The issues related to implementation of policy has become a damper for the plans of Tamil Nadu to establish more Solar power generation facilities, say experts. In terms of implementation of roof-top solar, while it is easy to implement, it would require some attractive incentives and policies to be in place to attract more building owners though it would not be difficult to achieve a target of 1000 MW of roof-top facility by 2019 in South India, they said.In the Confederation of Indian Industry (CII) Southern Region is organizing a conference on ‘Roof Top Solar’ with the theme – Driving 1,000 MW by 2019 in Southern Region: Issues & Challenges, S Nagalsamy, retired member of Tamil Nadu Electricity Regulatory Commission (TNERC) said that various issues related to the implementation of the policy, including the fixing of tariff has affected the implementation of solar power facilities in the State.While the cost of production in solar power facilities has come even below than that of the conventional power resources, the tariff has been kept on higher side. The incentives has also been offered to those who set up captive facility. However, various decisions including that of a Solar Purchase Obligation (SPO) has dragged the government to the court and this has affected the implementation. As a result, Tamil Nadu could only achieve 200 MW out of its set target of 3,000 MW in three years, he added.
