Tending the Grid Power Balancing Operator Leader Kresta Davis-Butts leads a team of people who work around the clock to match electricity production with our customers’ energy needs.

Balancing Electricity Supply and Demand is a 24/7 Job Moving electricity from where energy sources with the ups and downs Every time someone plugs in a cell it’s generated to your home or of customer demand. Imagine a large phone charger, starts an irrigation pump business requires a complex water tank with thousands of spigots or switches off a light, the demand balancing act that goes on constantly being turned on and off. on the grid — called system load — 24 hours a day, every day. Coming into the tank are hundreds of fluctuates. Often, it happens behind the hoses keeping the tank full.

The FCA is filed each year on or near March 15 and only affects residential and small general service customers.

3 Price Change (continued from page 3) PCA The PCA is an annual filing that updates customer prices to reflect the current variable costs and benefits of operating the electric system. Neither Idaho Power nor its shareholders receive any financial return on the PCA; money collected from the surcharge can be used only to pay power-supply expenses. • It forecasts anticipated fuel costs, costs to purchase power and customer benefits from sales of surplus energy for the coming April through March. • It “trues up” last year’s forecasted costs with the costs actually incurred Coming from Mike the previous April through March. Prices are established by adding the forecast and the true-up to align actual collection with actual costs. Customers also benefit when we sell surplus energy to the wholesale market when we have more than we need to serve customers. The money from those sales is deducted from our power-supply costs and reduces the prices customers pay through the PCA. The PCA is filed each year on or around April 15 and applies to all customers.
