One town, three settlements, one distributor
New Tecumseth covers Alliston, Beeton and Tottenham, and Alectra Utilities is the local distribution company for the town. That means the utility side of a solar project looks the same whichever of the three you live in: the same distributor, the same connection process and the same residential rate structure. The municipal side is where the differences show up, because heritage designation in this town is concentrated in Beeton and the character of the housing varies between an older village core and newer subdivision development.
The physical resource is essentially flat across the municipality. Modelled yield here is 1,157 kWh per installed kW per year, so a 6 kW array corresponds to roughly 6,940 kWh annually, an 8 kW array to about 9,260 kWh, and a 10 kW array to around 11,570 kWh. Those are averages over many years rather than a promise about any particular twelve months.
Because Alectra serves a large footprint of Ontario municipalities rather than just this town, its residential processes and rate schedules are standardised across that whole territory. The upside is that installers working anywhere in the Alectra area already know the paperwork. The thing to watch is that generic advice written for a big-city Alectra customer will not have anything to say about New Tecumseth's own building department or its heritage rules, which are entirely municipal.
Weekdays are priced, weekends are not
Alectra's residential time-of-use structure charges off-peak at 9.8 cents/kWh from 7pm to 7am on weekdays plus all weekend, a mid-peak band, and on-peak at 20.3 cents/kWh, with the peak windows swapping position between the summer and winter seasons. The part homeowners overlook is the weekend. Saturday and Sunday sit entirely at the off-peak rate all day, which means the electricity your array generates on a bright Saturday afternoon is displacing the cheapest power you buy all week.
That has a real design consequence. Roughly two sevenths of your annual production lands on days when self-consumption is worth the least it can be, so a larger share of weekend generation flows out as export credit rather than as avoided purchase. Since Ontario credits exports kWh-for-kWh at the retail rate, that is not a loss, but it does mean strategies that depend on consuming your own output at a high price, load shifting, battery cycling, deliberately running heavy appliances at midday, do their work on the five weekdays and largely idle on the other two.
Weekdays are the mirror image. Between 7am and 7pm on a weekday your household is exposed to the mid-peak and on-peak prices, and that is the window a rooftop array covers best. If somebody is home during the day, if you work from home, or if you can move a dryer or an EV charge into daylight hours on a weekday, that is where the difference between 9.8 cents/kWh and 20.3 cents/kWh is doing the most for you.
What net metering through Alectra involves
Alectra Utilities is where a New Tecumseth homeowner applies for net metering to connect a rooftop system. Ontario's net metering framework is provincial, so the terms do not vary by distributor: what you export is credited kWh-for-kWh at the retail rate against future bills, unused credits carry forward for up to 12 months, and there is no cash payment for a net annual excess.
The consequence of that carry-forward rule is a sizing ceiling. Once a system generates more over a year than the household consumes, the extra credits expire unused rather than converting to money, so an array sized well beyond your annual kWh total is buying you nothing. Twelve months of your own bills is the input that decides the right size, and any installer who has not asked for them is guessing.
System size also determines which connection path you are on. As of May 1, 2026 the Ontario Energy Board raised the simplified micro-embedded generation threshold from 10 kW to 12 kW, so a band of larger residential systems now qualifies for the streamlined process. Confirm with your installer which side of that line your proposed system falls on, since it affects the paperwork rather than the equipment.
What the local housing mix means for an install
70.8% of the town's dwellings are single-detached houses, giving most homeowners here an independently owned roof and full authority over what goes on it. Only 0.5% of dwellings are high-rise apartments, so a condo corporation is rarely the decision maker in this municipality, and 8.7% are low-rise apartments where a landlord would be.
The shared-wall share is where the design work gets interesting. 9.1% of dwellings are row houses and 7% are semi-detached, and both involve a roof line that continues into a neighbour's property. In practice that means less usable area than the roof appears to offer, because fire access pathways and setbacks from the party wall have to be respected, and it means a conversation with the adjoining owner if any part of the racking, conduit run or scaffolding crosses the line during installation.
The Beeton district uses a three-stream review
Ontario does not have US-style homeowners' associations, so there is no private body that can object to your panels on taste grounds. Heritage designation is the real overlay in New Tecumseth, and it is concentrated in Beeton. The Beeton Heritage Conservation District covers 53 identified properties along Main Street West and East, Centre Street North and Prospect Street.
What makes this district easier to deal with than most is that the town sorts alterations into three streams rather than treating every change the same way: some work needs no permit at all, some gets streamlined staff approval, and some goes to full Council approval, depending on what is proposed. Where a solar array lands in that ladder depends heavily on visibility and placement, which is a strong argument for asking heritage staff about a specific layout early, when moving panels from a front plane to a rear one is still a free change on a drawing.
The town publishes no solar-specific permit guidance
We have no verified New Tecumseth permit guidance specific to solar, and rather than infer a process from what neighbouring municipalities do, the honest answer is that you should confirm the requirements directly with the town's building department before you commit to an installation date. Ask two questions: whether a building permit is required for a roof-mounted array on your property, and what the department wants in the submission.
One thing holds regardless of the municipal answer: electrical work associated with a solar installation falls under the Electrical Safety Authority and carries its own permit and inspection, separate from anything the municipality requires. So plan on two approval tracks, not one. And be sceptical of any specific turnaround figure an installer quotes you for this town, since we found nothing published by New Tecumseth itself that would support one. The building department is the only reliable source for how long your file will actually take.
Rebates, loans and the current federal position
Ontario runs the Home Renovation Savings Program, which since its January 2025 launch has been the province's flagship residential energy programme and is now in an expanded 2026-27 program year covering April 1, 2026 to March 31, 2027. For solar it offers combined rebates of up to $10,000 when panels are paired with battery storage, which is the pairing the program is built around rather than an add-on to a standalone array.
Read the fine print on configuration before you design the system. Homeowners who take the HRSP solar incentive are generally directed to a load-displacement setup rather than full net metering, so you are effectively choosing between two different system concepts, not stacking a rebate on top of the export credits described above. Get your installer to price both against your actual consumption profile and confirm the current program rules, because they have changed before.
On the federal side there is less on offer than there was a year ago. The Canada Greener Homes Loan, which lent up to $40,000 interest-free, stopped taking new applications on October 2, 2025 and is only funding files already approved. The Canada Greener Homes Affordability Program took over in September 2025, delivering no-cost retrofits through participating provinces, which do not currently include Ontario, to low- and median-income households, with solar federally eligible but each province choosing its own technology list. Nothing at the federal level plays the role the American residential tax credit plays south of the border. Municipal or utility financing such as local improvement charges surfaces periodically and is worth asking about, but it is not a standing programme you can plan around.
