Below, affected ISO customers can learn more about changes to systems or procedures related to the Market Enhancements for DARD Pumps (MEP) Project. This project was one of several that ISO New England has undertaken, in collaboration with stakeholders, for the continued development of the region’s wholesale electricity markets.
See Participant Readiness Project Outlook for more detail on specifically affected customers and systems for this and other major projects.
Project implemented: 03/01/17
ISO New England encouraged pump storage hydro-generating resources to move to economic bidding and away from self-scheduling options by introducing new modeling practices and bidding parameters for dispatchable-asset-related demand (DARD). These bidding parameters include the ability to specify a maximum daily consumption limit and maximum number of daily starts for use in the day-ahead market schedule and to view the minimum-run time and minimum-down time values in order to optimize real-time dispatch solutions. Day-ahead and Real-time Net Commitment-Period Compensation (NCPC) settlements were modified to include NCPC payment calculations for DARD pumps, including NCPC dispatch lost opportunity cost.
This project was schedule to be released concurrently with the Subhourly Settlements (SHS) Project and Real-Time Fast-Start Pricing (FSP) Project.
Affected market participants were required to take specific steps or adapt to changes in ISO Systems, as described below and should be mindful of additional time-bound items, some of which may require customers to take specific steps or adapt to changes in ISO systems after the project implementation date.

eMarket Data Exchange Specification v.10.4 |
These guides were provided with the eMarket sandbox release and include instructions on how to submit Max Daily Consumption and Max Daily Number of Starts for DARD pumps in eMarket in support of the project. Web services documents were provided for customers familiar with XML, web services, and HTTP/HTTPS protocols to aid in developing interfaces to exchange meter reading data. |
