What is a key responsibility regarding "Weathervaning" in Transmission Operations?

A key responsibility regarding "Weathervaning" in Transmission Operations is adjusting operational plans in response to weather-related impacts on transmission demand and generation. This concept involves monitoring weather conditions and their effects on the electrical grid, enabling operators to anticipate changes in both generation (such as decreased output from renewable sources during cloudy or windy weather) and demand (like increased heating during cold spells). By proactively adjusting operational plans, operators can ensure system reliability and prevent overloads or shortages as conditions change.

The other options, while related to operational considerations, do not directly align with the specific function of weathervaning. Enhancing the aesthetics of transmission lines, performing maintenance during bad weather, and increasing transmission capacity in anticipation of adverse weather focus more on peripheral activities rather than the core responsibility of adapting operations in real-time to meet the demands and limitations posed by varying weather conditions.
