Kerala mulls promotional tariff for solar producers
Kerala State Electricity Regulatory Commission has stated that renewable obligation for licensees of power distribution in Kerala for 2012-13 will be about four per cent of consumption. At least 0.25 per cent of this will be sourced from solar.
The Commission proposes to bring out promotional tariff for the solar PV plants of varying scale in the State. As a first step, promotional tariff for solar projects supplying to the grid is considered. The Commission observed that even though many thin film technologies offer 25 year performance warranties, there is no long-term performance data available.
There is a need within the market to develop confidence on the long-term performance in the harsh Indian weather conditions. Solar power projects primarily depend upon efficiency of the photovoltaic technology and type of (solar) tracking system used.
Land requirement increases for photovoltaic projects utilising either lower efficiency technologies or solar tracking. It is acknowledged that tracking technologies would require more area, but the cost of land is compensated through the increase in the plant’s energy yield.
