2020–2021 Winter Reliability Assessment

ATLANTA - November 18, 2020 – In its 2020–2021 Winter Reliability Assessment, NERC finds sufficient resource capacity is in place across North America to meet winter demand. Noting how extreme weather can challenge grid reliability in specific areas, the assessment closely examines this reliability risk and identifies higher risk areas that susceptible to emergency operating actions.

During extreme and prolonged winter conditions, vital natural-gas fuel supplies for electricity generation can be at risk in New England, California and the southwestern United States. High reliance on natural gas-fired generation and limited natural gas infrastructure elevates reliability risk in these areas.

For this assessment, NERC analyzed severe weather scenarios that incorporated generation outages under peak load conditions. NERC noted particular reliability risk in areas within the Midcontinent Independent System Operator, the Canadian Maritimes, Texas, the Rocky Mountain Reserve Group and the Northwest Power Pool.

“Winter conditions challenge grid operators in many parts of North America. Our assessment looks at expected peak demand and the ability of the area resource mix to provide that demand under harsh winter conditions,” said Mark Olson, manager of Reliability Assessments. “Overall, industry takes winter reliability risks very seriously. Our extreme weather scenarios help stakeholders prepare for situations where winter conditions threaten resource adequacy, potentially forcing grid operators into emergency actions like demand curtailment.”

As the COVID-19 pandemic continues, NERC also stresses a priority focus on protecting the workforce, including system and power plant operators. This year’s assessment highlights the below key findings for the upcoming winter season: 

Sufficient capacity resources are expected to be in service.

• Fuel and energy assurance risk remains a reliability concern.

• Extreme weather continues to pose risk to bulk power system reliability.

• The ongoing pandemic is causing increased uncertainty in electricity demand projections and presents cyber security and operating risks.

• Post-2020 hurricane season restoration efforts may continue in hard-hit areas along the Gulf

Coast, where storm damage has degraded the transmission system that supplies local areas.

Undertaken annually in coordination with the Regional Entities, NERC’s Winter Reliability Assessment examines multiple factors that collectively provide deep and unique insights into reliability risk. These factors include resource adequacy, encompassing reserve margins and scenarios to identify operational risk; fuel assurance; and preparations to mitigate reliability concerns. The report encourages industry to discuss their plans and preparations to ensure reliability for the upcoming winter period.

Black & Veatch: No More Coal Construction

by ronfluegge 5. November 2020 12:31

Black & Veatch is ending the company’s participation in coal-based power market design and construction, saying it will allow the company to focus on clean energy technologies. The engineering and construction giant’s announcement Oct. 29 comes just more than a month after another major energy company, General Electric, said it would exit the new-build coal power market.
