Wind Energy an Introduction• Fastest Growing Energy in the World

• wind power has the potential to produce 72 Terawatts,5 times more energy than the world consumes*.

• 250 MW of Wind Energy can displace 1.3 billion pounds of greenhouse gases equal to emissions of 175,000 cars or 100,000 sport utility vehicles. Also eliminate 5.9 million pounds of acid rain emissions (sulfur dioxide), 2.8 million pounds of smog emissions (nitrogen dioxide) and about 44 pounds of mercury.

• Wind is part of the answer to the mounting coal shortages and raging environmental pollution in India

Specific Issues in Open Access

• Access Charges are often detrimental.

• Banking facility is not provided.

• Compliances mandated are not sensitive to Wind

Energy charges

For the first 1 Lakh units 360 paise per unit

For the balance units- 410 paise per unit

Banking facility

• Banking facility which existed for last two decades is being denied now in the name of Open Access.

• Wind is not a Real-time dispatchable energy type.

• Wind Availability is from May – September.

• 80-85% Wind Energy produced during this period.

• In order to match consumer demand-uniform across year – Banking is a must.

Wind Sensitive Needs • STOA mechanism cannot be applied.

• UI charged in ABT regime is highly determinant since– Normative PLF or Availability cannot be forecasted – Deviations from the Schedule cannot be controlled – Merit order cannot be applied

• Wind Energy needs to tapped when available

• Levy of Surcharge is highly detrimental

Request

• Favourable Wheeling @ 4% Banking Charges @ 2% for a long period say 10 years.

• Charges be uniform with entire State as one zone.

• Annual Banking facility be provided.

• Exemption from ABT/Scheduling/Merit Order/Surcharge levy

• Must Run Status be conferred

Tariff & Parameters as provided by KERC as

per NCE Tariff Order dated 18.01.2005

• Project Cost- Rs.425Lakhs/MW • PLF – 26.5% • O&M expenses - 1.25% of the project cost with annual

escalation of 5%. • interest on working capital - 12.5% on two months bills.• Auxiliary Consumption – 0.5% • Tariff per unit – Rs.3.40/- freezed for 20 years

Capacity Breakup of Wind Installations

• Tamil Nadu –2036 MW • Karnataka – 410.7 MW • Andhra - 120.6 MW • Gujarat – 253.5• Rajasthan- 284.8• Maharashtra – 456.3 MW • M.P.- 28.9 MW • Kerala –2 MW • W.Bengal – 1.1. MW
