Just like the old folk song, June has been a good month for demand response (DR) from California to the New York Island. First, the California Independent System Operator (CAISO) released a proposal to allow aggregated distributed resources to bid into its markets, potentially as early as next year. Then, the New York Public Service Commission (NYPSC) approved all of the plans of the state’s utilities (aside from Consolidated Edison [ConEd]) to commence DR programs this summer. The programs are modeled on ConEd’s existing suite of DR programs.
CAISO found a way to introduce a new acronym, distributed energy resource provider, or DERP, into the industry lexicon. The proposal lays out a framework for allowing aggregated resources of at least 500 kW to participate in the market. There is also a requirement that any aggregations serving more than a single grid pricing point must be limited to a single type of technology. Metering has been one of the hurdles to DR participating in CAISO markets because the system requires generation-scale monitoring. The new rules would allow DR to be aggregated via the Internet, providing for a broader range of resources to be brought to market with less cost. DERP aggregators will be a scheduling coordinator metered entity, which will avoid “having each sub-resource in a DERP aggregation engaged in a direct metering arrangement with the CAISO,” according to the proposal. Access to ancillary markets, however, will still require resources to allow constant monitoring by CAISO. CAISO’s board is set to consider the proposal in July, but would need approval from the Federal Energy Regulatory Commission (FERC) before it can move ahead with the plan.
Meanwhile, in New York …
A week later across the country, NYPSC gave the green light for the upstate investor-owned utilities to follow ConEd’s lead and offer distribution-level DR programs to their customers starting this summer, a very quick turnaround time. This order is one of the early wins of New York’s Reforming the Energy Vision proceeding to transform the utility model in the state. The programs have three basic types: a peak shaving program to be called on a day-ahead basis when demand is expected to hit the summer peak; a local distribution reliability program to be called on as needed for localized issues; and a direct-load control program that lets customers install a device that can be controlled by utilities to control loads to compensate for system stress. Customers can take part in the programs individually or through an aggregator. This summer, the utilities are prioritizing areas that offer the greatest benefits at the lowest costs, based on factors including system stress and local distribution constraints for the year. All of the DR programs will be available starting next summer.
So, while the DR community continues to wait for the Supreme Court’s ruling on FERC Order 745 on DR compensation, the states are pushing the DR agenda ahead rather than waiting for direction from the feds.
