Canada approves 110 MW Boundary Dam CCS plant
The provincial government of Saskatchewan in Canada has consented to SaskPower’s application to construct the Boundary Dam Integrated Carbon Capture and Storage (CCS) Demonstration Project, which will see the transformation of an aging generating unit into one of the world’s first commercial–scale CCS plants.
The C$1.24bn ($1.3bn) project near Estevan will have an installed capacity of 110 MW.
SaskPower has appointed SNC Lavalin to oversee EPC activities at the Boundary Dam project and will chosen Cansolv, a wholly-owned subsidiary of Shell Global Solutions, to provide the technology for the carbon capture process. Hitachi will supply a state-of-the-art steam turbine designed to fully integrate the coal fired plant with carbon capture technology.
The CO2 will be used for enhanced oil recovery in nearby oil fields and the Boundary Dam project will also feature capture of SO2 to be used in the production of sulphuric acid. Plant commissioning is due in 2014.
Entergy move to independent grid system could save customers $1bn
An Entergy Corporation study has calculated that joining the Midwest Independent System Operator (MISO) could save its customers up to $1bn between 2013 and 2022.
MISO is an independent, non-profit, Regional Transmission Organization in 13 US states. The study compared savings arising from joining MISO with proposals from Southwest Power Pool (SPP).
With the additions of Entergy, slated for December 2013, MISO could operate a grid network extending from the Canadian border to the Gulf of Mexico.
Siemens wins order for 200 MW open-cycle power plant in Peru
Siemens Energy has been awarded an $80m contract for turnkey construction of the 200 MW Santo Domingo de los Olleros open-cycle power plant in Peru.
The award was made by Peru-based Termochilca SAC which plans to locate the 200 MW plant in the Chilca district in Cañete province, Lima region. The plant is expected to open in late 2012. Siemens will engineer, procure and construct the plant as part of the contract.
It will supply an SGT6-5000F gas turbine, generator SGEN6-1000A and the entire electrical and SPPA-T3000 I&C equipment.
Colombia awards 2400 MW hydro plant to Hidroeléctrica
Colombian authorities have awarded the concession for a 2400 MW hydropower plant to Hidroeléctrica Ituango that could see the energy provider becoming the largest in the country.
The capacity being added would be sufficient to cover a fifth of Colombia’s energy demands.
Through this agreement, which is the first one of its kind in Colombia, “we have been able to gain financing for a hydroelectric project through a concession,” said Luis Guillermo Gómez Atehortúa, general manager at Hidroituango.
The investment will reach $3bn with the large-scale hydro project being built on the Cauca River, covering an area 79 km long and 700 metres wide, and at a height of 225 metres.
EPA emissions agreement to cost TVA $3-5bn
The Tennessee Valley Authority (TVA) must invest between $3bn-$5bn in emission control technologies for 11 of its coal plants in three states as part of settlement agreement with the Environmental Protection Agency.
The TVA settlement resolves alleged Clean Air Act violations at plants in Alabama, Tennessee and Kentucky. The emissions control technology is expected to address 92 per cent of the company’s coal capacity, reducing emissions of nitrogen oxide by 69 per cent and sulphur oxide by 67 per cent from 2008 levels.
Solar plant bags $1.2bn US loan guarantee
The California Valley Solar Ranch, a 250 MW PV plant that NRG Solar is buying from SunPower, has been offered a $1.187bn loan guarantee from the US Department of Energy.
Construction is expected to start on the solar farm in the second half of 2011, subject to permitting and financing. A portion of the plant is expected to come online by the end of 2011 with the rest beginning operations in 2012 and 2013.
Argentina: Electricity demand rose to a record high of over 20 900 MW in March as a result of a recent heat wave, however this still leaves a reserve margin of 2000 MW or 20 per cent.
Ecuador: A consortium including Mexican state power company CFE and local firms has been awarded a contract worth $72.4m to oversee the turnkey construction of the 1.5 GW Coca Codo Sinclair power project.
Honduras: China’s Sinohydro has signed a $50.5m contract to begin construction of a 140 MW hydropower plant – the first of three planned plants on the Patuca River that will have a total capacity of 524 MW.
Jamaica: Office of the Utilities Regulations has delayed the construction of a 480 MW programme to increase national power capacity to February 2012.
Mexico: Renewable generation capacity will reach 4.5 GW by 2012 and at least double that by 2025, according to the Energy Ministry, in response to criticism from the Solar Association.
Peru: Empresa de Generación Eléctrica San Gabán has put the cost of building the 187 MW San Gabán III hydroelectric plant at $335m.
USA: The Vermont Electric Co-op has rejected a contract to buy power generated from the Vermont Yankee nuclear power plant at below market prices. The plant is scheduled to shut in 2012 but owner Entergy is suing the state of Vermont to keep the plant open.
USA: Duke Energy will install a 36 MW energy storage and power management system designed by Xtreme Power at its 153 MW Notrees Windpower Project in Texas. The battery storage system is due to come online by late 2012.
USA: Progress Energy said a build-up of hydrogen used as a generator coolant caused an explosion in March that killed a maintenance worker at the 600 MW L.V. Sutton coal fired plant. The plant was offline at the time and Progress believes that a fan or a light caused the ignition.
