Getting Paid To Soak Up California Solar

On the trading floor of Arizona Public Service, all eyes are trained on the price of energy in California, especially when customer demand is low, but solar panels are producing the most power.

The people who run our electricity grids are trying to figure out what to do with solar and wind power that is generated when no one needs it. Take California – there’s enough solar there now to serve more than three million homes. But during the day, especially in the spring, demand is low and generation is high. So, that clean power has to be sent elsewhere. Right now, its going across state lines to Arizona. Continue Reading →

As we talk about the future of renewable energy, there's one aspect that should be at the forefront of the conversation: storage. We've already figured out how to capture wind and solar energy, but it's equally important to figure out the best way to store this energy and use it when it's needed. Continue Reading →
