One Utility's Approach
• Apply today’s technology to today’s business issues
– Increasing generation costs– Increasing need for reliable electricity– Increased consumer desire to manage energy costs
– Increased interest in conservation
Strategic Plan
We shall be among the industry leaders by maintaining a Technology Plan that provides for the
aggressive use of proven technology to enhance reliability and member service while decreasing local
operating costs.
– At least three technology advances will be made each year, supported
by a business plan, which will have a direct positive impact on the
membership.
Our
Strategic Plan• “Technology Plan”
– Cross departmental 5 year technology plan• Not “Smart Grid”
plan
– Focused on key technologies to drive desired business outcomes.
• “At least three technology advances will be made each year,
supported by a business plan, which will have a direct positive
impact on the membership”– AMI– SCADA– Web presentment (Google ‐

Comments Received
• First, kudos for taking the lead partnering with Google to make this power
data much more actionable.
• GPM immediately indicated what I had long suspected, that I have
a very
high (>1kWh) "always on" load, probably my furnace fan and whole
house
air exchanger.
Already running a few tests to verify.• That sounds great and what a terrific thing you did by giving us
the data
early! Kinda
interesting to watch the power usage go down in relation to
the solar data we're collecting. Thank you so much.
• As you might suspect it leaves a lot to be desired for a guy like me, but it's a
start.
I like the data connection, and the ability to download to excel.
Information• What we are doing now
– Back of bill (daily)– Web access to consumption information (Google)– Use hourly meter data on bill questions
• What we plan to do in the future– Multiple options for web access
(Google/Microsoft/Others)– Additional information on bill

Impossible?
• "Alice laughed: "There's no use trying," she said; "one can't believe impossible things."
• "I daresay you haven't had much practice," said the Queen. "When I was younger, I
always did it for half an hour a day. Why, sometimes I've believed as many as six
impossible things before breakfast.“
• Alice in Wonderland.
Keys to Success• Company wide technology plan
– Focused on fundamental business issues
• Partnerships– We don’t have internal resources to do everything– We’ve relied upon other cooperatives and technology
partners
• Communication without overselling– Let members know what your doing– Don’t oversell the impact
Summary• Our Approach to Smart Grid
– Apply today’s technology to today’s business environment
• Smart Grid Member Impact– What does smart grid provide our members?

DRU Key Features• Intelligent Comfort
– Monitor average on/off times to provide profiles of individual devices
– Allow load for a percentage of average on time
• Intelligent Outage Recovery– Power Interrupt feature Continues load shed after an outage
• Cold Load Pick‐up– Prevents demand spikes as devices are brought back on‐line.
• Autonomous Load Control– Provides 2 Under Frequency (UF) and 2 Under Voltage (UV) set points.
• Each UV/UF set point contains trip and clear thresholds
• Utility can control set points per substation
• DRU’s
can be programmed to react as needed ‐> e.g. shut‐off devices, simply
monitor
• System Diagnostics– Tamper Detection
– Hardware & Firmware Diagnostics
Demand Response – Strategy Definitions
• Define your strategies and delivery points• Examples:
– SCRAM• 100% Everything until stop command
– Water Heaters• 20% Water heaters
– LC Level 1• 20% A/C• 50% Water heaters• 100% Irrigation
– LC Level 2• 50% A/C• 80% Water heaters• 100% Irrigation
• As a “front end”
to existing Outage Management Systems
• To get a fast data response
from specific TWACS transponders.– Specific TWACS transponders can be:
• Individual meter(s).
• Random selections below specific protective devices
• Entire Feeders
• Quickly identify the extent of an outage– 30‐40% of individual calls have power at meter (Internal Trouble)
– Targeted “Pings”
can “traverse”
the distribution network to identify which devices
are without power
• Verify
that all meters
affected by an outage have been restored– Especially beneficial in large storm restorations.
– Crews complete an area before they move on.• Clear “nested outages”
while crew is still on site.
