    2.0 INTRODUCTION

    2.1 IMPORTANCE OF ENERGY CONSERVATION & ITS BACKGROUND

    Energy is one of the most coveted inputs in the development of any society. With the

    accelerated growth of the economy the demand for energy is increasing exponentially. On the

    supply side the stock of the conventional energy resources like fossil fuel are limited and

    rapidly depleting. India gradually becoming dependent on external sources of energy thereby a

    considerable part of the GDP is exhausted for procurement of energy.

    One of the easier available options for survival is energy conservation through energy

    efficiency improvement; thereby reduction of energy consumption and cost there of through

    strategic energy management concept and mechanism.

    Energy conservation is a worldwide objective. The energy policy of the Government of India

    also calls for conservation of energy. With the enactment of Energy Conservation Act-2001,

    amongst others has emphasized upon the power of the appropriate Govt. to enforce efficient

    use of energy and its conservation.

    The management of OIL has adopted the energy system study and implements solutions

    thereof with the objective to optimal utilization and output of available energy consuming

    systems and to conserve energy.

    In view of energy efficiency improvement and cost reduction program for long-term business

    solution the management of OIL sought the services of PCRA for energy system study on Gas

    Compressors, air compressors and Lighting systems at their plant at Duliajan in Assam.

    PCRA has studied the energy systems of the plants accordingly with the help of OIL

    representatives. During the study, the energy audit team has mapped present status of

    electrical power and energy systems at the plant premises, identified areas of weaknesses,

    major energy loss areas etc. The study has identified potential scope for improvement and

    energy efficiency improvement in major energy consuming systems. It also recommends cost

    effective and fast pay back solutions for energy cost control.

    2.2 COMPANY PROFILE

    The story of Oil India Limited (OIL) traces and symbolizes the development and growth of the

    Indian petroleum industry. From the discovery of crude oil in the far east of India at Digboi,

    Assam in 1889 to its present status as a fully integrated upstream petroleum company, OIL has

    come far, crossing many milestones.

    On February 18, 1959, Oil India Private Limited was incorporated to expand and develop the

    newly discovered oil fields of Naharkatiya and Moran in the Indian North East. In 1961, it

    became a joint venture company between the Indian Government and Burmah Oil Company

    Limited, UK.

    In 1981, OIL became a wholly-owned Government of India enterprise. Today, OIL is a premier

    Indian National Oil Company engaged in the business of exploration, development and

    production of crude oil and natural gas, transportation of crude oil and production of LPG. OIL

    also provides various E&P related services and holds 26% equity in Numaligarh Refinery

    Limited.

    The Authorized share capital of the Company is Rs. 2000 Crores. The Issued, Subscribed and

    Paid share capital of the company is Rs. 601.14 Crores. At present, The Government of India,

    the Promoter of the Company is holding 78.43% of the total Issued & Paid-up Capital of the

    Company. The balance 21.57% of the Equity capital is held by others.

    OIL has over 1 lakh sq km of PEL/ML areas for its exploration and production activities; most of

    it is in the Indian North East, which accounts for its entire crude oil production and majority of

    gas production. Rajasthan is the other producing area of OIL, contributing 10 per cent of its

    total gas production.

    Additionally, OILs exploration activities are spread over onshore areas of KG Basin, Mahanadi

    Basin, Cauvery Basin, Andaman Basin and Gujarat-Kutch Basin etc. OIL also has participating

    interest in NELP exploration blocks in Mahanadi Offshore, Mumbai Deepwater, Krishna

    Godavari Deepwater, etc. as well as various overseas projects in Libya, Gabon, Iran, Yemen,

    Nigeria, Sudan and Venezuela.

    In a recent CRISIL-India Today survey, OIL was adjudged as one of the five best major PSUs and

    one of three best energy sector PSUs in the country.

    Objective of Energy Audit

    With the advent of energy crisis and exponential hikes in the costs of different forms of

    energy, Energy Audit is manifesting its due importance in Industrial Establishments. Energy

    Audit helps to understand more about the ways energy and fuels are used in any

    Establishment and helps in identifying areas where waste may occur and scope for

    improvement exists.

    Energy Audit is the key to a systematic approach for decision-making in the area of energy

    management as it attempts to balance the total energy inputs with its use and serves to

    identify all the energy streams in a facility/ Establishment.

    It was with this objective that Petroleum Conservation Research Association (PCRA) was

    entrusted by OIL, the Energy Audit of Gas Collecting Station#1, Duliajan.
