Most of the small and medium enterprises (SMEs) in Haryana have not been able to function optimally due to power shortage. SMEs face almost six to eight hours of power failure everyday. SMEs with strong financials rely on captive power, run on diesel gensets, that costs about Rs 12.50 per unit. Power supplied by the the state electricity board costs Rs 4.50 per unit. The going is tough for those who cannot afford captive power. IS Paul, managing director of Panchkula based Drish Shoes Ltd says: "It is not only the issue of availability of power , but of quality as well."
