Green Blackout: Toronto July 5th 2010

Wednesday, July 14th, 2010

I commented several times on the Toronto blackout of July 5th on CBC television and radio on July 6th. Attached is an article, called “Green Blackout”, expanding upon the points raised in the CBC interviews, particularly the role of careless environmental advocates in undermining the reliability of Toronto’s electricity transmission system. The article appeared in the on-line edition of the National Post July 7th and the print edition July 8th. The article was subsequently discussed by various media outlets including by John Tory on CRFB radio on July 9th.

Ontario Wind Farm Productivity and Variability by In-service Year

Friday, July 2nd, 2010

This post provides data current to June 30, 2010 on the productivity and variability of output of Ontario’s wind farms. The tendency of more productive wind farms to produce power with greater annual variability of output is observed. An error in the data reported in the April 6, 2010 edition of the report with respect to Prince Farm is noted and corrected in this edition. The life-to-date capacity factor of Ontario’s large wind farms considering only full power years is 29.0%.

Renewable Energy Gold Rush Through the Roof

Sunday, May 16th, 2010

The attached analysis surveys the renewable electricity supply projects proposed to the Ontario Power Authority (OPA) under the provincial government’s Feed-In Tariff program, the contracts offered by the  OPA as of early May 2010, and the consumer impacts.

Review of “A rational framework for electricity policy” by Dr. Jan Carr

Thursday, April 8th, 2010

The attached review considers an article in the Journal of Policy Engagement (April 2010, Volume 2/Number 2) authored by Dr. Jan Carr, a leading electricity sector leader in Canada. The review posits a confluence of factors that created the conditions for the collapse of the historic consensus that the purpose of Ontario’s power system was to serve consumers and fostered the rise of the Green Energy Act.

Samsung Secret Deal with McGuinty Government: News Update

Saturday, November 7th, 2009

Renewable energy developers who have been playing by the Ontario government’s irrational but at least codified Green Energy Act Feed-In Tariff rules have reacted vigorously to information first published on this web site about a secret deal initiated on the government side by Smitherman that would allow the international electronics giant Samsung rights of primus noctis. The revolt against Smitherman appears to be lead by Dwight Duncan and Sandra Pupatello. Smitherman was expected to appear at the prominent APPRO conference (November 17/18) but has withdrawn. The best case for the government is for Samsung to withdraw. Although the list of wind industry lobbyists is very long on the Ontario government’s Lobbyists Registration Act web site, there is still no trace of Samsung’s name on the list. Watch for this news showing up in the Toronto Star in the middle of next week.

Wind Power Can Be Wonderful

Tuesday, September 29th, 2009

Exploiting wind power can be a triumph over adversity.

There may be ways to turn industrial wind power from a subsidy sponge into a contender.

Even the analysis of wind power can be beautiful.

Wind power can be fun (albeit costly in this instance).

Presentation Arguing Against Feed-In Tariffs (FIT)

Thursday, September 24th, 2009

The attached presentation, to a conference in Toronto held September 21st, argues that the Ontario FIT program is uneconomic, politically vulnerable, and likely to be short-lived. I specifically identify an urgent need for the IESO to present analysis on when wind power is likely to take over as first contingency for the purposes of operating reserve and for the OPA to present an update of the Integrated Power System Plan, so that the outlook for power development and power prices can be estimated within the uncertainty of the constituent elements.

Greener Power Ingredient: Coal

Sunday, July 5th, 2009

Many people debating greenhouse gas controls think they know that coal is our worst electricity source with respect to carbon dioxide emissions and that natural gas is about half as bad. Although replacing coal power with gas-fired power seems like an environmental winner, this simplistic generalization is often wrong. Eliminating coal-fired electricity will require replacing it with gas and because of the characteristics of our gas-fired stations, Ontario’s carbon dioxide emissions will rise.

This essay also addresses the suggestion from many environmental groups that Ontario should seek to maximize the use of gas in the form of high-efficiency cogeneration as opposed to mid-efficiency combined-cycle generators and low-efficiency simple-cycle generators. I note that the more cogeneration Ontario adds, the lower the potential penetration of wind power the power system can tolerate.

Transforming Ontario’s Electricity Paradigm: Lessons Arising from Wind Power Integration

Wednesday, May 20th, 2009

In the following keynote address to Professional Engineers of Ontario, Annual General Meeting, May 9, 2009, Tom Adams outlines the challenges ahead for integrating renewable energy into the Ontario power grid. Data is presented showing how wind power production and electricity usage are out of sync, how winter wind power output is concentrated on the warmer winter days when load tends to be low, how distance between wind farms provides limited smoothing benefit, why it is inaccurate to claim that the wind is “always blowing somewhere”, and how wind output from distant farms can be strongly correlated even sometimes when measured on a 5 minute time scale. Knowledge gaps on wind integration current as of the date of presentation are identified.

WIND POWER IN ONTARIO: QUANTIFYING THE BENEFITS OF GEOGRAPHIC DIVERSITY

Wednesday, May 20th, 2009

Using Ontario wind power production data, this study quantifies the benefits of positioning wind farms in geographically diverse locations to mitigate variability and smooth wind power’s contribution to electricity generation. Wind farm outputs are cross-correlated and graphed against the distances separating the farms. Results confirm that correlations between wind farm outputs decay with distance, but remain positive. Results agree with European studies but suggest that distance provides less smoothing of output in Ontario than in Europe. However, results disagree with aspects of a study of wind power integration in Ontario conducted by General Electric in 2006.

This study was co-authored by Tom Adams and Francois Cadieux. It was peer reviewed and published as part of the Engineering Institute of Canada 2nd Climate Change Technology Conference, May 12-15 2009, held at McMaster University.
