What it is
A professional engineer argues that NYC building electrification projects fail economically when envelope improvements are skipped. Electrical upgrades to support heating loads cost $54K per apartment—more than the heat pumps themselves—while operating costs rise due to high electricity rates and grid strain from winter peak demand.
Why it matters
Facility owners and public housing authorities face a retrofit cost/scope tradeoff: undersized electrical infrastructure becomes the primary bottleneck and cost driver in heat pump deployments. The $54K per-apartment electrical upgrade figure directly impacts project feasibility, financing decisions, and whether electrification delivers positive ROI or increases operating expense.
Evidence from source:
- Window heat pump project costs $54K per apartment, with electrical upgrades costing more than the heat pumps themselves
- By 2035 NYC will have a winter peaking grid; every kW of additional heating demand requires new generation and transmission capacity
- Heat pump-only retrofits often increase operating costs, giving negative return on investment due to big electrical loads and higher electricity rates vs. natural gas
