AI summary The SBA comments on the CPP rate, highlighting a 10:1 ratio for winter rates. NS Power responds that while the temporary suspension of on-peak and critical peak rates during the 2025/26 Season may seem like a discount, the impact on CPP customers is substantial. NS Power notes that only 8 to 14 of 18 possible critical peak events have occurred over the past four years, and the program's impact is relatively small.
