ISLAMABAD - Ministry of Water and Power on Thursday unveiled energy conservation measures for upcoming six months to help lessen impact of the growing energy crisis on countrys economy. Under the energy conservation measures, government installations including the offices of president, the prime minister, provincial chief ministers, federal cabinet and other public offices will curtail their electricity consumption by 50 per cent. Federal Minister for Water and Power Naveed Qamar in his detailed briefing to the National Assembly on Thursday said no official below BPS 20 can use air-conditioner. The authorised official too can use it after 11:00 am. The ministry has recommended five working days, with two weekly offs, in all government and allied offices, he added. Under the measures, he maintained, use of all street lights would also be reduced, power supply to billboards, commercial decorative lighting will be cut off. He, however, added that this measure would remain in place for six months and would be reviewed accordingly keeping in view the circumstances. He said the ministry has also recommended closure of markets by 8:00 pm. He said the measures would save about 1,000 to 1,100 megawatt electricity. New digital electricity meters would be installed, he said adding, govt was trying to check power theft and strict action would be taken against perpetrators. He said the government would also seek other means of power generation and work on five big energy projects was also underway. He said the govt would ensure uninterrupted power supply to industrial sector to avoid negative impacts of the energy crisis on economic development. The industrialists would be asked to import digital machinery which consumes cheap electricity, he said. Sources in the Ministry of Water and Power told INP that the plan had to be put in place in the next few days as the shortfall in demand and supply had crossed 3,000 MW and in the coming months it could further go up with people switching on their air conditioners. The plan was expected to be discussed at the cabinet meeting but the prime minister has desired it should be approved by the Council of Common Interests. Sources said industries would also be required to rotate their weekly off days to conserve electricity to the maximum. However, there was no decision yet on advancing of clocks by one hour.
