3.8.2 Wind p. p. 18
3.8.2 Wind - Wind generation resources performed well during the event. Hourly average wind generation - and forecasts are shown in the following table. DATE FILED: March 6, 2026 Page 19 of 23

AI summary The document notes that wind generation resources performed well during a specific event, with hourly average wind generation and forecasts presented in a table. The text was filed on March 6, 2026, as part of a regulatory proceeding.

Preamble p. p. 19
- 4 steeper generation decline than the two-day-ahead planning forecast on January 23 as shown on - 5 the graph below, with the actual wind generation dropping by 367 MW between the first and last - 6 hour of the day due to declining wind...

AI summary The text discusses a significant drop in wind generation on January 25, 2026, with a 367 MW decline over the course of the day due to reduced wind speeds. This variability in wind generation highlights the need for dispatchable generation to meet peak energy demands, especially when wind output is low.

AI summary During a cold-weather event from January 23-26, 2026, wind generation dropped significantly due to decreasing wind speeds. There were no operational issues with the wind turbines, and the low production was attributed to low wind conditions rather than turbine performance issues.

Section 28 p. p. 28
Request IR-16: Page 20 of 23, Figures 11 and 12 provide hourly average wind generation and forecasts. (a) Please confirm whether the generation forecast was adjusted for cold weather. (i) If not, please provide Figure 11 and Figure 12 with...

AI summary The response to Request IR-16 explains that a temperature-adjusted generation forecast was not prepared for the January 2026 event, as temperatures were not expected to drop below -15°C. However, NS Power reconstructed a forecast based on available weather data, noting that some wind farms may experience reduced output in extreme cold.
