Is our Crown-owned electricity market regulator scared of private solar proliferation?

This is odd:

At present, 67,000 homes generate electricity from solar panels on their roof – a tiny percentage of the two million homes connected to the national grid.

But those 67,000 are a forceful minority, who argue they are producing clean energy from sunshine.

However, Electricity Authority chief executive Carl Hansen told Nine to Noon that going solar could hurt people in the pocket while doing nothing for the environment.

“It is scarce money that people are spending on installing their own renewable generation that is already in their system,” he said. “The environment is not any better off.”

Unless all of the electricity generated in New Zealand is from renewables, and unless the dams are going to never run low, I think that’s a bit of a rich statement.  

Mr Hansen said, since over 80 percent of New Zealand’s electricity was now renewable, there was little environmental gain from going solar.

It was also a costly way to go, he said, because solar electricity was expensive to generate.

“You are having solar generation come in, the cost of it is about $200 a megawatt hour,” he said.

“But grid-supplied generation from wind or geothermal, which is equally renewable, is about $80 a megawatt hour, so the current price structure is encouraging people to go and buy expensive stuff.”

I’m not aware of anyone getting into solar because it costs them more than taking electricity off the grid. Hansen’s argument is that the big boys are more efficient, but he doesn’t line that up against single case studies.

Solar energy is essentially free in perpetuity with the only problem being that you have to pay off your kit over time.  You pay a lot in advance.  But with more efficient cells, more efficient micro-inverters, more efficient and cheaper storage, the numbers continue to tumble in the right direction.

I suspect what the Electricity Authority is really concerned about is that a larger private solar commitment is going to undermine the long-term investments that our generators have made, perhaps causing them to have to up their prices.

Just arguing to not use solar because you’re swapping renewable for renewable is not what most people buy solar for.  They buy it because, over a period of time, it starts saving them money.
