Ennore SEZ Super Critical Thermal Power Project (Vayalur)

From Global Energy Monitor

Ennore SEZ Super Critical Thermal Power Project (Vayalur) is a 1,320 megawatt (MW) coal-fired power station in Tamil Nadu, India, which has been proposed by the Tamil Nadu Generation and Distribution Corporation (TANGEDCO).

The power station is not to be confused with the Ennore Thermal Power Station.

Background

TANGEDCO has proposed to build two supercritical 800MW units on a reclaimed ash disposal area of the North Chennai Thermal Power Station. The plant is proposed to be built on 500 acres of land owned by the Tamil Nadu Electricity Board near the village of Vayalur, Tiruvallur district, Tamil Nadu, India.[1][2]

The project received environmental clearance for a 2 x 800 MW coal plant in 2014.[3] The capacity of each unit was, however, reduced to 660MW while calling engineering, construction, and procurement (EPC) tenders for the project in the same year.[4]

According to the India government (March 2016), the project was under construction with a planned commissioning of 2018-2019. The EPC contract was awarded to Bharat Heavy Electricals (BHEL).[5]

In December 2016 the India government reported that work at the site was held up from October 2015 onwards due to a court case filed against TANGEDCO by one of the EPC bidders. On October 18, 2016, the court ruled in favor of TANGEDCO and work on the site reportedly resumed on November 2, 2016.[6]

Planet satellite photos show construction did not substantially begin until June 2018, and then advanced through October 2018.

In 2019, TANGEDCO got a two year extension from the government to finish construction of two slow-moving thermal power plants at Ennore with a combined capacity of 1,980 MW. [7] In 2020, a second extension was granted for the project until 2024.[8]

According to the government's Broad Status Report in October 2020, the power station was planned for commissioning in 2022.[9] By November 2021, the date was pushed back to 2023.[10] By May 2022, it was delayed to 2024.[11]

Opposition & permitting developments

A suo moto case (No.162/2021) was registered by the National Green Tribunal against various projects including the Ennore SEZ project based on news published in Times of India dated July 1, 2021.[12][13] The NGT (Southern Zone, Chennai) constituted a committee and instructed it to look into the issues and submit a report. Accordingly, the NGT Committee recommended that "TANGEDCO shall resume the activities pertaining to NCTPS Stage-III and Ennore SEZ power plants within [Coastal Regulation Zone (CRZ)] area in Kosasthalaiyar River/Buckingham Canal/Backwaters only after obtaining amendment to the existing CRZ clearance from MoEF&CC."[14][15]

Financing

It was reported in 2019 that the Power Finance Corporation is funding the project, at an estimated total investment of Rs98bn (£1.07bn).[16] As of December 2020, 55% of financing had been secured.[17]

Coal supply

TANGEDCO has stated that coal for the project would be 30% imported coal and 70% domestic through Ennore Port.[1] TANGEDCO states that the project would require 5.46 million tonnes per annum of coal. TANGEDCO proposes that 3.82 million tonnes per annum be sourced from the Kalinga Block, Talcher, Mahanadhi and IB Valley and 1.64 million tonnes per annum from unspecified overseas sources.[18]

The 2014 environmental clearance stated coal for the power station would be imported.[19]

In January 2022, with Ennore SEZ and other coal projects set to take off with a generating capacity of 5,700 MW, Tangedco bid for two coal blocks – Meenakshi coal block in IB Valley and Bankhui coal block in Talcher – to meet the growing needs of the state.[20]
