Earthjustice filed a grievance with FERC on behalf of SEIA difficult a MISO rule that prohibits renewable power assets from offering ancillary providers.
Earthjustice, an environmental legislation group, filed a grievance with the Federal Power Regulatory Fee (FERC) on behalf of the Photo voltaic Power Industries Affiliation (SEIA), difficult a rule that prohibits renewables from offering ancillary that service. The rule was initiated by grid operator Midcontinent Impartial System Operator (MISO) in 2011 and has by no means been challenged.
With this rule, MISO is the one FERC jurisdictional grid operator that expressly prohibits wind, photo voltaic, and battery hybrid assets from offering ancillary providers, Earthjustice studies. Ancillary providers assist grid operators preserve a dependable electrical energy system, steadiness provide and demand, guarantee reliability throughout extreme climate occasions, and assist the system get better after an outage. within the energy system. Permitting wind, photo voltaic and battery hybrid assets, generally known as dispatchable intermittent assets, to be certified to supply ancillary providers will decrease general system prices, and make the grid extra dependable and secure. -on excessive climate and local weather disasters.
The grievance alleges that MISO’s practices prohibit dispatchable intermittent assets (DIR) equivalent to photo voltaic, wind and battery assets, from taking part in MISO’s ancillary providers market. The grievance claims that the ban “excludes DIRs from the chance to supply sure ancillary providers – together with regulatory providers, spinning reserves, and supplemental reserves – even supposing DIRS has the potential within the operation of offering such providers”.
Earthjustice mentioned within the grievance that MISO is alone on this “clearly discriminatory ban,” as a result of different FERC regional transmission organizations (RTOs) or impartial system operators (ISOs) have discovered that wind and photo voltaic assets are eligible. to supply these providers. Lastly, these tariff provisions could lead to “pointless and dangerous market limitations”.
The Criticism requests two major actions:
- That the Fee finds that the provisions of the MISO Tariff and enterprise practices are guide protocols that prohibit wind, photo voltaic, and battery hybrid assets from offering the ancillary providers that they’re technically able to to supply unfair, unreasonable, and extreme discrimination or desire pursuant to the FPA; and
- The Fee ordered MISO to revise the present ancillary service Tariff provisions and enterprise practices guide to permit wind, photo voltaic and battery hybrid assets to be eligible to take part in ancillary providers in MISO’s wholesale market. The Fee ought to direct that MISO’s Tariff and enterprise practices guide be reformed in a expertise impartial method so that every one technical assets able to offering the assorted service merchandise beneath the Tariff are allowed to supply of these merchandise.
MISO serves 45 million individuals in 15 states and the Canadian province of Manitoba, with a reported $40 billion in annual transactions. The quantity of power produced from wind and photo voltaic is predicted to extend considerably within the MISO area within the coming years, all of which have confirmed able to offering ancillary providers, in response to Earthjustice.
“Regional transmission authorities shouldn’t limit the providers that renewables can present,” mentioned Aaron Stemplewicz, senior lawyer at Earthjustice. “Any backsliding can be strongly challenged relating to the eligibility of renewable assets to supply all of the providers they’re able to present,” he mentioned.
“For the previous decade, MISO has discriminated towards renewable mills, and it is time for FERC to set the file straight and provides renewables a good shot,” mentioned Melissa Alfano, director of power markets and counsel at Photo voltaic Power Industries Affiliation (SEIA). “The truth is that the grid is altering and the power markets must sustain. Renewable belongings like photo voltaic, storage and wind have greater than confirmed themselves dependable, and we want acknowledge the complete scope of their advantages if we wish to quickly decarbonize.
MISO additionally plans to file a request with FERC to take away ramp functionality eligibility for renewable assets as effectively. Ramp functionality refers back to the means of an influence system to shortly enhance or lower its output to accommodate adjustments in energy demand. Ramp shortages are the most typical reason behind short-term shortages and worth spikes.
Stemplewicz mentioned Earthjustice may also problem any try to strip wind, photo voltaic and battery hybrid assets from ramping capability.
