Wind potential
Wind Potential

Resource Assessment

  • Existing estimate of 49 GW is obsolete- TN already harnessed 5.5 GW- another 9 GW in pipeline.

  • Existing assumptions for potential Estimation

    • Sites having wind potential of 200w/sq m at 50 meter hub height considered economically feasible

    • Availability of land in potential sites @ 2 % of the entire area

    • Wind Farm requirement @9 MW/sq km

      May Require Revision

  • Alternative estimates suggest much higher potential- 400 GW- 1200 GW.

  • Lawrence Berkeley National Laboratory, USA- even without farm land potential is around 1000 GW

  • Group’s Suggestion: Urgent need to carry out comprehensive potential - Action Initiated


  • Wind resource assessment at 100m level
    Wind Resource Assessment at 100m level

    • Realistic Assessment of wind potential at 100m anemometry based on actual availability of land - in seven wind potential states (Tamil Nadu, Karnataka, Andhra Pradesh, Maharashtra, Gujarat, Rajasthan, Madhya Pradesh).

    • Funding support for resource assessment exercise to be provided by G.O.I

    • Project already initiated by C-WET in association with SNAs.

    • The exercise to be completed in three years


    Wind power density condition
    Wind Power Density Condition

    From 1st August 2011, the condition of no installation below 200 Watt/sqm, has been removed

    Rational

    • New Generation Machines capable of harnessing lower wind areas

    • lower wind density regimes can have higher CUF

    • All stakeholders, investors, banks etc. understand risks

    • Such conditions does not exists anywhere in world


    Wind forecasting and schedules
    Wind Forecasting and Schedules

    • IEGC (May, 2010) – ‘Wind generators shall be responsible for forecasting their generation upto an accuracy of 70%. If the actual generation is beyond +/- 30% of the schedule wind generator would have to bear the UI charges’.

    • Industry is not ready with Forecasting –delayed by 1 year- now to start 1 Jan 2012

      Task in Hand

    • Forecasting is necessary to transform wind from infirm to semi-firm power – a condition necessary to create countrywide market for wind power

    • Industry to take lead- Help develop capacity so that a number of forecasting players emerge


    Re powering
    Re-powering

    • About 4000 MW with unit size below 500kw

    • For better potential harnessing – replace old and smaller generators by larger capacity & new generation wind turbines.

    • Issues - Land ownership, land costing and decommissioning cost

      - States reluctant to go for new PPA

      MNRE is working on

    • Realistic assessment of re-powering potential

    • Creation of an appropriate policy framework for re-powering including- Revision of PPA for repowered projects or transmission of power to other states

      States are requested to provide suggestions


    Offshore wind energy global deployment status
    Offshore wind Energy – Global Deployment Status

    • Onshore wind energy have reached to mass deployment globally, the offshore exploitation of wind energy potential is yet to take off

    • Advantage include: more electricity; higher power density compared to land; less obtrusive; can provide cost competitive electricity to coastal region.

    • According to an estimate there is potential of 2800TWh by 2020 and 3500 by 2030 in Europe.

    • Europe is the global leader in terms of offshore wind energy installation.

    • Globally installations have reached - 2500 MW . (Europe : 2,400 MW followed by China - 100MW and Japan 1MW.

    • 100 GW Projects proposed or under development in Europe as of September,2009.

    • EU targets to establish 40 GW by 2020 and 150GW by 2030.


    Offshore Wind Energy – Technology Status

    • The offshore wind farms in the water depth from 0.8 to 220 m. depth with monopile, jacket, tripod and floating technologies.

    • Offshore Turbines are based on the same technology as the onshore and their residual life is also the same. i.e about 20 years.

    • The rated capacity of the Turbines are at 3MW, 3.6MW and 5MW.

    • At different depth the turbine installation requires different type of bases for stability .

    • A monoplile base is used for water up to 30 m depth, where as turbines are installed on tripod or steel jacket base for 20-80 m depth water.



    Offshore wind deployment barriers
    Offshore Wind deployment: Barriers Type Base

    • Higher cost of energy than land based installations

    • Cost on associated infrastructure: vessels for turbine installations, port and harbor upgrades, manufacturing facilities, work forced training programme maintenance

    • Limited experience in deep waters

    • Technical challenges:- infrastructure development to support fabrication, installation, interconnection, operation and maintenance

    • Yet to evolve standardized approval process( so far it has been on case to case basis)
