The green mirage: Toronto school board gets free roof repairs for solar panels — or do they?

Toronto School Board flunks out
Toronto School Board flunks out

Canada’s largest school board, the Toronto District School Board (TDSB), is getting an F on management practices.  Ontario’s Ministry of Education and Ministry of Energy must also receive a failing grade.

It starts with Toronto’s public schools having leaky roofs.  The TDSB, with much fanfare May 2011, found the Holy Grail when they struck a deal with AMP Solar Limited Partnership for solar panels on school roofs.  TDSB thought the deal with AMP would result in free roof repairs on 450 schools, and, after AMP recovered the cost of the repairs, TDSB would also receive 14.5% of the solar power revenue generated from the Feed-In Tariff or FIT contracts they hoped to obtain from the OPA (Ontario Power Authority).  On paper it sounded wonderful; TDSB’s Director of Education Chris Spence said,  “This is a win-win for everyone involved.”

What he meant was, it would be a losing proposition for Ontario’s ratepayers.

What has happened since that announcement shows someone didn’t do their math homework or anticipate what might go wrong.

One year later: there were delays as the rules under the FIT program changed, creating lower prices for roof-top solar, and then McGuinty prorogued the Legislature.  The Toronto Sun quoted Chris Bolton, TDBS’s chair, confessing the Board didn’t have an alternate plan.  The story went on to say the Ontario government “encouraged” the TDSB to turn to FIT as a resolution to its roof repair backlog.   It is not clear if that suggestion came from the Ministry of Education or the Ministry of Energy.  If it was, it was as a neat budget gambit to fool the taxpayers while sticking it to the ratepayers.   Three weeks prior to the Sun article the Ministry of Education froze new construction approvals, “citing concerns the TDSB was going over budget on building projects and in danger of not wiping out an existing $50 million capital deficit.”

A few “snags”

Fast forward July 25, 2014: the reporter who wrote the Toronto Sun story wrote one for the National Post  headlined  “Solar panel upgrades for public schools hit snags”.  The article infers “the costs” to repair the roofs are “higher than first pegged” and goes on to explain, “That’s because of greater-than-expected costs to the board’s private partner-School Top Solar LP-for roofing, installing the panels and fees to Toronto Hydro for hooking up to its power grid.”  It is unclear who School Top Solar LP is—the original TDSB partner was AMP Solar Limited Partnership, but perhaps they flipped the project to take a nice profit (as has happened with so many companies) that have obtained FIT contracts).

The result of this wonder story is that the most TDSB will get out of this free deal will be to replace one-sixth (720,000 sq. ft.) of the 4.3 million square feet of roofs.    They can also kiss goodbye to the 14.5% energy revenue Chris Spence thought they would get.

Let’s see where the mistakes were made. First, the math on the 66 MW that will be installed: based on the original roof-top solar prices ($700 per megawatt hour), the 66 MW could have generated in excess of $40 million annually and $806 million over the 20-year life of the contract. The developer (AMP) claimed the 66 MW would produce enough electricity to power 6,000 average homes, which means 57,600 megawatt hours (MWh) of power yearly.

Now the roof repair costs: roof replacement repairs to the 4.3 million square feet would run to $8 or $9 per sq. ft., meaning total costs would be in the $40 million range.  Capital cost of solar per MW is $5 million (approximately) as estimated by the U.S. EIA, so 66 MW would have cost $330 million making total costs (including roof repairs) about $370 million and recovery of the cost outlays (including maintenance) should have taken nine to ten years.

If it looks too good to be true, maybe…

The reduction in the FIT rates threw the “free” roof idea into jeopardy. It now looks like the TDSB will have to go cap in hand to the Minister of Education, Liz Sandals, if they want those leaking roofs fixed, without making the Board’s $50-million capital deficit disappear.

What’s funny is that now, as reality hits, a few of the education board trustees interviewed for the National Post said they actually want to blame the school principals (some of them had requested adjustments to the placement of the equipment used to hook up the panels to Toronto Hydro’s electricity grid).

Perhaps Ms. Sandals will solve the TDSB dilemma by getting the teachers unions to back down on their demands for raises and pension benefits until the roof leaks have been plugged!

This is another example of the many logic failures brought to Ontario by the Liberal government and its push for renewable energy on a large-scale!

yet again proponents pull their numbers out of a hat. They claim this project would have powered 6,000 homes. No one asked for proof of their math. A project on this scale would be less than a third of that number.
average house uses 10,800 kwh annually according to Hydro One
66 MW = approximately 151,800 panels
x 1 square meter x 129 kw per panel (for this longitude & latitude) = 19,582,200 divided by 10,800kw = 1,813 homes


New math or no math at all? I hope it was only the TDSB that this nonsense happened to.


I was sceptical when I first heard about the TDSB deal with solar panels. These things never work out. Educators and bureaucrats are not good at math and do not understand how the real world works.

Wind Concerns Ontario

Hi Peggy, I think the real point is not whether people are “good at math” but whether they stopped to do a simple analysis of the promises being made about that particular venture. Parker’s goal was to note that here is a body charged with management of many millions of taxpayer dollars, and didn’t do its job. The “greenwashing” has caused decision-makers to assume that everything to do with renewable power is good.


Ok, to be clear, as a teacher/educator who has been in this battle for ~7 years along with others, some of whom are your toughest warriors against IWT and who have stood side-by-side with many of you, there needs to be a stop to disrespectful statements, ” are not good at math and do not understand how the real world works”…really?? We are all aware that there is stupidity in EVERY field. Even as some of us have confronted our own union and pension reps there is a lack of concern for individuals and families within IWT complexes. As the president of this organization has stated many, many times let’s stick to providing each other with “facts” that can be put in front of those individuals who “do not understand how the real world works”. Facts can help move your argument forward.

The inference to those “not good at math” was to the trustees who approved and signed the deal; not to the teachers. I apologize it that is how you interpreted it.
