He alleged irregularities pertaining to purchase of materials, allotment of major project works at higher rates to favour some firms, companies and contractors.
Dalal also questioned BJP government's decision to appoint Shatrujeet Kapoor, an IPS officer, as chairman-cum-managing director of Uttar Haryana Bijli Vitran Nigam and chairman of Dakshin Haryana Bijli Vitran Nigam, the state's power utilities.
He told reporters that the "irregularities" in the Power department had been pointed out earlier in the report of the Comptroller and Auditor General (CAG).
Dalal cited examples of alleged overpayment made to the contractors and revenue loss due to supply of power under categories not conforming to the tariff order.
"There was an extra expenditure of Rs 2,483 crore incurred due to procurement of coal through costly sources," he claimed.
Dalal said in his memorandum to the Governor, he has requested him to take cognizance of the "large-scale irregularities/scam" in the Haryana Power department/ DISCOMS.
