Specifications include, but are not limited to: Providing Mesa’s Electric Utility with electric energy to the delivery points. Mesa is seeking a product that allows Mesa to contact the supplier the day before (or slightly prior to) dispatch in order to determine if it is more economical to dispatch this resource instead of purchasing power on the wholesale market typically called a “Daily Exercisable Physical Power Day-Ahead Call Option on Firm Energy”. Historically, this has been structured as an annual premium/capacity payment and then the dispatched energy price has been either i) a fixed heat rate multiplied by a daily index price for natural gas for example, “Platt’s Gas Daily under the heading “Daily Price Survey” Daily Midpoint, Other, SoCal”), or ii) a fixed energy price across the term. Mesa is seeking physical, delivered energy and NOT a financial hedge or other derivative.
