The Shanghai Municipal Electric Power Company is urging Shanghai’s shopping malls to close down when temperatures exceed 37 degrees Celsius this summer in an attempt to save power for use by residents. Power shortages in Shanghai could exceed 1 gigawatt, and this is the latest plan to keep outages under control. The power rationing plan was approved for 3,000 non-industrial users, although it remains “advisory and not compulsory.” Unsurprisingly, some malls have already protested the closures and say they will not comply. Residents of the city are encouraged to set air conditioners no lower than 26 degrees Celsius (or in other words, yucky but livable) and large office buildings will be asked to shut off the AC for one hour on days where temperatures surpass 35 degrees. So far this plan sounds like a list of reasonable but toothless suggestions that will probably result in little or no actual compliance.
