Perform, Achieve & Trade

Intro­duc­tion
The National Action Plan on Cli­mate Change was released by Hon­or­able Prime Min­is­ter of India in June 2008 The Action Plan Out­lines 8 Mis­sions ; Each Mis­sion has out­lined spe­cific goals

  • Missions under NAPCC
  • National Solar Mission
  • National Mis­sion for Enhanced Energy Effi­ciency (NMEEE)
  • National Mis­sion on Sus­tain­able Habitat
  • National Water Mission
  • National Mis­sion for Sus­tain­ing the Himalayan Ecosystem
  • National Mis­sion for a Green India
  • National Mis­sion for Sus­tain­able Agriculture
  • National Mis­sion for Strate­gic Knowl­edge for Cli­mate Change

  • NMEEE Mission Goals
  • The overall national energy consumption reduction target under PAT II given to 621 units is 8.869 MTOE covering 11 sectors.
  • 2nd Cycle from 2016-17 to 2018-19 (3 year's cycle)


One of the New Initiatives under NMEEE (Relevant to Thermal Power Stations):

Perform, Achieve, Trade

The mar­ket based mech­a­nism to enhance the cost effec­tive­ness in improv­ing the Energy Effi­ciency in Energy Inten­sive indus­tries through cer­ti­fi­ca­tion of energy sav­ing which can be traded

The PAT Scheme under Energy Conservation Rules, 2012
(PAT Rules)
BASIC FRAMEWORK OF PAT SCHEME

  • Mechanism
  • Target Setting & Compliance Period by Admin­is­tra­tor (CEA & BEE)
  • Monitor, Verification & Certification by Des­ig­nated Energy Audi­tors (DENA) (Accred­ited by BEE)
  • Underachievers – Penalized by buying ESCerts (Energy Savings Cer­tifi­cate), Over­achiev­ers – Issuance of ESCerts for bank­ing or trad­ing for later use.
  • Activity Flow
  • Infor­ma­tion through Base­line Audit (Aver­age of Three Years data)
  • Tar­get Set­ting (Dec­la­ra­tion of Base Year, Tar­get Year)
  • Com­mu­ni­ca­tion to Des­ig­nated Con­sumer ( All Power Sta­tions of WBPDCL).
  • Prepa­ra­tion of Per­for­mance Assess­ment Doc­u­ment (PAD or Form A) & Com­mu­ni­ca­tion to BEE/​SDA (State Des­ig­nated Agency)
  • Ver­i­fi­ca­tion of PAD through DENA (Form B)
  • Ver­i­fi­ca­tion check by DENA and sub­mis­sion of com­pli­ance doc­u­ment (FORM D)
  • Specific Energy Consumption(SEC)

  • SEC = E/P
    Where E = Input Energy Amount (eg Coal in kg for Ther­mal Power Plants), P = Out­put Prod­uct (Elec­tric­ity in Kwh for Ther­mal Power Plants)

  • Estimation of Energy saving (MTOE= Metric Ton of Oil Equivalent)

  • = Pbase X (SECbase - SECtar­get)

    Pbase = Base­line Pro­duc­tion: Aver­age of 2007 – 8, 2008 – 9 & 2009-​10
    SECbase = Aver­age of 2007 – 8, 2008 – 9 & 2009-​10
    SECtarget = SEC as esti­mated in 2014 – 15

  • 1 MTOE = 1 ESCert
  • 1st Cycle from 2012 – 13 to 2014 – 15 (3 years cycle)
  • After three years a com­plete mea­sure­ment will be under­taken for ver­i­fy­ing SEC and plant capac­ity for each Des­ig­nated Con­sumers by DENA.

  • Correction/​Normalization Fac­tors – Fac­tors which affect SEC

    • Input Pri­mary Energy (Fuel Link­age & Qual­ity of Fuel) (As fired Basis Coal)
    • Capac­ity Uti­liza­tion (Back­down, Non-​availability of Fuel)
    • Envi­ron­men­tal Stan­dards & Nat­ural Disaster

  • For every devi­a­tion from tar­get authen­tic doc­u­men­ta­tion should be pre­sented to BEE/​Energy Audi­tors for incor­po­ra­tion of correction/​normalization factors.
  • Esti­mated National Tar­get (Energy Sav­ings) = 6.6MTOE at the end of 1st PAT Cycle (2014−15).
  • Stakeholders
  • Admin­is­tra­tor : MoP/​Central Govt (CERC in the case of Ther­mal Power Stn.)
  • Nodal Agency : Bureau of Energy Efficiency
  • Imple­menter : Des­ig­nated Con­sumers like KTPS, BTPS, BkTPP, SgTPP and STPS
  • State Admin­is­tra­tor : State Des­ig­nated Agency like WBSETCL
  • Ver­i­fier : Accred­ited Energy Audi­tor ( to be Des­ig­nated by MoP)
  • Role of Cen­tral Govt.
  • As per noti­fi­ca­tion dated the 30th. March, 2012, issued by Min­istry of Power, Govt. of India, New Delhi on ‘Per­form Achieve and Trade (PAT)’,issued under EC Act 2001, Tar­get Spe­cific Energy Con­sump­tion i.e. Net Heat Rate (Kcal/​Kwhr) of five Ther­mal Power Sta­tions of WBPDCL have been noti­fied which have to be achieved by 2014 – 15.

MIN­ISTRY of POWER, New Delhi, Vide NOTI­FI­CA­TION Dated the 30 th March, 2012. [pub­lished in Part-​II Section-​3, Sub-​Section (ii) of Gazette of India, Extra­or­di­nary], in con­sul­ta­tion with the Bureau of Energy Effi­ciency, spec­i­fied for the des­ig­nated con­sumers the energy con­sump­tion norms and stan­dards for the period from 2012 – 13 to 2014 – 15 in rela­tion to their cur­rent level of energy con­sump­tion, being the base­line energy con­sump­tion norms and stan­dards which need to be com­plied within the tar­get year 2014 – 15.
