Why is Smart Grid Needed Now?
Growth of renewables and distributed generation
Dynamics that could have a huge effect on a utility's ability to deliver
reliable power at a reasonable price
Distribution systems are inefficient –
Huge amounts of energy are wasted in line losses and an inefficient
system (5%)
Aging infrastructure that will impact the reliability of power as well as
inevitable rising costs
Generation shortfalls as demand growth well exceeds new generation
The need for infrastructure to support dispatchable demand response
What Does Smart Grid Mean?
Distribution
Management
Enterprise
Not
Silo Systems
Paradigm shift:
Data and
Communications
Maximizing
Renewables
Utility distribution systems have been operated as static “as built”
systems
With the growth of dynamic generation sources and the needs of the Smart
Grid the distribution system will need to be dynamically managed.
Dynamically controlling a complex distribution system will require new tools
and systems.
Utilities have generally deployed silo systems
Smart Grid is about an enterprise platform. All departments sharing data and
analytics. Actionable intelligence needs to be integrated between IT
systems and within the business processes.
Need higher speed enterprise communications and Smart Grid
opens Pandora’s Box of Data
Huge quantities of otherwise untapped data will be available. Up till now
utilities focused on SCADA data. The ability to collect, store and provide
data independent analytics will be required.
System designed to address dynamic renewable generation
Minimize costs and waste to allow for renewables

Analysis

Reduce energy and carbon by precise dynamic voltage control

Many studies have shown a 1% drop in voltage results in a close .8%
drop in energy demand

Reduce losses (I2R) due to unbalanced feeders (3 phase) and circuits

Reduce carbon, energy and costs by integrating load control functions
(voltage, DR, DG, etc.) into a single efficient solution

Reduce maintenance and capital costs, improve reliability, improve
system capacity

Supports CBM, dynamic rating, loss of life and replacement programs

System Optimization
Products that maximize the efficiency of the electricity flow from the utility to the customer.
Volt/Var Control
Phase Load Balancing
Power factor optimization through
integrated control of capacitor
banks
Identification of load imbalance
sections in feeders and
recommendations to remedy
imbalances for loading conditions
and seasons
Dynamic Voltage Optimization
Voltage optimization through
control of the substation Load Tap
Changer Controllers based on
real-time voltage measurements
throughout the feeder
Benefits
• Immediate savings by all rate payers
• Deferred spend on generation through the lowering of overall power requirements by up to 5%
• Reduced carbon emissions through the efficiency based reduction of overall power generation
SmartGridCityTM – Boulder, Colorado
Collaborating to Build the Next Generation Utility
“The fundamental component for making the smart grid work will be a robust and dynamic communications network;
providing the utility the ability for real-time, two-way communications throughout the grid and enabling interaction with
each component from fuel source to end use” (Xcel Smart Grid White Paper)

Smart Grid Operational Impact - Xcel
 Using the CURRENT portfolio, Xcel has found numerous issues on its grid
• Customers back-feeding the grid
• Broken and loose neutrals
• Transformer failures
 Xcel is operationally changing their behavior
• CEO of Xcel and President of PSCO pushed mobile version to field crews
• Field crews liked it so much they have asked when more feeders will have this capability
 Mental and fiscal shift from reactionary to preventative O&M
• Area manager shifting budget from trouble shooting to preventative

Conclusion
True Smart grid projects can be proposed for stimulus
money. No need to dust off old projects.
Smart Grid benefits both the consumer and utility
• Consumers get lower cost, cleaner more reliable energy
• Utilities get reduced operating costs, lower generation costs,
and a more reliable and efficient distribution system.
