Utility Reports 50% Use Of Direct ISO Market Purchases Would Have Saved $11 Million Over 2H 2024 Through 1H 2025; Contrasts With $11 Million Higher Charge From Self-Supply During 2H 2025
The following story is brought free of charge to readers by VertexOne, the exclusive EDI provider of EnergyChoiceMatters.com
At the direction of the New Hampshire PUC, Public Service of New Hampshire has provided counter-factual estimates of savings which would have occurred under small customer default service if 50% of small customer SOS had been served by direct ISO New England market purchases (self-supply) in the second half of 2024, and the first half of 2025, rather than the lower percentages of self-supply actually used during those periods
For the second half of 2024, in which actual self-supply was only 12.5% of small customer SOS load, PSNH estimated that 50% self-supply would have resulted in $10 million in aggregate savings versus 100% full requirements, compared to the $2.6 million in savings experienced under 12.5% self-supply
For the first half of 2025, in which actual self-supply was only 30% of small customer SOS load, PSNH estimated that 50% self-supply would have resulted in $1.4 million in savings versus 100% full requirements, compared to the $935,000 in savings experienced under 30% self-supply
Notably, this projected net $1.4 million in savings does reflect the impact of a $13 million reconciliation charge that would have been required under 50% self-supply, to the extent the original proxy price used at the time was used
The analysis had been requested by the PUC after PSNH data showed that, for the second half of 2025, small customer SOS ended up costing $11 million more under 50% self-supply than if 100% full requirements had been used, based on the average rate of forgone bids.
For the period January 2026 through May 2026, self-supply has saved $11 million versus 100% full requirements, based on the last-rejected full requirements bids
Looking at the actual amount of self-supply used for the entire period of the second half of 2024 through May 2026, during which the amount of self-supply varied, the actually-used self supply percentages, in aggregate, saved $3 million over this entire period, per PSNH data
Had 50% self-supply been used for the entire period of the second half of 2024 through May 2026, self-supply would have saved $11 million in aggregate, per PSNH data
