Cement Energy and Environment

Energy Services concept has come rrom North America where the companies providing such concept arc known as ESCOs. ESCOs give Performance Guarantees to the client lor th e Energy Conservation Measures (ECM) recommended by them. by signing a Performance Contract, rinanci ng the ECM. and proviuing EPC & Turnkey services for the same. The ESCO n.:ccives its service charges only from the savings achieved by implementing the measures. DESCL is in the process of signing an agreement with a US Canadian ESCO consortium lor providing this service. The DSCL Esco System is designed to address the generic prohlems faced by Indi an inuustries incl udi ng lack of credit. inability or linancing in vestments in energy efficiency, project ri sks and performance risks. DSCL Esco System will initially provide the services to the industries anu utilities, and later diversify into hotel, hospital s and building sectors. The services offered would cover a wide range of technology menu covering: HVAC Co-generation Demand Side Management Waste heat Captive Power factor recovery generation improvement Process synthesis Utility Energy efficient management lighti ng Process Renewable Computerised integration measurement & control system NATIONAL AWARDS FOR ENERGY EFFICIENCY IN INDIAN CEMENT INDUSTRY The Scheruc 'The National Awards for Energy Erticicncy in Indi an Cement Industry was started by NCB in I 9H6 and the Awards arc being given ever since. The objecti ve of the scheme is to motivate competiti ve improvement in energy perrormance and to improve energy consciousness in Indian cement industry by according national recognition to the crrorts for realisation or progressively lower energy consumption levels. Excellence in energy efliciency. judged from the Improvement in energy performance over preceding years, has hccn achieved by a numhcr or cement plants tn the country through rhe fo ll owing broad e!Torts: •• II Selling up of in -house Energy Audit & Monitoring Cells Operational control and optimisation Fixing of be1tcr energy standards/targets Upgrudation of process comrol and instrumentation facilities iii • Rctrolitting and adoption of energy ellicient equipment/system • Active participati on of employees and human resource development through training The progressively declining trend in energy consumption - both thermal and electrical - for dry process plants from 1994-95 to 1997-98 is depicted in Figures I and 2. 810 ~-----------------------------------. 804.79 800 794.73 ~ 790 u 783.63 "' .>: 'iii 780 772. 4 u X: 770 760 +-----------~----------~----------~ 94-95 95-96 96-97 97-98 Figure 1 Thermal energy consumption trend in dry process 10
