Commission recap 10-27-2020: COVID-19 and weather impact on power used in the county

Weather and COVID-19 impacted expected power use this year, according to a presentation by Grant PUD economist Bob Brill given to PUD commissioners on Tuesday, Oct. 27.

Most customer rate classes saw significant differences between forecasted load for power and actual demand through the third quarter of this year. The initial forecasted load for the whole Grant County power system was 642 megawatts (MW), the actual load was 608 MW.

While the overall load was lower, residential customers saw its actual load increase by 7.2% above initial forecasted demand. Brill stated that growth of overall residential customers in the county and the increased numbers of hours that people are staying in their homes are two of the main reasons for that growth.

Irrigation customers also had significantly higher than expected power use this year, up 35.6%. Weather seemed to be the most significant factor as stated by Brill, with less rain and higher winds than normal weather.

Most commercial and industrial rate categories saw less demand for power, as shutdowns and economic slowdowns related to COVID-19 affected local businesses and industries, he added.

Less power sales in the county are offset by increases in wholesale power prices that have more than doubled since July in both the heavy-load hours and light-load hours, Brill stated.

Power Delivery looking at performance of grid sections in Grant County

Grant PUD Power Delivery is presently conducting a study to determine how best to improve sections of the local power grid that are underperforming based on a metric called Customer Average Interruption Duration Index (CAIDI). Grant PUD's system CAIDI goal is less than 110 minutes.

The utility came close to achieving this goal in August when it reached 120 minutes based on a 12-month rolling average, stated Jeff Grizzel, Managing Director of Power Delivery, in his presentation to the commission, but high winds and rain created a spike in prolonged outages in September.

To help achieve CAIDI goals in the future, Grizzel said his department is looking at the performance of each of the "feeder" sections of the power system and determining what changes need to be made to improve the worst-performing feeders.

Areas with the worst-performing feeders include Warden, Mattawa, Moses Lake, Grand Coulee, Potholes and Beverly.

Grizzel said he expects to have a final improvement plan to share with the commissioners in the first quarter of 2021.
