The New York PSC has adopted tariff changes at KeySpan New York and KeySpan Long Island (National Grid) to improve capacity release for ESCOs, and other previously adopted retail market enhancements may now be implemented on a permanent basis as KeySpan's new Gas Transportation Information System (GTIS) has gone live

These changes include the physical release of storage assets, the additional release of capacity assets related to this storage, and imbalance calculations adopted in an October 2014 order

Specifically, with regard to capacity release, the PSC approved tariffs that permit the KeySpan LDCs to implement changes to core monthly balanced transportation. The revisions will implement Tier 2A – Storage Capacity Release and provide the transfer of gas inventory that remains in storage to marketers at the LDCs' weighted average storage inventory price.

The PSC noted that with this change, ESCOs will now receive a significant portion of the storage transportation capacity previously withheld. These changes will allow ESCOs to source and transport natural gas closer to the way the LDCs purchase gas for their sales customers.

The LDCs' existing retail access storage service, which bundles storage capacity with inventory, Tier 2B – Retail Access Storage, will continue to be provided to marketers in lieu of a physical capacity release of storage assets that are not releasable.

The revisions will also effectuate a weather true-up adjustment each day to account for any differences between actual and forecasted weather on each Marketer’s daily delivery quantity. The weather true-up adjustment will be applied to each Marketer’s available Tier 2B Retail Access Storage inventory balance.

The LDCs had noted that testing has identified a lingering interface problem between the GTIS and the existing customer support systems used by both companies. The LDCs indicate that this problem generates about 1,000 exceptions per month out of 310,000 monthly transactions. The problem identified will be handled on a manual basis going forward until a final fix is in place. According to the LDCs, this issue could take up to 4 months to rectify.

In light of this issue, the PSC required the LDCs to file monthly reports on any exceptions
