The Southwest Power Pool (SPP) continues to experience significant supply issues due to high load levels and limited generator availability. SPP’s forecasts anticipate that due to high load and persistent cold weather, it is likely its system will fluctuate between Energy Emergency Alert (EEA) levels 1-3 over the next 48 hours (see below for explanation of EEA levels). Additional periods of load shedding are possible during this time.

Heartland Consumers Power District continues to request its wholesale power customers, and their associated retail customers, (Wessington Springs residents)  to voluntary conserve or limit energy usage as much as possible until further notice as a result of the EEA Alerts. Conservation measures will help maintain system reliability and integrity along with helping control electric costs for all consumers. Please do not apply any measures as a result of this alert that may put you or others personal safety at risk.

SPP declared an EEA Level 3 starting Tuesday morning at 6:15 a.m. The emergency alert means electric generation in the region is not sufficient to meet the extreme and widespread demand for electricity. SPP began temporarily shutting down power, otherwise known as rolling blackouts, in order to reduce demand on the system. Several utilities throughout the region were affected.

The shortage of electricity was caused by record low temperatures throughout the country.

SPP currently has enough generating capacity available to meet system-wide demand. As of 12:31 p.m. Central time SPP has downgraded the EEA to Level 1. This is declared when all available resources have been committed to meet obligations, and SPP is at risk of not meeting required operating reserves.

SPP previously declared a move from EEA Level 3 to EEA Level 2 at 11:30 a.m. Central time. 

SPP’s forecasts anticipate that due to high load and persistent cold weather, it is likely its system will fluctuate between EEA levels over the next 48 hours.

Examples of energy conservation include delaying or discontinuing use of appliances such as dishwashers and washing machines. Turn your thermostat down. Shut off unnecessary lights and discontinue use of space heaters.

Energy Emergency Alert Level 1: Declared when all available resources have been committed to meet obligations, and SPP is at risk of not meeting required operating reserves.

Energy Emergency Alert Level 2: Declared when SPP can no longer provide expected energy requirements and is an Energy Deficient Entity, or when SPP foresees or has implemented procedures up to, but excluding, interruption of firm load commitments.

Energy Emergency Alert Level 3: At this level, SPP is utilizing operating reserves such that it is carrying reserves below the required minimum and has initiated assistance through the Reserve Sharing Group. Declared when SPP foresees or has implemented firm load obligation interruption. Before requesting an EEA 3, SPP will have already provided the appropriate internal notifications to its Market Participants.
