The goal of matching 45% of its purchased power with renewable electricity (in 2035) seems fairly average of what the typical grid user will likely get in 10 years.
The word "matching" is what carries the implications. They could be saying that during optimal weather conditions when solar/wind is flooding the grid and the prices are at the lowest, they will pay an additional to 45% of their purchased power, in order to "compensate" during periods of suboptimal weather when gas, goal and oil is the primary energy (which also mean when the power supply is low and prices are high).
