NorochcholaiCoal Power Plant

Sri Lanka’s first coal-fired thermal power plant and the largest power station is implemented as a venture of Ceylon Electricity Board with the aid of EXIM Bank of the Republic of China. Located 100m inland from the shoreline, the construction was undertaken by the CMEC (China Machinery Engineering Corporation) and the total estimated cost of the project was USD 1.35 billion. The contract for the project was signed in 2006 and the first phase of the power plant, 300 MW was commissioned in 2011. The second phase completed adding another 300 MW in 2014 while the third phase added another 300 MW, making the total power generated through the Norochcholai power plant 900 MW. The first phase also included the construction of a 115km transmission line that connected the power plant to the national grid through the Veyangoda substation. A jetty that extended 4.2km into the ocean was also constructed. Nearby villages include Narakkalli and Penaiyadi on the Kalpitiya peninsula.

Air Pollution in Norochcholai:

The Lakvijaya Power Station which is also known as the Noracholai Power Station generates a significant amount of Sri Lanka’s total electricity production. The power station is in Noracholai, in the Kalpitiya Peninsula. Emissions from the 900MW coal power plant in the Kalpitiya peninsula is much above permissible standards possibly due to frequent breakdown, intermitted operations and unexpected storage of fly-ash in open pits.

The power plant also gives rise to a large amount of solid waste, heat waste and water pollution due to the release of heated water. This will have long term environmental impacts.

Our Instrumentation work near Coal Power Plant Norochcholai:

We installed an air quality monitor and two automated weather instruments on a field where Lakvijaya Power Station is located to monitor the air quality around, Fine particulate matter, CO2 levels, Indoor and Outdoor
Air Quality Index, Temperature, Humidity and the instrument send the data online to our cloud and the website. The Automated weather instruments will archive the data for 3 months in its memory and the other weather instrument sends the data variables like solar radiation, precipitation, air pressure, wind speed and direction to online.
