•What is GoodCents® SELECT ?
• GoodCents® SELECT is a residential advanced energy management system that gives customers control over their energy purchases by allowing them to program their central heating and cooling system, electric water heater and their pool pump to automatically respond to varying prices.
– The “full cost” of responding to price changes is much more than the price difference.
• Customers must act in order to respond.• These actions require time and effort.
– Lowering the incremental “cost” of responding should increase the amount of price response.
– An in-home, customer-programmed, automated energy management system lowers this “cost” that customers must bear.

Why is GCS good for Gulf ?• Innovative Rate Offering (More
Choice)
• Operational Benefits (Peak Shaving and Valley Filling)
• Customer Satisfaction
• FPSC/FEECA Rules
GoodCents Select – Program Economics
• Significant Real-Time Demand Reduction!– Over 2 kW per subscriber per critical event 100 event-hours per year is O.K.
• Event durations of 1 to 3 hours
– These demand responses are exactly like quickly dispatchable capacity
• CTs or Hour-Ahead Spot Market Purchases• 80 MW of available critical peak demand response will
displace the need for an 80 MW bank of CTs or the need for 80 MW of hour ahead capacity purchases
GoodCents Select – Program Economics
• Load reshaping can be profit preserving– Moving consumption from higher to lower
priced periods reduces revenues and reduces costs but profits can be preserved
• Program facilitates the promotion of the most economically efficient electric end-use loads and technologies– Off peak end-uses of electricity become
relatively more economic – sales can increase
GoodCents Select – Program Evaluation

GoodCents® SELECT
The Primary Motivators
GoodCents® SELECT
When Do We Call a Summer Critical?
• If Gulf Power interruptible load has been called
• If the RTP price for an hour exceeds a certain threshold OR if the daily forecast dry bulb temperature at the Pensacola Regional Airport is 95 degrees Fahrenheit or above for that day, call critical based on consultation with System Control
• If there is an expectation of an annual Gulf Power peak demand for the day
When Do We Call a Winter Critical?
• If Gulf Power interruptible load has been called
• If the RTP price for an hour exceeds a certain threshold OR if the daily forecast dry bulb temperature at the Pensacola Regional Airport is 32 degrees Fahrenheit or below for that day, call critical at either hour beginning 0700 or hour beginning 0800 based on consultation with System Control
• If there is an expectation of an winter Gulf Power peak demand for the day
