COMMUNICATIONS FOR THE SMART GRID

SMART GRID IMPLICATIONS FOR CABLE OPERATORS

Matt HaileTantalus4.6.2011


Smart Grid Overview How do we define the Smart Grid

– The application of technology to upgrade and improve the electricity grid

– Previously SG was Advanced Metering Infrastructure (AMI / smart meters), now first step is often Demand Management or Distribution Automation.

– Smart Grid uses technology and business models to improve control, efficiency, and reliability of the electricity grid.


Why do we need a Smart Grid?

• A smarter grid applies technologies, tools and techniques available now to bring knowledge to power

– Ensuring its reliability to degrees never before possible.– Maintaining its affordability.– Reinforcing our global competitiveness.– Fully accommodating renewable and traditional energy

sources.– Potentially reducing our carbon footprint.– Introducing advancements and efficiencies yet to be

envisioned.


Why is this happening?

• Hundreds of thousands of high-voltage transmission lines course throughout the United States, only 668 additional miles of interstate transmission have been built since 2000.

• As a result, system constraints worsen at a time when outages and power quality issues are estimated to cost American business more than $100 billion on average each year.

US DOE


Regulatory ActionsAct 129 - Pennsylvania— Act 129 directed that all electric distribution companies with at least

100,000 customers are to file an energy efficiency and conservation plan— Requires a 4.5 percent reduction (1,193 MW) in peak demand by May 31,

2013– The utility could be fined up to $20 million for failing to meet these reduction

targets.

Why is this important to businesses – beyond social implications

1. Think about the scale– # of endpoints on network

increasing– Interval data updates

2. Think about costs– A small change in peak

demand can lead to significant cost savings

3. Think about benefits– Programs typically target

3% - 6% reduction in energy; depends on specifics of program

Financial Implications

• Technology has evolved rapidly: - Smart Meters more sophisticated and reliable - Costs have decreased

• Many early adopters abandoning original AMR systems:- Features that were once uneconomic & unproven now cost-effective, reliable and practical

Trends and TransformationsDriving Change

• Business case justified• Costs reasonable• Benefits quantifiable• Skilled workers retiring• Conservation a

necessity• Co-opetition among

vendors

Typical Day• Utility forecasts how much energy it

expects to use on a given day• Purchases energy slightly in excess of

forecasted peak demand• Typical peaks morning & evening; more

costly to produce energy during these high-use periods

Peak Day• Energy consumption spike usually caused by

unexpected hot/cold temperatures• Appliances & HVAC forced to work harder• Two tough choices:

- Spot Market: purchase energy that is often 10x higher than retail; costs & greenhouse gas emissions rise- Shed Load: brownout; inconvenience customers

• Goal 1: flatten the peaks by moving some consumption to periods where energy is more abundant and cheaper to produce

• Goal 2: shed load on specific devices (air conditioners / pool pumps) rather than enacting full-scale brownouts

• Goal 3: signal customers when different price levels are in effect so they can better manage household usage and reduce costs

DR Scenario #1 Direct Load Control• Utility encounters critical peak• Load Shed command broadcast to

participating customers• Power cycled down or shut off on

registered appliances (HVAC, pool pumps, etc.)

• Action verified & recorded at utility; data integrated into billing report

• Customer can override event• Utility can stop shedding event or

normal operations resume after pre-set period

PEAK


Signaling• Smart Thermostats (IHD) installed

- Smart appliances (fridge, dish & clothes washer)

• Alert sent to participating customer which TOU level is in effect or if load shed imminent

• IHD alerts all customers or only those enrolled in a particular DR program

• Customer decides on the level of participation - full, partial or ignore

• Power cycled down or shut off on selected appliances (HVAC, pool pumps, etc.)

• Action verified & recorded at utility; data integrated into billing report

• Customer can override an event or change preferences / programs at any time via the IHD console

• Use Case #3: Wireless WAN– Endpoints (meters / homes) are far enough away

from each other that we need Sharkfin on each home to connect to the network --- LAN not enough range

• Use Case #4: Indoor Modem– Indoor Modem connected to outdoor meter via

Ethernet– One of the Ethernet ports on the indoor ONT or

for comfort and desire to save on energy bills. Dashboard controls can also be

accessed from any smart phone that can access the web.


Recognize the Players

• Municipal Electric vs. City• Cooperatives• Investor Owned Utility (IOU)


OpportunityHancock Telecom and Central Indiana Power


Know your CustomerKnow what Itches• Know the Industry

– Each utility’s vision, philosophy, plans and priorities – that’s what drives their SG solution (if any)

• Understand electric utility economics– Generation/Wholesale Power Cost is the primary driver – it’s

all about cost/resource avoidance.– Is selling less of something a good thing?– Focus is on reliability, power quality – non-revenue generating

objectives


High Level Utility Overview• Strengths

– Building, operating and managing highly complex electro-mechanical infrastructure

– Commitment to reliability and redundancy – failure is not an option (Cost is usually second to reliability)

– Cautious and methodical – electric service is essential to public safety

• Gaps– Building and managing high-volume endpoint communication

networks– IT prowess– Application integration– Managing continuous consumer interaction


What are the Opportunities?• Seek solutions – not simply connectivity

– Networks– Non-critical communications – the place to start

– Non-time critical– Most consumer level data

– Command and control networks– Critical – failure is not an option…period.– Hardest space to break in to…need to build trust

– IT support– Enterprise level solutions

– OSS/BSS– Time differentiated billing– Customer portals– Call centers


Perspectives• How far along are you in thinking about smart

grid?– Just starting to look into it– Have met with local electric utilities

• What do you see as the key challenges of working with utilities?– Reliability– Security concerns– Geographic coverage /

dissimilar footprints

– Regulatory issues

– Operating philosophies

– Each wants to own the network


What are the Challenges?

• Build Trust– Haven’t necessarily played together very nicely in the past.

– pole attachments– municipal broadband

• Understand what’s at stake for the utility (your customer) economically, operationally, politically etc…

• Rethink customer care. A utility is not a customer. It’s a partner. Your highest priority partner. Often when their service doesn’t work, yours doesn’t either.


MSO’s and the Smart Grid

• Leverage the strengths of your organization to enable comprehensive end to end solutions for utilities

– Utility requires reliable, secure and low latency network– Speeds deployment by using an existing access infrastructure– Leverages technical skills of communications provider staff

• Communication service providers leverage their core asset – the network – as well as IT capabilities to provide utilities with the communications fabric over which the smart grid can be deployed

– Expands service revenue streams– Justifies deeper fiber deployment to electric sub-stations, wireless

base stations and perhaps all the way to the home


Develop Solutions

Recognize Cultural Differences and Develop a Strategy for SG


Which Utilities Make Good Targets

• Some utilities are more likely than others to cooperate

– Focus on utilities that do not produce their own power - those that buy all their power are more incented to implement Smart Grid

– The more territory overlap the better – Utilities with small IT and telecom staffs are more likely to be

willing to work with communications service providers


The Future is NowAdaptable communications technology that meets the broad set of requirements utilities face today and in the years to come.

Edison vs. Bell• If Alexander Graham Bell were somehow transported

to the 21st century, he would not begin to recognize the components of modern telephony – cell phones, texting, cell towers, PDAs, etc. –

• Thomas Edison, one of the grid’s key early architects, would be totally familiar with the grid!


Smart Grid Capital

• Smart grid is drawing capital investments

– RUS-Investing hundreds of millions in advanced metering in rural areas; client cooperatives cover 42% of US distribution network

– ARRA-$3.4 billion in funding for Smart Grid projects was awarded by the Department of Energy in 2009

– Tantalus funding / finance facility– Significant private capital is flowing in to Smart Grid

– Over $4 billion complements ARRA funded projects
