No deal on Alcan power in BC: major economic, environmental opportunities slip by

by Stephen E. Aplin • February 22, 2007 • 0 Comments

The British Columbia Utility Commission (BCUC) recently shot down a proposal that would see BC Hydro buying up to 130 megawatts of carbon-free electricity at a premium rate (7.1 cents per kWh) from Alcan’s Kemano hydro facility near Kitimat. Their…

Sunsetting wind power program spells opportunity for major emission reductions in Canada

by Stephen E. Aplin • December 8, 2006 • 0 Comments

In previous posts I have suggested extending the Wind Power Production Incentive (WPPI) to include other low- and non-emitting forms of electricity generation, including nuclear and coal gasification. But now I wonder if instead of a subsidy like the WPPI,…

Coal-based power generator contemplates acquiring nuclear, IGCC plant

by Stephen E. Aplin • October 29, 2006 • 0 Comments

In my September 14 post, I predicted that coal-based generating companies operating in carbon trading areas would begin acquiring nuclear assets as a way of hedging against carbon prices. Platts Commodity News quotes an NRG Energy official as saying the…

**Table A3** Should we replace nuclear plants with natural gas-fired ones? This table compares actual Ontario grid CO₂ emissions from the last hour with those from a grid in which gas has replaced nuclear.
Actual Ontario grid	Gas replaces nuclear
799	6,069
45.83	348.08
Tons CO₂ CIPK, grams If gas had replaced nuclear last hour, Ontario power plants would have dumped enough CO₂ to fill Rogers Centre 2.1 times. As it was, 799 tons were dumped, which would fill Rogers Centre 0.3 times.
