AI summary

Exhibit E-8-(i) Appendix B presents a side-by-side comparison of the Efficiencyone Plan and the NSPI Alternative Plan across 14 end-use categories (residential, commercial, and industrial) for each of 2016, 2017, and 2018, plus a 2016–2018 aggregate.
The EfficiencyOne Plan projects total three-year program costs (including enabling strategies) of approximately $121.5 million against ~405,929 MWh of savings, while the NSPI Alternative Plan targets ~$65.5 million against ~278,246 MWh — roughly 46% lower cost and 31% fewer MWh.
Key divergences centre on RES-HVAC/Shell, RES-Lighting, RES-Water Heat, RES-Package, and COM-HVAC, where the NSPI Alternative Plan proposes zero or sharply reduced spending; for example, NSPI caps RES-HVAC/Shell at $1.2 million/year (vs. EfficiencyOne's ~$4.9–$8.2 million/year) and eliminates RES-Lighting entirely.
On a first-year unit cost basis, the NSPI Alternative Plan is consistently cheaper (~$240–$248/MWh) than the EfficiencyOne Plan (~$290–$313/MWh) across all three years, yielding a three-year blended unit cost of ~$235/MWh vs. ~$299/MWh.
Sheet 2 shows that the NSPI Alternative Plan would deliver approximately 33,842 kW of cumulative incremental peak demand savings over 2016–2018, compared to 62,456 kW under the EfficiencyOne Plan, with the gap driven almost entirely by the residential HVAC/Shell and lighting categories where NSPI proposes minimal or no activity.
