A mix of smart
technologies, customer engagement, and demand response will help bring
electricity production and consumption into the precise alignment that the grid
requires to function properly. While innovative energy storage approaches may
play a future role in managing this exacting dance between power supply and
demand, other more proven and more cost-effective options will be required in
the near term.
The impressive ability
of demand response (DR) to reliably stabilize electric systems under pressure
has been on full display in the past year: DR helped keep the lights on during
hours of record-breaking summer power demand in New York last July, and also
during hours of record-breaking winter power demand in Texas just this month.
It appears that nimble
DR mechanisms (e.g. dynamic pricing and real-time customer engagement) will
become increasingly valuable assets for utilities as a low-cost strategy to
manage not just weather-driven peaks, but also the day-to-day patterns
associated with a cleaner and smarter electric grid.
1. Energy efficiency
policies worldwide.
More than half of US
states have now officially enacted quantitative energy efficiency targets, and
around 30 states offer concrete incentives to utilities that drive reductions
in energy demand. Yet even more states have instituted a framework for severing
the tie between utility energy sales and revenue, thereby removing the
disincentive for utilities to help electric and gas customers lower their
bills. Mississippi and Louisiana are the latest players to join the
energy efficiency policy landscape.
Across the pond,
European member states recently formalized their action plans to achieve an
EU-wide 20 percent reduction in energy consumption by 2020, as part of a
sweeping Energy Efficiency Directive.
And in Asia — where
it’s forecasted that more than half of
annual global energy consumption will be consumed with a few decades by 2035 —
several countries are becoming more aggressive with efficiency policies. Japan,
Singapore, China, and many developing nations in the region are finding
efficiency to be one of thecheapest and
cleanest energy resources at their disposal.
2. Natural gas and
renewable energy keep chipping away at coal
America’s energy
portfolio is changing. Natural gas — along with clean power — is persisting in
chipping away at coal’s segment of the US energy generation mix.
Much of this shift is
due to the expansion of oil and natural gas production here at home. Domestic
natural gas production is projected to grow 56 percent between
2012 and 2040. And by 2040 — if not earlier — natural gas will displace coal
as the primary fuel for US electricity generation. The shift is already under
way: in November, the Tennessee Valley Authority — located in one of the top
coal-burning states — announced its
plans to shutter eight coal plants representing 3,300 megawatts of capacity.
At the same time, the
share of renewable energy in the US generation mix continues to grow rapidly.
3. Innovative
utilities are exploring ways to thrive in a distributed-generation world
How should a bakery
respond when, each year, more and more of its customers want to start baking
their own cookies?
Electric utilities
will confront a similar situation in 2014, as tens of thousands of additional
homes and businesses will start buying less electricity from traditional
retailers, instead opting to produce power from their own solar panels. Rooftop
solar installations have reached a furious pace in the US: a new system is now
brought online every four minutes. And all other things equal, an increase in
behind-the-meter distributed generation (DG) means a decrease in sales and
revenue for utilities.
This DG-driven revenue
curtailment could produce a frightening cycle for the power industry: reduced
sales revenues could lead to less system-wide investment, which could lead to a
less cost-effective electric grid, which could in turn lead to an increase in
rates for consumers, and that could drive more high-value consumers opting to
produce their own power . . . which could all lead to further reduced sales
revenue for utilities. You get the picture. Rinse and repeat, until the days of
a centralized utility give way to a distributed generation world.
The challenge for
utilities in the coming year and beyond will hinge on ensuring that they can
constructively participate in this trend, rather than sit on the sidelines. An
innovative pack of utilities are already seizing upon such opportunities, which
include utilities’ leasing solar
panels to ratepayers and creating subsidiaries that install rooftop solar
outside their regulated service territory.
In parallel to finding
an optimal role in distributed generation, utilities are naturally suited to
further unlock the potential of large-scale solar. It still accounts for the
majority of installed solar electric capacity in the US, and it is set to take
off in a big way in
the next few years.
4. A critical mass of
smart meter infrastructure is paving the way for dynamic pricing programs
In the last 6 years,
the number of smart meters in the US has grown more than
sixfold. There are now more than 46 million smart meters installed
nationwide — enabling real-time
communication of energy data between customers and their
service providers.
This trend isn’t about
to slow down. Worldwide, the installed base of smart meters will triple from
313 million in 2013 to nearly 1.1 billion within ten years, according to a
November report by Navigant Research.
But while smart meter
deployments are becoming widespread, the use of dynamic pricing — which better
matches energy supply and demand through real-time price changes — is not as
prevalent. However, some utilities are emerging as leaders in applying dynamic
pricing to better engage their customers and ensure system reliability — just
as the concept has picked up steam in
the transportation sector.
Programs like Pacific Gas and
Electric’s SmartRate and Baltimore Gas
and Electric’s Smart Energy Rewards are at the forefront of the
utility industry’s adoption of dynamic pricing mechanisms. Their focus is on
using time-varying energy prices to keep a grid-friendly balance between
electricity supply and electricity demand, and on designing easy-to-understand
rates and rebates that help customers manage their consumption in a
personalized and energy efficient way.
5. Demand response
will aid the grid’s transition toward renewable energy supply
Fundamental changes in
the electric grid’s supply and demand profile are requiring utilities to think
creatively about how to manage this transition.
On the supply side,
deep investments in utility-scale renewables like solar and wind are bringing
into focus the intermittency of
these sources. It’s no secret that solar electricity production grinds to a
halt in the evening, and that wind speeds often pick up after electricity
consumers have gone to sleep. And on the demand side, the rise in electric
vehicles — the most energy-intensive appliances in the history of the home —
could put substantial pressure on the grid at certain times of day.
