negotiations April 10, 2006

  2. Model Design • Based on 2004 revenues and sales • Losses attributed to Sales and DSM impacts are adjusted to VELCO • Base load forecast assumes no new DSM after 2008 • Base load growth (no DSM) assumed to be 1.5%

  3. Model Design • 2004 Base revenues separated into VY, HQ, and IPP plus “everything else” • Revenues are adjusted going forward for impacts of contract expirations as well as incremental market purchases and sales. “Everything else” escalated at inflation (2.5%) • Model used ICF avoided cost study, including ICAP cost projections

  4. Model Design • RR includes DSM budgets for ‘06 – ’08 • Revenue requirements (RR) adjusted for T&D expenditures above base peak load

  5. Scenarios • Model used DSM scenarios as presented by EVT at the 12/3/2005 workshop • A second set was developed which assumed 2008 savings levels continued through 2025 with costs escalated at inflation (2.5%) • Savings estimates incorporated EVT decay function • DSM costs expensed in each year

  6. Results • Rates increased • Revenue requirements (including DSM costs) decreased

  7. Base Case
