Yea, price capping is as much communism as having public healthcare and when the price of electricity was capped it lowered the prices massively.
What was going on was the local power companies made deals with other countries and basically acted as middle men for reselling that power for a massive markup. Our government made a mandatory power plan that forces power companies to produce electricity locally for local supply at a fixed price and that pretty much fixed that. Those companies couldn’t sell power at a massive markup anymore because everyone would just switch to the government power plan then.
