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 is 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.

According to the India government (October 2020), the power station is planned for commissioning in 2022.[7]

Financing

It was reported in 2019 that the Power Finance Corporation is funding the project, at an estimated total investment of Rs98bn (£1.07bn).[8]

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.[9]

The 2014 environmental clearance states coal for the power station will be imported.[10]
