Ferc_ let fast-start resources set prices _ rto insider

The commission said new rules are required to allow fast-start resources to set LMPs — changes regulators said should reduce uplift and provide more accurate price signals to encourage investments.

“Without some form of fast-start pricing, most fast-start resources are not eligible to set prices even when they are the marginal resource,” Daniel Kheloussi, a staffer in FERC’s Office of Energy Policy and Innovation, said during a presentation at the commission’s monthly meeting. Electricity review worksheet “Further, even when fast-start resources can set prices, they may not be able to recover their commitment costs, such as start-up and no-load costs, through prices. Gas jobs pittsburgh As a result, prices may not reflect the marginal cost of serving load.”

The commission said fast-start resources are unique because they are often dispatched to inflexible minimum or maximum operating limits, making them ineligible to set LMPs. Electricity invented what year They also are usually committed in real-time.

“As a result, the cost to commit these resources is incurred at roughly the same time the incremental energy costs are incurred, which raises the question of whether the commitment costs should be included in the LMP,” the commission said. Gas after eating red meat “Finally, fast-start resources can arguably respond quickly enough to be considered part of an RTO’s/ISO’s operating reserves even when they have not yet been committed.”

• Standardize the definition of fast-start resources to include any resource committed by the RTO/ISO that is able to start up within 10 minutes or less, has a minimum run time of one hour or less and that submits economic energy offers to the market. Gas natural inc The definition would be technology-agnostic.

• Require that an RTO must incorporate the start-up and no-load costs (commitment costs) of a committed resource in energy and operating reserve prices for the resource’s minimum run time.

• Require RTOs to relax the resource’s economic minimum operating limit (eco min) when calculating prices — treating it as if it is dispatchable from zero to the economic maximum operating limit (eco max).

The NOPR is the third issued by the commission since it initiated a proceeding on price formation in RTO/ISO markets in June 2014 (AD14-14).

Because the system may not need all of the resource’s eco min to meet load, other resources must be dispatched down, making them the most economic option to serve the next increment of load. Gas zombies black ops “Therefore, despite the fact that a fast-start resource is essentially marginal, this restriction prevents a fast-start resource dispatched at its economic minimum operating limit from setting the LMP,” the commission said.

Thus, some RTOs have relaxed the resources’ eco min limits, treating them as dispatchable in a pricing algorithm separate from the dispatch algorithm. Gas bloating back pain But while these changes can improve price signals — especially during stressed conditions when the need for fast-start resources is the greatest — the disconnect between prices and dispatch instructions can cause over-generation.

In comments filed following the commission’s technical workshops on price formation, many stakeholders said they would support changes allowing resources dispatched at their operating limits to set LMP and allowing start-up and no-load costs to affect prices. Gas definition science The Electric Power Supply Association and Western Power Trading Forum said such changes could help address CAISO’s “duck curve” by redistributing excess costs incurred during the middle of the day to the ramping periods. 1 unit electricity cost in tamilnadu Region

The commenters noted that start-up time requirements for quick-start resources range from 10 minutes in NYISO, MISO and SPP, to 30 minutes in ISO-NE and two hours in PJM and CAISO.

Several stakeholders praised MISO’s extended LMP.

NYISO and ISO-NE also received some praise, while Golden Spread Electric Cooperative criticized SPP, saying the RTO’s market design and operator practices fail to reflect fast-start resources’ costs and their value to the system.

NYISO worked with its Market Monitoring Unit and stakeholders on revising its “hybrid gas turbine pricing logic,” resulting in a Dec.

SPP said it will be implementing fast-start pricing to commit quick-start resources more efficiently in real time in the second quarter of 2017.

PJM was criticized by its Independent Market Monitor, which said that relaxing eco mins for price setting is subjective and overrides “fundamental pricing logic,” sometimes increasing total production costs.
