Power Grid Corporation of India Limited (POWERGRID, the 'Central Transmission Utility (CTU)' of the country and a 'Navratna' Company operating under Ministry of Power, is engaged in power transmission business with the responsibility for planning, implementation, operation and maintenance of Inter-State Transmission System (ISTS). POWERGRID is a listed Company, with 57.90% holding of Government of India and balance by Institutional Investors & public.
POWERGRID, as on 30th September 2017, owns & operates around 1,42,989 ckm of Extra High Voltage (EHV) transmission lines spread over the length and breadth of the country and 226 EHV AC & HVDC Sub-stations with transformation capacity of more than 3,09,684 MVA. Its vast transmission network wheels more than 45% of the power in the country. The availability of this huge transmission network is consistently maintained over 99% through deployment of state-of-the-art operation & maintenance techniques at par with global standards.
During FY 2016-17, POWERGRID has achieved a turnover of about Rs. 26,581.46 Crore and Net Profit of Rs.7,520.15 Crore. As on 31.03.2017 Gross Fixed Assets of the company have also grown to Rs.1,49,730 Crore.
High Capacity Power Transmission Corridors (HCPTCs) have been implemented to meet bulk power evacuation requirement of various Independent Power Producers (IPPs) mainly coming up in resource rich and coastal areas such as Chhattisgarh, Odisha, Madhya Pradesh, Sikkim, Jharkhand, Tamil Nadu and Andhra Pradesh. Implementation of these corridors has been taken up in a phased manner matching with generation projects.
The total inter-regional transmission capacity (220kV and above) of country has been enhanced from 27,150 MW to 75,050 MW from XIth to XIIth plan. This endeavour of POWERGRID under the guidance of Ministry of Power has enabled in moderation of the prices of electricity in Northern Region and ensured reliable supply of electricity.
POWERGRID has achieved a capital investment of about Rs.1,12,600 crore for development of inter-State transmission system during XII Plan against a target of Rs.1,10,000 Crore. During the XII plan it has added about 45,900 ckm of transmission line and about 1,64,000 MVA of transformation capacity against a target of 40,000 ckm and 1,00,000 MVA respectively.
The Company has an excellent credit rating with financial institutions, thereby, is placed in a comfortable position in terms of resource mobilization. POWERGRID is also playing a major role in facilitating grid interconnection of renewable generation across the country through implementation of portion of ISTS part of Green Energy Corridors.
Conserving Right-of-Way (RoW), minimizing impact on natural resources, coordinated development of cost effective transmission corridor, flexibility in upgradation of transfer capacity of lines matching with power transfer requirement are major areas of concern in development of transmission network in the country. In this direction, the Company has been working on higher transmission voltages of ±800 kV HVDC & 1200 kV UHVAC. The ±800 kV, 3000 MW HVDC Bi-pole line (CK-I) connecting Champa in Chhattisgarh to Kurukshetra in Haryana has been commissioned recently. This transmission system is further being upgraded to 6000 MW capacity with addition of 2nd HVDC Bipole (CK-2) of 3000MW, ±800kV HVDC Terminals which is expected to be completed by December 2018. Similarly, power flow through 1200 kV National Test Station (NTS) has commenced at Bina, Madhya Pradesh.
To shore up its revenue and create value for its stakeholders, POWERGRID diversified into telecom business, leveraging its country wide transmission infrastructure. Company is providing back-bone connectivity to all metros, major cities & towns including remote areas of J&K and North-Eastern States etc. Total network coverage is more than 41,988 kms and numbers of Points of Presence (PoPs) locations are more than 662. Having Intra city network in 105 cities across India, the Telecom Backbone Availability for the year 2016-17 was about 99.9%.
POWERGRID has successfully completed the prestigious NKN (National Knowledge Network) project devised by Govt. of India, which connects all knowledge centres across the Country such as Indian Institutes of Technology (IITs), Indian Institute of Sciences (IISCs) etc., on a high speed connectivity Company has signed an agreement with Bharat Sanchar Nigam Limited (BSNL) to improve the telecommunication connectivity with the North-Eastern States including Sikkim. It envisages the provisioning of bandwidth on optical fibre media laid over existing high tension electric transmission network. After completion of the proposed connectivity, the reliability of the telecom services improves substantially in North-Eastern region including Sikkim.
As a part of Government of India plan to connect 250,000 Gram Panchayats (GP) in the Country, POWERGRID one of the implementing agencies for BharatNet project and has been entrusted with the task of development and maintenance of the National Optical Fibre Network in states, namely Andhra Pradesh, Telangana, Himachal Pradesh, Jharkhand and Odisha.
Further, POWERGRID is playing a significant role in carrying forward the distribution reforms through undertaking Deendayal Upadhyaya Gram Jyoti Yojana (DDUGJY) and Integrated Power Development Scheme (IPDS) works on behalf of the Govt. of India in the country.
POWERGRID has emerged as a strong player in South Asia and is playing an active role in formation of a strong SAARC grid for effective utilization of resources for mutual benefits. Presently, various electrical interconnections exist between India & Bhutan, India & Nepal and India & Bangladesh. Further, the interconnection between India & Bhutan, India & Nepal and India & Bangladesh are being strengthened for substantial exchange of power across the borders.
POWERGRID is offering consultancy services to various National clients & International clients, including many South Asian, African, and Middle East countries.
POWERGRID is implementing the prestigious and State of the Art, Renewable Energy Management Centres (REMC) for managing the renewable generation integration and operation which shall include a host of activities from renewable energy forecasting to energy balancing and generation scheduling. In Smart transmission, POWERGRID has been implementing Synchrophasor Technology in its Wide Area Measurement System (WAMS) Project through installation of PMUs (Phasor Measurement Units) at different locations in all regions across the country, which facilitates better visualization and situational awareness of the grid events such as grid robustness, oscillations, angle/ voltage instability, system margin etc. as well as decision support tools. POWERGRID also acts as 'nodal point' in prestigious "India Smart Grid Task Force" Secretariat for Government's activities related to Smart Grid.
