This one caught me out…..
To solve ‘duck curve,’ Missouri utility to pay bonus for west-facing solar panels.
In an effort to better align solar-energy production with peak demand, the electric utility in Columbia, Missouri has begun to pay higher rebates for new west-facing arrays than it will for those facing south.
Fantastically simple. Sure, not everyone has west facing roof space, but why not incentivize those that do and are thinking about adding solar?
The biggest problem with the duck curve is that evening ramp up. As the sun sets, the people go home and the solar output really drops off, the power companies have to fairly quickly ramp up megawatts of generation, sometimes even getting close to a gigawatt.
Thats tricky and expensive.
A west facing solar panel will put out more power at sunset than a north or south facing one (the usual direction).
To be clear, it will NEVER solve the duck curve. Only storage will, but it is a small step in reducing the steepness of that curve up the ducks neck.
