The Tuticorin Thermal Power Station (TTPS) in Thoothukudi district has added a feather to its cap after it achieved a record of sorts recently by generating power at the least cost among the other thermal power stations in the State, sources said.
Boiler tubes in TTPS, which has five units with a generation capacity of 210 MW each, were primarily designed to handle domestic coal, which contains 40-42% ash as compared to imported coal which reportedly has just 8 per cent content. “Since foreign coal has higher calorific value than indigenous coal, less amount of coal is enough for generation. Hence, power generation [in TTPS] relied on 25 per cent imported coal, mostly from Indonesia. On a daily average, it requires about 17,000 to 18,000 tonnes of coal for generation from these five units,” sources said.
Moreover, TTPS also made another achievement after having surpassed its generation target set by the Central Electricity Authority. During the fiscal year of 2018-19, a target of 5,678 million units was set, but it exceeded the target, generating 6,306 million units, sources pointed out.
Except for the third unit of this plant that tripped on 28th last month, the rest have been functional without suffering any breakdown.
