Towns that are negotiating their aggregations this fall are seeing their rates jump 40-60% and they're going to stay high for two years (though maybe market prices will also stay high).

Norwood Power and Light is likely setting their rates every 6 months and so it's likely that Norwood will see a greater jump this winter while seeing prices come back down as the energy market cools (assuming it does).

Norwood Power and Light isn't a for-profit company trying to milk you for profits. They're your town.

I'd also note that Norwood's electric rates are $0.1199/kWh which is pretty great right now. However, that might go up in January. If people are "see[ing] almost double the usual cost of [their] electric bills" in Norwood, they're either using more electricity or forgetting how much they usually pay.
