Ceylon Electricity Board (CEB)
CEB established by the Sri Lanka Act No. 17 of 1969
CEB is a Statutory Body responsible for Generation,Transmission & Distribution of electricity in Sri
Lanka
CEB is a vertically integrated power utility until 1997with a monopoly on Generation, Transmission &
Distribution
In 1997 Generation was opened for Private Sector(IPP)This is based on the GOSL policy

Power Sector Policy Directions 1997
Hydro power generation potential of the country willbe developed to its full potential
All large scale hydro power generation facilities areto be remain under the governmental control (i.e
CEB) Private sector financing will be utilized for power
generation from renewable energy sources
( development of small power plants maximumcapacity up to 10 MW per project)

CEB facilitation role as a energy purchaser
Issue of Letter of Intent to build up theconfidence of the private sector investor
Facilitate interconnection arrangements
Sign SPPA - to attract investments (This is a
bankable document) Facilitate to get Tax Exemptions introduced
by the GOSL (Ex: VAT, NBT exemption)
Allow developer to build the interconnection
facilities under CEB supervision Witnessing the Testing & Commissioning
Payments as per SPPA terms

What are the solutions ?
Improvement of National Load Profile (may be
with the current development program of the
country)
Augmentation of grid substations to absorption
of NCRE
Introduction of NCRE collector GSS ( already
done in Puttalam to absorb wind power)
Construction of long lines to absorb NCRE (need
a policy decision)

Sri Lanka introduced the net metering
system to electricity customers
Maximum capacity limit42 kVA(Good Newsextended up to 1 MVA)
Difficult to promote due to high cost
of Solar PV
