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.
