Abstract
The construction of Alberta's $695 million, 500 MW Genesee 3 coal-fired power plant was discussed. The power plant offers notable improvements on environmental performance compared to its predecessors, Genesee 1 and Genesee 2. Efficiencies have been improved by 18 per cent over the average coal-fired facility in Alberta. The construction of Genesee 3 was a joint venture between Epcor and TransAlta. Mining is done by Luscar in a joint venture with Epcor. Planning for Genesee 3 began in 1998 at a time when innovation was needed to meet the increasing standards for environmental performance and to meet the objectives of the Kyoto Protocol. The solution was a super critical pulverized coal technology which uses higher steam temperatures and higher steam pressures to make more use of the energy available and lower the amount of coal required. As a result, Genesee 3 decreased the amount of nitrogen oxide emissions by about 50 per cent compared to its predecessors. Emissions of sulphur dioxide were lowered from 258 to 180 nanograms per joule. Genesee 3 also capture 99.9 per cent of particulate matter. The company also committed to offset the amount of carbon dioxide produced to the equivalent of natural gas combined cycle plants by buying emission credits. In order to meet energy demand, the mine was expanded from 3.5 to 5.2 million tonnes per year. Current reserves indicate a mine life of about 50 years. The mine uses conventional dragline mining, but the dragline sits on a bench and is used to mine the coal and pile it on the bench as well. Additional shovels and 240-tonne trucks will be purchased by 2010 to handle increased loads. Disturbed ground is fully reclaimed within 4 to 5 years of mining. The power plant includes a circuit with a super critical pulverized coal technology, low NOx burners, flue gas desulphurization units to lower sulphur dioxide, and a baghouse. In 2005, Epcor acquired 744 MW of power plants throughout North America, ranging from wind, natural gas, waste wood and hydro. Epcor also operates 1,300 MW of coal-fired capacity and is pursuing other environmentally-sound, coal-fired power plants. 2 figs.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
