Foreign market research firm Wiseguyreports.Com recently released Indian electricity market research report said that by 2022, India will increase the power line 105,580 km (wire loop length, the same below), an increase of substation capacity 292,000 MVA, which requires 2.6 trillion investment rupee.
Power transmission system
As of December 2016, the total length of transmission lines in India reached 362,121 km, with a total transformer capacity of 689,984 MVA (excluding high-voltage direct current) and a voltage rating of 220 kV and above.
In FY 2015-16, the length of transmission lines in India increased by 28,114 kilometers, the highest in a single year and the transformer capacity increased by 61,349 MVA.
Meanwhile, as of the end of December 2016, the transmission capacity in India increased from 58,050 MW to 62,550 MW.
From the project perspective, in the 2015-16 fiscal year, the transmission sector in India continued to push forward the construction of high-voltage transmission lines and the key ± 800 kV HVDC transmission project.
These include the bipolar circuit that connects Biswanath Chariyali-Agra and the first HVDC transmission line in India with a length of 3506 km and will be commissioned in September 2015.
In September 2016, a ± 800 kV bipolar line of 2574 km in length was commissioned. In the meantime, India's national grid is also testing the 1,200 kV national test station in the Bina area.
Social Capital can participate in all TBCB projects during January-December 2016.
While Sterlite Power Transmission India has the largest number of TBCB projects in its portfolio, Adani Transmission quickly became a major player through major mergers and acquisitions in 2016-17.
At present, about 8 TBCB projects totaling more than Rs 1,000 crore are under bidding at different stages. Foreign transmission companies, including China Southern Power Grid, have expressed their intention to enter Indian transmission industry in the bidding of the latest round of TBCB projects.
Policy and regulatory framework
The Indian government constantly adjusts its policy and regulatory framework to keep pace with changing industry needs.
In this context, the government has taken measures to break the monopoly of India's State Grid Corporation in the field of transmission, to ensure a more fair competition environment with private-owned enterprises, to modify guidelines for transmission system planning, to encourage early completion of projects, to review the standard tender documents For TBCB, and so on.
In addition, the Central Electricity Regulatory Commission also circulated relevant regulations, introduced ancillary services and forecast the wind / solar output of interstate developers.
Renewable energy integrationWith the Indian government announcing its plan to increase renewable energy from about 400 million kilowatts to 17.5 billion kilowatts by 2022, the pressure to develop the related power transmission infrastructure has increased. In this context, the State Grid Corporation of India is implementing the first phase of the Green Energy Corridor project and the second phase of the project.
Phase I of the project plans to add 17,000 km of transmission lines and 34,650 MVA of substation capacity to the interstate and the state to support 33 GW of solar and wind power.
At the same time, the second phase of the project will help to deliver electricity to the needed areas from the upcoming 20,000 megawatts of solar parks.
Cross-border InternetIndia is actively building cross-border transmission lines with SAARC member countries to achieve the goal of electricity trading and a unified regional power grid. India currently has cross-border grid interconnections with Bangladesh, Bhutan, Myanmar and Nepal.
At the same time, there are five more cross-border grid interconnections in India under construction, one each from Bangladesh and Nepal and three from Bhutan.
In addition, the grid interconnection plan between India and Sri Lanka and Pakistan is under discussion.
Interstate differencesOf the 24 utility companies surveyed by the Indian Institute of Infrastructure, state-owned transmission companies in Gujarat, Maharashtra and Karnataka have the largest share. State-owned transmission companies in Uttar Pradesh and Rajasthan are the only ones with a 765-kilovolt grid.
In terms of substation capacity, state-owned transmission companies in Maharashtra, Gujarat and Uttar Pradesh have the largest share (in this order). Transmission losses of state-owned transmission companies range from 0.85% (Delhi) to 5.18% (Uttar Pradesh).
In line with the draft of the State Power Administration's 2016 National Electric Power Plan (NEP) of the Central Electricity Authority, 105,580 km of additional lines were added in the 13th FYP (2017-22) and the substation capacity increased by 292,000 MVA, which required an investment of 2.6 trillion rupees.
Indian Infrastructure Research estimates that India's transmission network infrastructure will reach 577,797 km and 1,291,796 MVA by 2025 and will invest 566-59 billion rupees annually in 2017-25.
