"It was one of the easiest things I've ever done". "I just set the
thermostat and let it save me money. The biggest change is that
it makes you more aware of your habits and usage of
electricity."

The present situation
 Even though American consumers routinely
encounter time-of-use pricing in daily life,
from parking a car to buying an airline ticket,
they do not encounter it when buying
electricity
 About one in four residential customers have
smart meters but only two in one hundred
are on a time-of-use rate
 One of the barriers is a perception that
customers won’t respond

An American tour of the future
Arizona
 Over two decades, Arizona Public Service has enrolled 51% of its customers
on a voluntary TOU rate and the Salt River Project has enrolled about 30%
of its customers on a voluntary TOU rate
 In both cases, the TOU rate appeals to large consumers who avoid the
upper tier of an inclining block rate by going with TOU
California
 PG&E has enrolled 80,000 customers on CPP
 SDG&E is offering PTR on an opt-out basis to nearly two million customers
 SCE is offering PTR on an opt-in basis to millions of customers
Illinois
 Both the investor-owned utilities, ComEd and Ameren, have enrolled about
25,000 customers on RTP in Illinois
 A new state law calls for opt-in PTR to be offered statewide
SGCC 2013
27
The Brattle Group
An American tour (concluded)
Oklahoma
 OG&E has begun rolling out VPP and hopes to sign up 20% of its
customers over the next 2 years
 By so doing, it hopes to avoid building a medium-sized power plant
The Mid-Atlantic Region
 BGE and PHI will be offering PTR to 2 million customers over the next
few years in Delaware, Maryland and the District of Columbia
 PJM is allowing price-responsive demand to be bid into its multi-state
markets, as AMI and dynamic pricing are rolled out in its footprint of 51
million customers
SGCC 2013
28
The Brattle Group
An international tour of the future
Canada (Ontario)
 3.9 million (81%) residential and small business customers are on TOU rates
under a regulated retail pricing plan (March 2012)
 All customers have the option of switching over to retail providers
China
 Beijing: 62% of the population was on TOU rates by the end of 2003
 Hebei: 40,000 customers (about half of all sales) are on TOU rates
Additionally, Hebei has instituted a mild CPP rate
 Jiangsu: Voluntary residential TOU since 2003
 Shanghai: TOU rate with a 4.5-to-1 peak to off-peak price ratio
France
 Électricité de France has offered residential customers CPP across France
through the tempo tariff since 1996
 About half a million customers have enrolled into the rate
SGCC 2013
29
The Brattle Group
International tour (concluded)
Ireland
 The Commission for Energy Regulation is currently assessing the pros
and cons of mandating TOU tariffs
 Stakeholder engagement will follow in 2013
Italy
 Currently, 28.8 million customers are on a TOU program
 18.8 million are residential customers
 ~91% of these residential customers have defaulted to the TOU
tariff
United Kingdom
 Consumer Focus found ~75% of consumers on TOU tariff are
satisfied
 Most popular TOU tariff is the Economy 7 tariff
SGCC 2013

The Brattle Group
Creating the Future
 Opt-in
 Makes sense but only if the dynamic pricing rate is net of the
hedging premium in flat rates and if dynamic pricing rates are
simple and easy for customers to understand
 The rates should offer customers significant savings potential and
also be offered in a way that appeals to other customer needs
besides just saving money.
 Opt-out
 Best to offer it with full bill protection for the first year and to
phase this out over the next two to three years
 An alternative is to offer two-part rates
 Another alternative is to offer peak-time rebates
SGCC 2013
31
The Brattle Group
Opt-in
Opt-in participation rates tend to be quite low
 The rate is 1% in the US for time-varying rates and 1% of that
1% for dynamic pricing rates
However, if the hedging premium that is embedded in
flat rates is removed from the dynamic pricing rate,
making it less expensive than the flat rate, higher
participation rates can be expected
 The Arizona example cited earlier makes the point: TOU rates
have been selected by 51% of the customers for one utility
and by 29% for another
SGCC 2013
32
The Brattle Group
Opt-out
If dynamic pricing is offered on an opt-out basis,
societal benefits will be maximized but several people
may see higher bills
 They could be allowed to opt-out
 Selective opting out by the most expensive to serve customers
could result in high rates for everybody
 Better to ensure adequate protections for all customers in the
first few years
SGCC 2013
33
The Brattle Group
To manage the politics, the best option may
be to put forward a hybrid offering
 Mandatory for customers above a certain
size
 Optional for low income consumers
 Opt-out for everyone else
