(1) To investigate, study, develop and place into effect procedures and to investigate, study, develop, purchase, lease, own, operate, maintain, and put into service devices, which will temporarily curtail or cut off certain types of appliances or equipment for short periods of time whenever an unusual peak demand threatens to overload the electric system or economies would result; and
