The head of the Department for Fuel and Energy Sector Victoria Gimadi told a Rossiyskaya Gazeta correspondent about how attempts to cool down a room in hot weather may result in blackouts.
A blackout may occur if electricity consumption peaks because of heat
“In terms of imbalance between supply and demand a blackout
may result if electricity consumption peaks during hot weather when people turn
on all their air conditioners and fans,” Ms. Gimadi explained. She estimates
this may happen in regions that do not have sufficient power generation
reserves to meet such peaks in demand. As an example she pointed to last year’s
blackouts in Krasnodar during a heat wave.
Ms. Gimadi also talked about similar problems in winter. “Today the melting of ice on power transmission lines is already regulated by the state at least as far as the most important parameters are concerned. The rules for the design of power installations (the Ministry for Energy’s order passed in 2003) contain such recommendations. The issue is also addressed in the technical policy of Russian Grids,” Ms. Gimadi said. - “They explicitly prescribe the use of automated early ice detection systems, ice melting units and other measures.”
