“GMR Vasavi Diesel Power Plant”的意思、由来-开放百科全书

GMR Vasavi Diesel Power Plant, owned by GMR Power Corporation Limited, is a private-owned power plant located in Basin Bridge, Chennai. It is a 200-MW LSHS (low sulphur heavy stock) fuel (processed from the residue of indigenous crude) power plant of the GMR Group.^[1] The plant is based on two-stroke diesel engine technology from MAN B&W, Germany. It is the state's first plant commissioned by the private sector.^[2] The plant was decommissioned in 2018.

History

The 196-MW liquid fuel-fired power plant was commissioned in 1998 by the GMR Power Corporation on a 29-acre land leased by the Tamil Nadu Generation and Distribution Corporation for 20 years in March 1997.^[2] The entire power generated at this plant is supplied to the Tamil Nadu State Electricity Board.^[2] It was inaugurated by the then Chief Minister M. Karunanidhi in March 1999. Initially diesel was used as fuel, and later the plant used low sulphur heavy stock (LSHS). The Tangedco entered into a 15-year power purchase agreement with the plant. When it expired in 2014, it continued to purchase power from the plant till February 2015. After this, the agreement was not renewed.^[2]

The plant

Conservation

To prevent harmful pollutants from escaping into the atmosphere, the plant incorporates reverse osmosis for the final stage of purification. It also has a water conservation plant that processes about 5 percent of Chennai's sewage to produce water that is required to operate the plant, which is said to be the first of its kind in the country. The plant treats 7,200 cubic metres of raw sewage per day from Chennai MetroWater Supply and Sewage Board to produce 5,400 cubic metres of clean water for its own use.^[2]

Expansion

Phase-I of the project consisting of 4 X 50 MW liquid fuel-based (diesel) power plant is in operation since February 1999.^[3] In 2010, the plant planned conversion of Phase I project to a gas-based plant, in addition to initiate Phase II, which consists of additional 120 MV gas-based combined cycle power plant. The expansion plans requires additional land requirement of 2.5 acres, which is within the existing premises.^[9]

Natural gas requirement for expansion is estimated at 0.60 MMSCMD, to be obtained from Krishna-Godavari basin. Natural gas required for conversion of existing diesel-based plant is estimated at 1.1 MMSCMD. About 3.48 MLD of water required for the expansion will be obtained from treated sewage water within the plant premises. An estimated 4.8 MLD of water will be required for conversion.^[4]

There is also possibility of switching over the fuel of existing units from heavy oil to pyrolysis oil obtained from bio mass or urban garbage gasification.

These power generation units can be put to use for grid reserve service.^[5]^[6]

Significance

The power plant remains significant as it catered to the requirements of vital civic utilities such as the Madras High Court, the Government Hospital, Secretariat, Central Railway Station, Egmore Children's Hospital and many important residential areas during emergencies.^[7]

Awards

The plant has received ISO 14001 and OHSAS 18001 certifications from Det Norske Veritas. It has also received the Dr. M. S. Swaminathan Award for Environmental Protection for conserving the environment.^[2]

Decommissioning

In 2018, the plant was decommissioned owing to high cost, with dismantling of the plant beginning in May 2018.^[7]
