As per the tariff order of DERC for the year 2014-15, the variable tariffs for the commercial and industrial categories for the year 2014-15 are in excess of Rs 9.00 per kWh. A revenue deficit surcharge is imposed on the fixed and variable charges as per the orders of DERC and the Supreme Court ruling.

The table below shows the break-up of tariffs for domestic, commercial and industrial categories.

The fuel adjustment surcharge or power purchase cost adjustment charges (PPAC) has been set at zero for the time being in Delhi as shown above. However DERC has already passed an order on 13^th Nov 2014 to increase the PPAC to 2.5% for TDPPL, 4.5% for BRPL and 7.0% for BYPL. However, the order was suspended due to reasons related to lack of complete information on fuel cost from various generators. Once implemented, the PPAC would be charged on fixed and variable charges both which would lead to an increase of tariff from 20 paise to 70 paise per kWH all consumer categories.

The tariff for the domestic consumer categories at various levels of consumption are as follows.

The tariff for the domestic category remains low however as all the consumers get the benefit of telescopic tariffs in the state.

Delhi Discoms have already filed the petition for increasing the tariff for the year 2015-16 which is currently being reviewed by DERC.

Given such a high variable tariff, the roof top solar solution provides a very attractive proposition to save the energy cost from immediate effect.
