How to Leverage Cost Allocation to Enable Rapid, Affordable, and Equitable Electrification

The report analyzes cost allocation strategies for distribution grid investments driven by the electrification of buildings and transportation and the growth of distributed energy resources. It compares three state-level approaches—Minnesota's standardized fees, Massachusetts's Proactive Hosting Capacity Fee, and New York's project-level justification—while outlining the trade-offs between uniform, incremental, traditional, and proactive cost allocation models.

• Public utility commissions in Minnesota, Massachusetts, and New York have adopted distinct strategies for allocating the costs of grid upgrades: Minnesota uses standardized cost-sharing fees for large loads and DER developers with potential cost caps; Massachusetts is piloting a Proactive Hosting Capacity Fee with rate-impact caps and non-wires alternative considerations; and New York requires utilities to justify allocation choices on a project-by-project basis.
• Regulators can choose between uniform cost allocation, which is simple but may socialize costs among non-beneficiaries, and incremental cost allocation, which assigns costs to the specific customer class causing the need but may require complex metering and limit benefits to small segments.
• The timing of cost recovery differs between traditional investment cost allocation, which is straightforward but can lead to piecemeal investment and delayed electrification, and proactive investment cost allocation, which supports policy mandates and future load growth but relies on forecasting and may raise fairness concerns if growth does not occur.
