Protesting employees raised slogans against the state government at various places for its decision of privatising the job of maintenance and operation of 23 sub-divisions.
Describing the decision of the employees to go on strike as unjustified, the government said power supply in "the whole state was normal".
The decision to proceed with the strike came after talks with state government remained inconclusive on Monday.
The government was adamant on its decision of "privatisation", he said, alleging it had forced them to go on strike.
Around 23,000 employees of electricity department in the state have stopped work, he said.
"The matter can be resolved still if Chief Minister Manohar Lal Khattar himself intervenes in the matter and the government rolls back the decision of privatisation of 23 sub divisions," Lamba said.
He added the strike shall be peaceful and no power employee shall indulge in any attempt to disrupt power supply.
Haryana government had already invoked ESMA to prevent disruption in power supply due to strike.
Meanwhile, Haryana Chief Secretary D S Dhesi said despite the strike by a "section of employees" of the power utilities, the consumers were getting 8,000 MW of power today by noon as compared to the average supply of 7,200 MW in the last one week at the same time.
The Chief Secretary, who was accompanied by Additional Chief Secretary, Power, Rajan Gupta, told reporters here "the power supply in the whole state was normal. About 36 per cent of total employees remained absent. The supply, however, was maintained by the officers with the help of remaining employees. All the officers of the department are on duty round the clock. Special emergency teams are working to attend to the complaints promptly."
Those found trying to disrupt the supply of power would invite stern action against themselves, he warned.
Dhesi said the government was committed to ensure
uninterrupted supply of power to all categories of consumers in urban as well as rural areas and it was also taking steps to ensure that the people are not put to any inconvenience.
He said that the government would not take any step which would adversely affect the employees.
He added that the government was of the view that the present strike by power employees was "unjustified" and uncalled for.
Gupta said a reference has been made to the Labour Tribunal for conciliation of the dispute. All other legal measures have been taken to ensure discipline.
"In case an employee indulges deliberately in sabotage of power supply, strict action as per law will be taken against such person," he said.
Gupta said the agitation being resorted to by a section of the employees is totally unjustified.
The employees are agitating against the policy decision of the state government of engaging service providers in 23 sub-divisions for undertaking maintenance works and redressing complaints of the consumers relating to interruption of power supply.
"This is a win-win situation for both the government and the employees as the consumers shall get good service at low cost," he said and hoped the employees of the utilities would cooperate to continue it.
The service providers have been asked to arrange sufficient manpower and equipment so that the complaints of breakdowns received from consumers are addressed in a time bound manner.
They have also been asked to carry out preventive maintenance to avoid breakdown in supply of electricity.
He stated that a requisition has been sent to the Haryana Staff Selection Commission for filling up of 5000 posts for managing sub-stations of the Power Utilities efficiently.
In the last two years more than 200 sub-stations have been augmented or commissioned. An investment of nearly Rs 10,000 crores has been planned in the next three years, he said.
