15. The Board may, after an investigation, which may be only summary, change the prices demanded by any distributor for the sale of electricity, in such manner as to make them conform to the requirements of this act.
The prices so fixed by the Board shall be compulsory upon the distributor who shall not discontinue the service upon the consumer’s refusal to pay a higher sum than the rates so determined, under penalty of damages. Any sum paid beyond the rate fixed by the Board may be reclaimed notwithstanding any agreement or stipulation to the contrary.
