Tesla Powerwall powers New Brunswick home as part of pilot project

The company best known forbuildingelectric cars, has now started powering a New Brunswick home.

Stephen McNeil's home Fredericton Junction is the first to host a Tesla powerwall in the province.

The powerwallcame from thecompany'sdesigns for electric vehiclepower storage. It is a wall-mountedbattery unit designed to holdelectricity from alternative power sources, as well as the grid. It will power a structure during times ofoutages.

The unit ispart ofthepilot program,Reduce and Shift Demand Program that involves Tesla Energy, Ontario'sMPOWER Energy Solutions andNB Power.

"I was looking at one of my bills one day," said McNeil. "I noticed a discrepancy in it so I contacted NB Power and they fixed it right away and and that evening I received an email from NB Power asking if Iwanted to be part of a pilot program for the new Tesla Powerwall."

McNeil is the first andonly New Brunswicker so far to receive apowerwall unit. He charges it with solar energy from his 39 solarpanels, as well as energy from the grid. Stored energy can power a home for several hours.

"It all depends on the load I put on it," said McNeil. "Right now I have a fridge, the freezer. I have a living room circuit which has the TV and the modem. They say that depending on the load and what comes on at any given time, anywhere between 12 and 24 hours."

Captures energy

The large, sleek, wall-mounted batteriesaredesigned primarily to capture energy collected bysolar rays in order to power homes and businesses during nighttime or when the sunlight is obscured. It can also be used to collect energyfrom the grid during time periods whenelectricityis not in high demand and use it during peak hours, when electricity is in highdemand.Homeowners would see savings on their bills in areas where primetime pricingat higher rates is ineffectforelectricityconsumed during peak hours.

"They did a mock power outage and within two seconds the backup battery kicked in and was feeding into the circuits I selected," said McNeil.

"We are one of several utilities across Canada participating in national trial of 25 homes that willtest the technology requirements to install a battery system, allowing the household to store power," Marie-Andre Bolduc,spokespersonfor NB Power wrote in an email.

"From the utility's perspective, this trial is one part of the development of an integrated smart grid system thatwill allow NB Power to test the battery capability, by charging it during off peak times to reduce the demand on the provincial grid."

The pilot program will only see a single Teslapowerwallinstalled in New Brunswick.

"In New Brunswick, one customer, who is currently part of our net-metering program, has met the program criteria and has had this technology installed in their household for the duration of the trial," wrote Bolduc.

The MPOWER Energy Solutions websitecurrentlyhosts asign upfor the powerwall.

The pilot program will run for a year saidMcNeil.

"After that, they said I get to keep it, said McNeil. "And while it's rated to run tenyears without losing anycharge, but the Tesla guys say it will probably last for fifteen."
