Reply #3: Your understand of wholesale power is flawed.

[Statistical]

Renewables & nuclear have high capital cost and low operating costs. A windfarm will always sell 100% of its power to the grid. Always. There will never be a single second when they won't. Say a windfarm has a break even cost of 6 cents per kwh. At a particular point in time the highest price in wholesale auction is only 1.2 cents.

Even if a winfarm has to sell power at 1.2 cents per kWh (operating at a loss) it is better than not selling the power (0.0 cents). As a result the bill is meaningless. If is a feel good statement that doesn't materially affect the way business is done.

The bill doesn't set any minimum price point for renewable energy simply that it must be accepted. It will be decades before renewable energy is more than a tiny fraction of China energy demands.
