OPG Controversies: Coal Phase-Outs and Nuclear Refurbishment Challenges
Ontario Power Generation (OPG) has played a pivotal role in powering the province, but its history is marked by significant operational and management challenges. From the environmental impact of massive coal plants to the complexities of nuclear reactor refurbishment, the company has frequently found itself at the center of political and public scrutiny.
The Transition from Coal-Fired Power
Before transitioning to cleaner energy sources, OPG operated several coal-fueled generating stations that were among the largest sources of air pollution in Canada. The Nanticoke Generating Station was particularly controversial; as North America's largest coal-fired plant, it possessed a massive 3,900 MW of generation capacity. While it was relatively clean per megawatt produced, its sheer scale made it the single largest source of air pollution for northern New York state and southern Ontario.
The Lambton Generating Station also drew criticism as the second-largest air polluter in the province. In 2003, the Liberal government led by Dalton McGuinty campaigned on a promise to phase out coal by 2007. However, due to electricity demand and operational constraints, the final coal fires in OPG stations were not extinguished until 2014.

OPG's nuclear portfolio has also been a source of contention, specifically regarding recovery times and project management. Following the Northeast blackout of 2003, the company faced criticism for the slow return to service of its nuclear stations. Most reactors had tripped and were allowed to poison out—a technical state where fission product buildup prevents the reactor from restarting immediately—meaning they required several days to return to the grid.
The Pickering A Unit 4 Crisis
One of the most significant management failures occurred during the refit of Unit 4 at the Pickering A Nuclear Station. The project suffered from a lack of complete scope analysis and an underestimation of the work's complexity, leading to the project finishing three years behind schedule and significantly over budget.
The fallout was severe. In late 2003, the provincial government fired OPG's three most senior executives and accepted the resignations of the entire board. This prompted an independent review committee, chaired by former Deputy Prime Minister John Manley and including Peter Godsoe and Jake Epp, to examine OPG's corporate governance, structure, and the viability of refurbishing Pickering A Units 1, 2, and 3.
The subsequent refurbishment of Unit 1 was more successful, adhering closely to its budget and schedule before returning to service in November 2005 with 542 MW of capacity. Conversely, the business case for restarting Units 2 and 3 could not be justified, and they remained offline.

In more recent years, OPG has faced criticism regarding its spending and executive compensation. In December 2015, the Auditor General of Ontario revealed that the Thunder Bay station was importing wood products from Europe for biomass energy. This practice drove the cost of electricity to $1,600 per MWh—roughly 25 times higher than other biomass generators. In response, Minister Michael Gravelle stated that OPG would seek local biomass fuel suppliers.
Additionally, the 2015 hiring of CEO Jeffrey Lyash sparked public debate. Amid rising electricity costs for consumers, Lyash's compensation package—a base salary of $775,000 with the potential to reach $1.55 million including performance bonuses—was viewed by critics as excessive.
[ไม่มีภาพประกอบ]Key Facts
- Nanticoke Generating Station: Once North America's largest coal plant with 3,900 MW capacity.
- Coal Phase-out: Promised for 2007, but officially completed in 2014.
- Pickering A Unit 4: Suffered massive cost overruns and a three-year delay, leading to a total board and executive overhaul.
- Pickering A Unit 1: Successfully returned to service in 2005, adding 542 MW to the grid.
- Biomass Costs: European wood imports at Thunder Bay once cost $1,600 per MWh.
| Issue | Primary Cause | Outcome/Resolution |
|---|---|---|
| Coal Pollution | Massive capacity at Nanticoke and Lambton | Complete phase-out by 2014 |
| 2003 Blackout Recovery | Reactors "poisoning out" | Delayed reconnection to the grid |
| Pickering A Unit 4 Refit | Poor scope analysis and management | Executive firing and independent governance review |
| Thunder Bay Biomass | Importing fuel from Europe | Search for local biomass suppliers |
Frequently Asked Questions
Why did it take until 2014 to phase out coal if the goal was 2007?
While the government set a target of 2007, various operational challenges and electricity demand requirements made it impossible to shut down the plants earlier.
What does it mean when a nuclear reactor "poisons out"?
Poisoning out occurs when certain isotopes build up in the reactor core, absorbing neutrons and preventing the nuclear chain reaction from restarting immediately. This necessitates a waiting period of several days before the reactor can return to service.
What happened to the board of OPG after the Pickering A Unit 4 delays?
Due to the significant budget overruns and schedule delays, the provincial government fired the three most senior executives and accepted the resignations of all remaining board members.
Why were Pickering Units 2 and 3 not restarted?
Following the review of the refurbishment process, it was determined that a viable business case could not be made to justify the cost of restarting these specific units.
How expensive was the imported biomass fuel at the Thunder Bay station?
The imported European wood products pushed the cost of electricity generation to $1,600 per MWh, which was 25 times more expensive than other biomass generators.
