276 The electricity surcharge ADJUSTMENT of domestic tariffs for electricity has been introduced at the request of the Government. To curtail use of current during the peak periods, roughly one-third of a penny will be added to the normal running charge per unit during three winter months; but the normal charge will be reduced by one-tenth of a penny per unit during the remaining nine months of the year. Domestic consumers must use less electricity— between 8 a.m. and 10 a.m. —up to noon when the weather is very cold .
