From the article:

The glowing phone booth, it turns out, is actually a giant battery. Built by Toronto-based startup Civic Grid on behalf of The Nourish and Develop Foundation (TNDF), it helps power the neighbouring food bank for cheap while providing residents with a mini town square to gather and recharge. For Civic Grid, the pilot project is a demonstration of a new kind of community infrastructure.

“This square provides … lighting, shelter, seating, [and] an open courtyard to be an extension and to strengthen the TNDF’s existing programming,” Civic Grid founder and CEO Max Fine told BetaKit in an interview on Thursday. “Having these spaces within these communities, big or small, I think, are really essential as we electrify our systems and we go through this energy transition.”

The courtyard’s 60 kWh energy system charges during the cheap, off-peak night hours, then powers the TNDF’s two buildings for six hours the following day. That keeps its fridges and community kitchen running at less cost, while also providing insurance if the power goes out.

Fine said a battery like this shows how important energy access is for people to participate in society. Already, multiple people are charging their phones in the courtyard in the morning, and it has helped an electric wheelchair user get moving when they ran out of juice. This philosophy is also reflected in the design, with the stone base meant to evoke a community water well.
