Applicability:
Regulation Applicable on all Wind and Solar Energy Generators (excluding Rooftop PV Solar power projects) in Tamil Nadu
Deviation Accounting: ?The deviation accounting will be carried out based on the Available Capacity:- ???????????????????????????????????????????????????????????????????????????
Generation = ?Absolute Error in % = 100 X Actual Generation – ?Scheduled/ Available Capacity (AvC)
Point of Forecasting: Plants connected to the Intra-State Transmission System or Distribution System, including those connected through Pooling sub-stations, and using the power generated for self-consumption or sale within or outside the State.
Aggregation: Unlike in Karnataka and AP, Tamil Nadu’s regulation does not have a provision to provide an aggregated forecast.
Role of a QCA:
Revisions:
Other Key Points:
Important differences between intrastate and interstate transactions:
Deviation Charges in case of under or over-injection for sale/supply of power within the State
Deviation Charges in case of under or over-injection for sale/supply of power outside the State
The TNERC Regulation for Forecasting & Scheduling, 2019 has not provided a summary of timelines designating the activities to QCA and SLDC, to be accomplished within the following stipulated duration.
Utility category: where the objective is sales of solar energy to a distribution licensee or a third party or self-consumption at a remote location (wheeling). For these systems, the grid connection is through a dedicated gross metering interface.
Consumer category systems: where the objective is self-consumption of solar energy and export of surplus energy to the grid. For these systems, the grid connection is through a consumer service connection of a distribution licensee.
Types of solar plant models:
Incentives:
Grid connectivity and Energy evacuation:
TEDA and TANGEDCO will be the leading government agencies in implementing the new solar policy in the state of Tamil Nadu.
]]>The commission after considering all the comments & suggestions have revised the electricity tariff by 15% for all the category of consumers for FY 2014-15 effective from 12/12/2014.
?The new tariff applicable to industrial and commercial consumers for HT connections can be seen in the table below:
Group captive arrangement will still remain most viable option for the industrial & commercial consumers looking at the hike in the tariff and R&C measures still in place.
Similarly for LT consumers for all categories there has been tariff hike of 15% as can be seen in the order.

]]>The Variable cost component proposed for FY 2014-15 is Rs.3.61 per unit and for the FY 2015-16 is Rs. 3.79 per unit, the control period is 2 years with the tariff period of 20 years.
The commission has proposed to continue the existing wheeling, transmission & scheduling and system operation charges of 50%, as applicable to the conventional power. The cross subsidy charges for the third party open access consumers as proposed to be 50%. While for the generators who are availing Renewable Energy Certificate (REC), normal transmission charges, wheeling charges and line losses has been proposed. The existing CSS of 50% is proposed to continue for this control period.

3. Bagasse Power Projects – The proposed fixed cost component is highlighted in the table below:
The Variable cost component proposed for the FY 2014-15 is Rs.2.93/- per unit and for FY 2015-16 is Rs. 3.07/- per unit, the control period has been proposed 2 years with the tariff period of 20 years.

]]>The details of the tariff determined are given below:
Open Access charges – The commission as promotional measure has decided to adopt 30% of respective charges, in each of the transmission, wheeling, scheduling and system operation charges to solar power. While for the plants availing REC’s, 100% relevant charges will be applicable. Apart from this the Reactive Energy charges and 30% of parallel operation charges will be applicable.
Cross Subsidy Surcharge – 50 % of the cross subsidy surcharge will be applicable for solar power, same is applicable for other renewable power.
The Tariff determined by TNERC is lower compared to the tariff determined by CERC, as the commission has offered a waiver in the CSS and wheeling charges in order to compensate the difference with the added operational incentives.
Tamil Nadu released its Solar Policy in 2012 with a target of 3GW of solar power by 2015, while the state had an installed capacity of 109.26 MW on 31st July 2014. The new tariffs along with waiver in Open Access charges, will result in more investments in the coming year. In addition to this, if SPO is implemented in the state, it will be a major shot in the arm for Solar power in TN, without which the target seems like a distant reality.

]]>Background – The Govt. of Tamil Nadu drafted its solar policy (announced in 2012), mandating certain consumer to buy solar power, which was finalized by the Tamil Nadu Electricity Regulatory Commission (TNERC) in its order dated 7th March 2013. The order stated that – “As prescribed in the Solar Policy, 6% SPO starting with 3% SPO till December 2013 and 6% from January 2014 is applicable”.
The Tamil Nadu Spinning Mills Association appealed to APTEL for the removal of the Solar Purchase Obligation as RPO does mandate purchase of solar power.
The APTEL in its judgment said that the state commission cannot impose any other obligation such as SPO, as RPO already exists in the state. So the State Govt. has moved to the Supreme Court challenging this , as it clearly intends to impose SPO under its Solar Policy.
It is also worth noting that TNERC has mandated RE purchase to a total of 9% under its RPO regulation, which is one of the highest in India, with 0.05% Solar RPO and 8.95% Non-Solar RPO. The commission in its draft RPO Regulation 2014, has increased the solar RPO to 2% and total to 11%, to bolster Solar Power in the state in case SPO is not implemented.
