Why Bryan Adams's P.E.I. concert was a step forward for solar power

When Bryan Adams opened his North American tour on P.E.I. on Aug. 31, people behind the scenes were attempting another first that he didn't know about.

The concert was being held in Summerside, and the small city's electrical utility was trying to make the concert the first evening concert in North America to be entirely solar-powered.

BluWave-ai,the company whose software powers Summerside's smart grid,came up with the idea.

The plan involved adjustments to the grid that required the city's permission and Summerside's director of economic developmentsaid the city jumped at the opportunity.

"To showcase our capabilities as a leading North American municipality, we decided to deliver a 100-per-centgreen solar energy concert experience at our arena," Mike Thususka told CBC News.

The city has a large solar farm adjacent to Credit Union Place, the arena where the concert was being held. Since the show was at night, that meant all systemswould have to run off battery power from energy that had been collected during the day.

Devashish Paul, the CEO of BluWave-ai, saidthis requirement made the opportunity stand out as a potential North American first.

"There are some venues with solar power, but not with battery storage," he said.

2 big worries

The success of the experiment was by no means a sure thing.There were two key unknowns.

The company could make estimates, but it didn't really know how much energy it would take to power thesound, lights, and even air conditioning for the huge space.

The battery has a total capacity of 890 kWh, but is also limited in how quickly that energy can be discharged. At maximum output, as the company explains, the battery can power almost 1,000 100-watt lightbulbs, and keep them going for three hours.

And there was the second concern.

"What's Mother Nature going to give on that day? Because what Mother Nature gives and Bryan Adams uses kind of has to match up," said Paul.

"It was going to be a partially cloudy, partially sunny day, and it was a bit fickle in terms of cloud coverage. So basically we felt like there was a chance that it would all work out, but we didn't really know."

As thingsturned out, it wasclose, but at the end of the show, there was still a little juice in the battery.

Superbowl next?

With this test proving the technology works, Paul said BluWave-ai will be looking for other opportunities to use it.

The potential is significant. Paul noted that the halftime show at the NFL's Super Bowl is run off a diesel generator on the sidelines, because the production company is concerned about how robust the stadium's electrical systems are.

That's a much larger scale, but what happened at Adams's Summerside concert could work for the Super Bowl halftime show as well, said Paul.

"Just charge up these batteries and truck them in, just like you'd truck in diesel, and you can run the Super Bowl halftime show off daytime solar with these batteries," he said.

Using electric trucks to transport those batteries could make for a 100-per-cent clean show, Paul added.

"We can decarbonize and still run our shows."
