“Smart Grid” is more than Smart Metering
Where IC Vendors Can Help
• Technical Requirements of the Grid
– Low Cost Sensing Solutions need to be deployed across the network
– These solutions must be capable of harvesting “real” information from raw
data
– This real information must be turned into “actionable intelligence” (i.e.,
recommendations for control, dispatch and/or network operations)
– This “actionable intelligence” must be integrated into the utility’s operational
systems
– Some of these operational systems must be allowed to become background,
automated, control applications
– Any automated control applications must be able to control end points with
validated results
• Required Smart Grid Building Blocks
– Distributed intelligent sensing and control nodes (grid sensors)
– TWO-way, open, high speed, low latency communications
– Edge and back office analytics software

Business Models and Standards
• There are HUNDREDS of projects across the country – all “testing
out” various business models and technologies to support the Smart
Grid movement

• Ultimately, the power utilities must see value (i.e., ROI) in putting in
the required capital
• IP, Homeplug, Zigbee, 802.11 are standards widely accepted in Smart
Grid pilots today; IEEE 1547.4 gaining attention
• DNP3 and IEC61850 are used for distribution and substation
equipment communications
• World needs a Smart Grid that can utilize these standards and allow
for true OPEN integration (defined as allowing a provider to
independently build solutions that can seemlessly connect to the
network once granted security and permission by the utility) of multivendor ecosystems.
The Smart City Project in Boulder, CO
• $100M Project (85% paid by the utility)
• Driven by the “Smart Grid Consortium”
(formed Dec. 2007)
• Xcel Energy (utility)
• Current Group (Smart GridTM
hardware and software)
• Accenture (project management)
• GridPoint (IT platform for
utilities)
• OSIsoft (data collection and
management)
• Smart Synch (metering)
• Schweitzer Engineering
Laboratories (protection,
monitoring & control across
transmission lines
• Ventyz (work management
software)
• Estimated June completion
• Enel S.p.A. of Italy completed the first
Smart Grid city experiment in 2005 - the
Telegestore project.
• Proven to deliver annual savings of
500 million € at a project cost of 2.1
billion €.
