Municipal buildings to draw on solar power

City council is expected to approve an ambitious plan next week that

will see up to 20 government buildings around Toronto get their heat

from a new kind of energy provider: the solar utility.

Rather than pay the high upfront costs for its own solar energy systems,

the city plans to select a company that will install, own and operate

the solar thermal equipment on city buildings. In return, the city will

sign a long-term contract - lasting 10 years or longer - agreeing to pay

a fixed price for the renewable heat the systems produce at a rate

that's equal to or less than the existing rate for natural gas.

But unlike natural gas, solar heat produces no emissions and isn't

subject to price volatility.

"There's no downside to it," said Bruce Bowes, the city's chief

operating officer and a forceful backer of the proposal. "It gives us

more stable pricing ... reduces CO2 emissions, and it helps the city

appear as one of the better renewable energy capitals in the country."

The model is no different than a gas utility that agrees to pay the

capital cost of running a pipe into your home in exchange for your

purchase of natural gas and its delivery. Over the length of a contract,

the upfront cost to the utility is more than offset by the customer's

long-term energy purchases.

Solar panels, depending on the type, can either generate electricity or

produce heat. Solar photovoltaic systems are designed to produce power,

while solar thermal systems - the kind recommended in the city plan -

describe technologies that use the sun's energy to heat buildings and

water.

The proposal goes before council on Monday, coincidentally on the

opening day of the Canadian Solar Industries Association's annual trade

conference in Toronto.

Once approved, a request for proposals will be issued, inviting

companies in the area to bid for the business.

"It should be rubber-stamped," said Keith Stewart, a climate-change

analyst with environmental group WWF Canada.

The buildings that do initially get equipped won't be completely free of

using natural gas (or electricity) for heating, as the sun doesn't shine

on cloudy days and at night. But the solar energy produced over a year

typically reduces the need for fossil fuels by more than a third.

Toronto already has some experience with solar thermal heating. The city

has installed systems to heat pool water at three recreation centres -

Scarborough Centennial, Agincourt and Jimmie Simpson. Two fire stations

in the city also get their hot water from solar panels. But unlike the

solar utility approach, the city owns those systems.

Louis Fournier, vice-president of sales for Toronto-based Mondial Energy

Inc., one of the companies likely to bid for the city's business, said

municipalities don't store and deliver their own natural gas or generate

their own electricity, so it makes sense that they don't build and own

their own solar energy systems.

"This fits with their long-term plan of using more renewable energy

without putting a burden on taxpayers," said Fournier.

Mondial began promoting itself as a solar utility about three years ago.

Since then, it has signed long-term contracts to supply a 170-unit

community housing site on Queen St. E., a 205-resident seniors building

near Danforth and Coxwell Avenues, and a 64-suite residence at Main St.

and Kingston Rd.

All systems can be monitored in real-time over the Internet, making it

easy for any resident or building operator to verify performance, energy

savings and the amount of greenhouse gases being displaced.

Bowes said 20 buildings are likely just the start for the city. "If this

is quite successful, there's no reason to not continue," he said.

"There's no reason to limit it to 20 buildings."
