Power System
Generation
CLP has 3 generation plants
located in the New Territories
and 2 located on the Mainland.
CLP and Hong Kong Electric’s
(HEC) networks are
interconnected to back up
each other in cases of
emergency.
This means that there are no
less than 6 supply sources to
the CLP network at any point in
time.

Power System
Transmission Network
CLP’s transmission system is
connected to Hong Kong
Electric’s and to the China
Southern Power Grid via
transmission circuits.
This connection safeguards
CLP customers from any
major power loss during
cases of emergency.

Power System
Distribution Network
CLP’s distribution network is
based on 11kV Closed Ring
supply system.
This ensures that there is
enhanced supply security.
This arrangement also provides
substantial cost saving for data
center operators trying to
achieve n+1 supply reliability
through cost avoidance.

Tariff
CLP’s tariff is amongst the lowest in the
world for its level of reliability. In addition
to being one of the lowest cost our tariff
has the following features :
 Simple Structure – Data center operators
have a choice of 3 simple tariff types, 2 of
which are “time of use” based. Charges
are based on actual demand and actual
consumption.
 Transparent – All components of the tariff
are published.
 Stable – CLP tariff is reviewed once per
annum enabling customers budget
certainty.

Frequently Asked Questions (FAQ)
Back to main page
Q1: What is the supply lead time for the provision of electricity supply?
Answer: The supply lead time will depend on the potential data center site
and the requested electricity demand. It will also depend on CLP’s works
programmes and other customer projects. CLP can provide the estimated
supply lead time within a few days of notification of the location and the
loading.
Q2: Can CLP fast track power supply?
Answer : CLP will endeavour to fast track energisation and supply
depending on load demand and commitments on uptake. We encourage
you to speak to our team dedicated to handling all enquiries on data
center power supply.

Q3: How can CLP maintain reliability levels at 99.99 % when it is the only
supplier?
Answer: It is not necessary for power supply to be sourced from two
different generation companies for it to be more reliable. CLP strength lies
in its network. With any electricity utility supply system, most power
disturbances originate from the network i.e due to accidental cable
damage, lightning etc. CLP’s robust network is able to eliminate any
disturbances before it affects customers.
Q4: How does the interconnection between CLP, HEC and Guangdong
Power Grid work?
Answer: HEC supports CLP and vice versa in case of any power supply
emergency. CLP purchases a portion of its power supply for its customers
from Guangdong Daya Bay Nuclear Power Station.

Q5: Given CLP’s system connectivity with Hong Kong and Guangdong can
a data center operator claim to be a tier 4 data center?
Answer: The data center "tier" definitions were developed by data center
professionals. It is not for CLP to determine whether a data center operator
can claim to be a tier 4 data center based on CLP’s supply network.
We can advise though, that CLP’s network can obtain power from multiple
supply sources, 3 from power stations located in the New Territories and 2
on the Mainland. In addition, CLP and HEC back-up each other through
the interconnection in case of a power supply emergency.
Whether the data center operators conclude the above as being a dual or
multiple source will depend on their interpretation of a “Tier 4” data center.

Q6: Are CLP electricity tariff rates negotiable?
Answer: CLP’s tariff rates are fixed and all components are transparent.
Customers may apply for the rate that is appropriate to their actual
consumption. CLP’s tariff is amongst the most competitive in comparison
with other world class cities. Our tariff table is available at
