NEW DELHI - Frequent and long power cuts and water shortage, combined with the escalating mercury levels, left the capital’s residents praying for respite Thursday while Delhi Chief Minister Sheila Dikshit warned of tough times ahead.

While the temperature rose to a merciless 42.2 degrees Celsius Thursday, many parts of the city reeled in darkness thanks to long and frequent power cuts.

Seeing the heat wave conditions, the Delhi government Thursday extended the summer vacations of schools by one week.

“A heat wave condition prevails in Delhi and we have decided to extend the summer vacation for a week. We have issued orders to government and private schools to now open on July 8,” Delhi government’s Education Minister Arvinder Singh Lovely told reporters.

The decision will provide relief to nearly 2 million school-going children in the city.

According to a Delhi Transco Limited official, the city Thursday faced a gap of 378 MW of power between availability and demand due to prolonged heat wave and above normal day-time maximum temperature.

The maximum demand for power rose to 3,967 MW.

“Some of the power stations in the northern region have been having electricity problems, thus leading to the power shortage here,” the official said.

Rajesh Gulati, a hassled bridegroom, and his family sat huffing and puffing without water and electricity on the wedding day in west Delhi Thursday.

“Yesterday, there was no water and even today the situation is the same. On top of that there is no power too. Who would feel like celebrating, especially in this heat? My in-laws, worried about the situation, have gifted me a generator!” Gulati said.

Agitated people protested in various parts of the capital and even vandalised public property.

Chief Minister Dikshit has called for an all-party meeting on power situation Monday and water shortage Tuesday.

The Bharatiya Janata Party (BJP) members for the second consecutive day Thursday walked out of the state assembly, protesting water and power shortage. The assembly budget session is being held at present.

“The situation is very grim and we are not able to meet demand. Nothing is hidden from you,” Dikshit told the assembly.

She, however, warned Delhiites of possible water and power shortage in coming days following delay in monsoon.

“We are asking people to conserve water and power. I am warning everybody of tough days ahead if it doesn’t rain in coming days,” Dikshit told reporters.
