Visual Primer: Texas Power Outages Draw Scrutiny into Grid Operator’s Market Design and Reliability

The widespread power outages across Texas during the extreme winter weather conditions brought about by a polar vortex in mid-February has raised questions about the reliability of the power grid operated by the Electric Reliability Council of Texas Inc. (ERCOT). The grid operator, which manages about 90 percent of the state’s electric load, reported that 48.6 percent of generation was forced out at the highest point due to the winter storm.

Visual Primer: FERC Order on PJM Capacity Market Reforms Hinders States’ Plans for Clean Energy Transition

The Federal Energy Regulatory Commission has issued an order on implementing reforms that expand the minimum offer price rule (MOPR) to most state-subsidized resources participating in the regional capacity market administered by PJM Interconnection LLC, which operates across 13 states and the District of Columbia. The ruling has sparked concerns over its potential to harm renewable generation seeking to participate in the capacity market and frustrate state clean energy policies.

EnerKnol’s Visual Primer – New England Grid Operator Proposes Market-Based Solution to Energy Security Challenges

The New England grid operator has proposed a long-term, market-based solution to the region’s energy security problem as the power generation fleet moves towards a mix of energy-limited resources. With the retirement of resources with stored fuel, the system is increasingly reliant on facilities that run on just-in-time natural gas deliveries and weather-dependent wind and solar energy. To address the ensuing challenge, the grid operator proposes to improve the current market structure by creating incentives for the region’s fleet to invest in the energy supply arrangements and technologies on which the region depends.

PJM Files Price Formation Reforms for Proper Valuation of Energy Reserves

PJM Interconnection LLC on March 29 filed a proposal with the Federal Energy Regulatory Commission to revise its energy and reserve market rules to properly value the energy reserves that support grid reliability by providing the flexibility needed to accommodate the evolving resource mix. The grid operator said that the growing variability of power demand…...

Natural Gas Dethrones Coal in Nation’s Largest Wholesale Electricity Market

Natural gas accounted for nearly 31 percent of power generation in PJM Interconnection LLC’s footprint in 2018, surpassing coal’s share of about 29 percent, according to a March 18 report from the grid operator’s market monitor. Nuclear power dominated the region’s generating sector representing about 34 percent of the generation mix last year. Renewables had…...

FERC Drops Case Against Footprint Power for Alleged False Supply Offers in New England Power Market

The Federal Energy Regulatory Commission on Feb. 25 ended its investigation into allegations that Footprint Power LLC made false and misleading power supply commitments in the summer of 2013 for its natural gas-fired Salem Harbor Power Plant in Salem, Massachusetts. The move follows the Office of Enforcement’s recommendation that the commission vacate its order to…...

New England Grid’s Reliability Risks to Crop Up Year-Round With Shift to Gas, Renewables

New England’s grid is undergoing a rapid change as nuclear, oil, and coal-fired power plants that operate with stored fuel are retiring in larger numbers, and are being replaced by natural-gas-fired plants and renewable generation. Natural gas accounted for 49 percent of the region’s power generation last year, up from just 15 percent in 2000…....

New England’s Evolving Resource Mix Makes Power System Operations More Complex: ISO-NE Report

New England’s power system is strong, but the changing resource mix, driven by industry trends and state policies, is making operations more complex, according to a Feb. 20 briefing on the state of the region’s grid by Gordon van Welie, president and CEO of ISO New England Inc. Nuclear, oil, and coal-fired power plants that…...

California Grid Operator Forms Oversight Committee to Advance Reliability Coordinator Services

The California Independent System Operator Corporation on Feb. 20 announced that its reliability coordinator service, named RC West, established an oversight committee to “provide guidance and foster consensus on reliability compliance.” RC West has completed 39 service agreements with balancing authorities and transmission operators across the west. The ISO announced last month that it is…...
