The Kelanitissa Power Station is a power generation complex consisting of two separately owned facilities, located on the south bank of the Kelani River in the northern part of the city of Colombo, Sri Lanka. The entire power facility is capable of producing a total of 550 MW of power at a given time, a significant amount when compared to the total installed capacity of nearly 3,932 MW in the year 2014.[3]

AES Kelanitissa Power Station

The privately owned facility, known as the AES Kelanitissa Power Station, is a 168 MW diesel fuel fired combined cycle power station.[4][5] It is owned by AES Kelanitissa Private Limited, a subsidiary of AES Corporation. It consists of three generation units. Unit-1 is a GEPG9171E gas turbine with a nominal output of 115 MW, while Unit-2 is a 55 MW steam turbine manufactured by Bharat Heavy Electricals Limited. The third unit is a CMI-certified Larsen & Toubro-designed and Doosan Babcock manufactured LTC heat recovery steam turbine.[4] Construction works were done by Larsen & Toubro.[2]

The private facility began combined-cycle operations in the 2003 and since September 2005 it runs in combined-cycle mode. Like all power stations in Sri Lanka, power generated by the power station are sold to the Ceylon Electricity Board under a 20-year take-or-pay power purchase agreement. The low-sulfur diesel is supplied through an existing pipeline by the Ceylon Petroleum Corporation, with 20,000 tons, or the equivalent of 28-days of full capacity operations, stored in case of any fuel shortage. The plant is currently running on a 20-year contract, which ends on October 10, 2023.[4]

CEB Power Complex

The government-owned facility, simply called the Kelanitissa Power Station, consists of older conventional power station and newer combined cycle power station. It is owned and operated by the Ceylon Electricity Board.[6] The older station has five open cycle diesel-fired gas turbines rated at 20 MW each, all of which were commissioned between 1980 and 1982, and a single Fiat PS-GT7 gas turbine rated at 115 MW, commissioned in August 1997.[1][6] One 20 MW open cycle gas turbine and two 25 MW oil-fired conventional boiler/steam turbines were decommissioned after opening the new combined-cycle stations. The old power station is used as a peak-load power station. The 115 MW Fiat Avio plant GT7 was sent for renovation in Italy in 2011 after which it is used as a stand-by generator.[7]

The newer 165 MW naphtha-fuelled combined cycle power station was commissioned in August 2002.[1] It consists of one 110 MW gas turbine, one 55 MW steam turbine, and one exhaust heat recovery boiler.[8] The project was funded by the Overseas Economic Cooperation Fund of Japan.[6] Initially the station was to have 150 MW capacity with two or three 37–67 MW units, but later the single unit with higher capacity was chosen.[8]

Incidents

In 2004, fire broke out at AES Kelanitissa Power Station. The power station was shut down for restoration in 2004–2005.[4]

On 28 October 2008 at 23:30, the Liberation Tigers of Tamil Eelam (LTTE)separatist group launched two bombs in an aerial attack on the power station, causing a fire and damaging the 115 MW government-owned Fiat unit. It took six months to restore the unit while one person was reported to have died, possibly due to shock. The attack was carried out using a Czech-built Zlín Z 42 single-engine trainer aircraft.[9][10]

On 21 April 2012 at about 03:00, a fire erupted at the power station complex, damaging the main switchboard for the plant's power generation machinery. Power generation was ceased, but did not trigger any blackouts due to alternative sources being available at the time. Six employees of the power station who inhaled noxious fumes as a result of the fire were hospitalized.[11][12]
