EXTRACTS FROM ELECTRICITY ACT 2003

Para 3(1) NATIONAL ELECTRICITY POLICY AND PLAN:

The Central Government shall, from time to time, prepare

the national electricity policy and tariff policy, in consultation

with the State Governments and the Authority for

development of the power system based on optimal

utilisation of resources such as coal, natural gas, nuclear

substances or materials, hydro and renewable sources of

energy.

Para 6.3 Harnessing Captive Generation

• Captive generation is an important means to making competitive power available. Appropriate Commission should create an enabling environment that encourages captive power plants to be connected to the grid.

• Such captive plants could inject surplus power into the grid subject to the same regulation as applicable to generating companies.

• The prices should be differentiated for peak and off-peak supply and the tariff should include variable cost of generation at actual levels and reasonable compensation for capacity charges.

• Alternatively, a frequency based real time mechanism can be used and the captive generators can be allowed to inject into the grid under the ABT mechanism.

Para 6.4 : Non-conventional sources of energy generation

Pursuant to provisions of Section 86(1)(e) of the Act, the Appropriate Commission shall fix a minimum percentage for purchase of energy from such sources taking in to account availability of such resources in the region and its impact on retail tariffs.

Para 6.4 contd…

It will take some time before non-conventional technologies can compete with conventional sources in terms of cost of electricity. Therefore, procurement by distribution companies shall be done at preferential tariffs determined by the appropriate commission.

POSSIBLE OPTIONS FOR SALE OF ENERGY:

- Short Term Open Access

- Unscheduled Interchange(UI)

- Through Tariff determined by Regulator

ISSUES OF IMPORTANCE IN CASE OF NON-CONVENTIONAL (Renewable) ENERGY SOURCES

- FAVOURED ACCESS / WHEELING CHARGES

- POSSIBILITY OF BANKING

- EXEMPTION FROM MERIT ORDER

- MUST RUN STATUS

- ENABLING TARIFF BY STATE COMMISSIONS

POSSIBLY SIMILAR TREATMENT IS TO BE MOOTED TO SUCH OTHER RENEWABLE SOURCES VIZ. MINI / MICRO HYDEL ETC.

SALE OF NON CONVENTIONAL ENERGY THROUGH STOA:

- CAN NOT BE DISPATCHED/ REGULATED ON A REAL TIME BASIS;

- AVAILABLE ON SEASONAL BASIS;

- TO BE TAPPED WHENEVER AVAILABLE

- APPLICATION OF ACCESS CHARGES (Access Charges could very from 10 -25 %)

HENCE POSSIBILITY OF SELLING N.C. ENERGY THROUGH STOA IS NOT VERY ENCOURAGING.

SALE OF WIND ENERGY THROUGH UI

- CANNOT REGULATE THE GENERATION DEPENDING ON FREQUENCY

AVG. UI RATE COMES IN THE RANGE OF AROUND Rs. 2.00 – 3.00 Per unit

HENCE POSSIBILITY OF SELLING THROUGH UI MAY NOT BE ENCOURAGING ALL THE TIME
