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

Page 5: Smart Grid & Beyond

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 ‐

MS Hohm)– Outage status updates– Prepay

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.

Page 19: Smart Grid & Beyond

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.

Page 23: Smart Grid & Beyond

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

Page 24: Smart Grid & Beyond

Summary• Our Approach to Smart Grid

– Apply today’s technology to today’s business  environment

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

Page 40: Smart Grid & Beyond

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

Page 41: Smart Grid & Beyond

• 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.
