Are We Doing Enough on Energy efficiency?

A Cleaner Environment is Worth Paying For
…But a Move to Gas Is Not a Free Lunch

Hong Kong has better solar resources than countries like
Germany that have deployed solar PV at scale

Price PV modules three fold fall…however the cost of
installation has not. Location matters

Characterising local wind’s speed and reliability…..again
location matters
• China’s 62

• 24x

since
2006

Merit in again exploring the potential for
renewables in Hong Kong
• Cost of renewables technologies has dropped
• Lots of good international experience in deploying energy
from waste, solar PV and increasingly off-shore wind
• But, also need for the right policy framework
– Provide investors price for renewable energy sales
– Visible access prices & terms and conditions to use
networks
– Payment on results – so the risk of non-performance of the
technology is borne by project sponsor, not the customer
– Firewall protecting revenue from renewables from
volatility of world fossil fuel markets
7
Support for renewables in the SCA
• Under SCA renewables are incentivised by
– an 1% additional RoR (11%) for project.
– Energy efficiency, renewables and incentive payments
• Like any other capital spend Government agreement is
needed before the project can commence.
• Project should meet the “lowest cost which is reasonable in
the light of financial and other considerations” test
• Singapore, South Korea and Taiwan have much faster growth
in renewables, is our current policy effective?
8
Let’s Not Forget Distributed Generation
• Offer standardised grid connection arrangements for
distributed generators, but no offer of export tariff or feed-in
tariff for electricity spilled onto incumbent’s distribution
network system
• No well-defined account of the network charge of the
incumbents distributed network
• Result: only a low number of small generators have applied
for grid connection
9
Limited renewables investment under SCA over the past 6
years
• Offshore wind (US$5600/kW) and solar PV (US$3400) have
substantial capital costs
• CCGT (around US$900/kW) but fuel costs are substantial
• Capital investment is rewarded under SCA while operating spend
is simply passed through to consumers
• Expensive way of rewarding renewables project for consumers
– Greatly increases the company’s Net asset
– Has poor energy output per unit capital spend (offshore wind
high CAPEX and low utilisation rate compared to CCGT)
– Risks of obsolete renewable technology borne by consumer

their bills…but with right framework could reduce costs

The current SCA framework and energy efficiency
• A reduction in energy use has a negative effect on the
company’s bottom-line.
– Firstly, revenue is cut. Recovery of fixed costs from
customers?
– Secondly, any excessive investment in new capacity is ‘fined’
• There is also a weak ‘all-or-nothing’ incentive of a 0.01% boost
in the ANFA if a modest target is reached
• Responsibility for energy efficiency doesn’t have to sit with
energy companies
• Alternative energy service companies (ESCOs) that sell
consumers services like well lit and comfortably chilled office
space. Profits from negawatts
14
Setting hard targets for energy efficiency
• In many countries energy companies have targets to deploy
EE
• Some territories have used stand alone agencies to deploy
energy efficiency
The California Public Utilities Commission directs the
electricity companies to install energy saving technologies in
customer homes. Tough penalties are imposed for missing
targets and rewards for over achievement.
Efficiency Vermont is an energy efficiency utility funded by
electricity customers in Vermont. Electricity customers are
charged $35 per year but it has typically installed
technologies with pay back of two years
15
Other low cost opportunities for improved savings
• The EU fridge is in the second band
of performance and uses
280kWh/yr
• The HK fridge is a first tier
performer and consumer 346
kWh/yr.
• The EU fridge is twice the volume of
the HK fridge
Ever tightening energy efficiency standards
Grants for retiring “G” rated equipment
16
Summary
• There is significant evidence that the costs of solar has fallen,
and some evidence wind costs are falling
• It is time to revisit the potential in Hong Kong
• More investment and regulation is needed to develop energy
efficiency and reverse the growth in commercial demand.
• The current policy mechanisms to deploy renewables and
energy efficiency are ineffective and deployment has been
slow
• Incentives are either weak or too expensive
• Contestability to ensure renewables and energy efficiency are
introduced at least cost to customers
