The government, by saying that there was a single zone, despite the electricity not actually working that way (because interconnectors don't have infinite capacity), were defying economics.

By breaking the country in to zones, where the electricity that's bought can actually reach the users they then apply the actual economics of the system properly, and encourage suppliers to build where the demand can be satisfied by them.

But in the past it made sense to have a single zone- prices were similar. So industry developed where possible. Now what you ask is that due to the ren generation, the pricing should change, so that industry that was formed long before current ren push needs to restructure/move to more advantageous locations because otherwise it'll use competitiveness. If you are fine with such development and it's consequences, you could ask for such reforms.

Situation is very similar in Germany - most industry is concentrated in the south while most productive wind in the north. In the past it didn't matter since prices were similar with coal. But now, since you can't magically create wind in low wind/unproductive areas, the options are either split zones and kill part of industry, which Germany doesn't want, or to keep a single zone and build expensive transmission like sudlink.
