INTRODUCTION
Demand
Side Management (DSM) is the implementation of policies and measures which
serve to control, influence and generally reduce electricity demand. DSM aims
to improve final electricity-using systems, reduce consumption, while
preserving the same level of service and comfort. DSM is a proven method of
meeting economic goals in an environmentally sustainable way, and it is also a
fast and effective way to address power shortages.
Energy is considered to be one of the
infrastructural enablers of the three pillars of Vision 2030 in Kenya. The
level and intensity of commercial and industrial energy use is a key indicator
of the degree of economic growth and development. A key message of Vision 2030
is that Kenya must generate more energy and increase efficiency in energy
consumption. Vision 2030 flagship projects focus on expanding energy
infrastructure, increasing electricity generation capacity and diversifying
energy sources.
Demand
for electricity has shown an upward trend since the year 2004 due to
accelerated economic growth. Peak demand increased from 899MW in 2004/05 to
1,194MW in 2010/11, while the number of electricity consumers more than doubled
from 735,144 in 2004/05 to 1,753,348 in June 2011. As at 30th June 2011, 28.9 %
of the population was connected to electricity compared to only 15% as at 30th
June 2004. The peak load is projected to grow to 2,511MW by 2015 and 15,026MW
by 2030. To meet this demand, the projected installed capacity should increase
gradually to 19,199MW by 2030.
To
meet the projected demand, the system expansion over the Vision 2030 period
indicates that the total installed capacity will be obtained from geothermal -
26%, nuclear plants - 19%, coal plants - 13%, hydro plants - 5%, thermal plants
- 9%, gas turbines - 11%, wind plants - 9%, while imports will provide up to
8%.
Currently the power generation capacity in Kenya is
too small to meet demand from the industry and private households. Import of
electricity from surrounding countries has eased the situation somewhat, but
load shedding is used on a routine basis. For the electricity energy which is
available, most of it is being lost through inefficient lighting systems,
electricity water heaters and other poor energy management practices.
The reduction in energy demand in Kenya electricity
sector has not been met since DSM remains underutilized because there are
powerful barriers to customer and utility investment in energy efficiency. In
addition to well known barriers such as capital, lack of information about DSM
potential and benefits, and prices that do not reflect the full direct and
indirect costs of power, Kenya has its unique barriers among them the
following;
Ø
Kenya
lacks the legal basis to adopt effective DSM policies. There is no effective
government driven programmes on DSM apart from the Demand Management Unit
created by Kenya Power in 2009 which is not that effective.
Ø
Kenya
lacks an adequate and stable DSM funding mechanism. International experience
shows that public and/or utility funding for DSM is critical to DSM success.
Ø
Shortage
of talented DSM professionals. Talented people play a pivotal role in DSM. They
are needed to develop DSM policy, programs and finances, develop technology,
launch publicity and conduct surveys. Currently specialised DSM staffs do not
exist to implement broad scale DSM programs in Kenya.
Ø
Unavailability
of high quality energy efficient products. The ones sold on the market have
quality problems. For example, energy saving CFLs of both good and bad quality
are available in the market place and consumers have no way of knowing the
difference. Poor quality deprives the consumer of any economic benefit and
injures the reputation of energy saving lamps and appliances.
Ø No
incentive mechanisms for energy saving and unwillingness
to adopt energy conservation measures such as new technologies under the DSM
program by consumers due to low income and house size.
Legal
and Institutional Arrangements in the Electricity Sector in Kenya
Sessional
Paper No. 4 of 2004 and the Energy Act No.12 of 2006 restructured the
electricity sector in a bid to facilitate high level performance. The Policy
has enabled increased private sector participation in the development of the
sector whilst simultaneously focusing on improved management and delivery of
energy services. This was intended to enable the sector address its mission of
providing clean, sustainable, affordable, reliable and secure energy services
at least cost while protecting the environment. The following are the key
actors in the sector:-
1.
Ministry of Energy (MoE)
The
Ministry is responsible for formulation and articulation of energy policies
through which it provides an enabling environment for all stakeholders. Its
tasks include national energy planning, training of manpower and mobilization
of financial resources. Overlapping mandates has been a big challenge for the
Ministry in regulating demand-side management (DSM).
2.
Energy Regulatory Commission (ERC)
It
was established as an energy sector regulator under section 4 of the Energy Act, 2006, with responsibility for economic
and technical regulation of electric power, renewable energy, downstream
petroleum sub-sectors and standards that encourage energy efficiency as well as
broader promotion of energy efficiency measures, for example, in buildings and
for appliances. A new department for renewable energy and energy efficiency was
created in the commission in 2010. Its functions also include tariff setting,
review, licensing, enforcement, dispute settlement and approval of power
purchase and network service contracts.
The
functions outlined in section 5 of the
Act seem not to have been achieved yet.
3.
The Kenya Power & Lighting Company Limited (KPLC)
KPLC
is a State Corporation with Government of Kenya shareholding of 50.1% and
private shareholding of 49.9% as at
December 2011. It purchases electrical energy in bulk from KenGen and other
power producers such as Independent Power Producers (IPPs), Tanzania Electric
Supply Company Limited (TANESCO), and Uganda Electricity Transmission Company Limited
(UETCL) and carries out transmission, distribution, supply and retail of
electric power.
IPPs
are private companies which generate power and sell electricity in bulk to
KPLC. As at 2011, they accounted for about 26% of the country’s installed
capacity and play an important role in bridging the demand gap. By December
2011, the operating IPPs were:- (a) Iberafrica Power (E.A.) Company Limited
;(b) Tsavo Power Company Limited ;(c) Mumias Sugar Company Limited ;(d) Orpower
4 Inc ;(e) Rabai Power Company Limited; and (f) Imenti Tea Factory Company
Limited.
The advent of IPPs has had some
negative impacts on energy efficiency. By definition, an IPP implies a certain
amount of vertical unbundling, which complicates attempts to implement
integrated resource planning (IRP)—a key platform for promoting demand-side
management (DSM).
The unbundling of the formerly vertically integrated
Kenya Power and Lighting Company (KPLC) as per the recommendations under
Sessional Paper No. 4 of 2004 establishing Kenya Electricity Transmission
Company Limited (KETRACO) to be responsible for the development of the
national transmission grid network and also to be in charge of extending the
national grid countrywide and building inter-connectors responsible for facilitating
regional power trade through its transmission network has not bore fruit to
meet DSM. The effect of unbundling is that the
separation of generation (KenGen) and distribution (KPLC) segments means that
the distribution utility is at liberty to obtain electricity from different sources
(IPPs). The general response by distribution utility to increases in
electricity demand appears to be seeking additional suppliers of electricity
rather than embarking on demand-side energy efficiency programmes. The need for
additional electricity generation appears to have in turn encouraged a focus on
large-scale thermal IPPs. As a result, opportunities for both energy
efficiency through DSM and distributed
generation (offered by renewables such as small hydro, cogeneration and
geothermal) have not been fully exploited.
KPLC
set up a Demand Side Management (DSM) unit in 2009. This unit has implemented
several strategies to reduce consumption, especially at peak times. Strategies
include the provision of 1.25 million free compact fluorescent lamps (CFLs) to
the population and introduction of a specific tariff for peak hours. Compact Fluorescent Lamp (CFL) light
bulbs provide an energy efficient alternative to traditional Tungsten filament
light bulbs. Replacing incandescent bulbs with CFLs decreases energy
consumption by 80 percent per bulb, and CFL bulbs last roughly ten times
longer. In Kenya there is no detailed data on the current uptake of CFL, but it
can be safely assumed that, especially in urban areas, the penetration rates
are relatively high already. Incandescent light bulbs may be prominent in rural
areas, but the low level of rural electrification limits the potential for
large energy savings. This has been contributed by inadequate funding and
limited use of renewable energy.
However, there is no motivation for
the utility to enhance demand-side energy efficiency as it requires additional
investment and could potentially lead to lower revenue levels that can
negatively impact profitability.
4.
Kenya Electricity Generating Company Limited (KenGen)
KenGen
is a State Corporation with GoK shareholding of 70% and private shareholding of
30% as at December 2011. It is responsible for electric power generation and
produces the bulk of electricity consumed in the country. The company utilizes
various sources to generate electricity ranging from hydropower, thermal
(petroleum) and geothermal accounting for 53%, 29% and 14% of installed
capacity.
However,
the large dependency on hydropower on the supply side which is vulnerable to variations
in hydrology and climate change has made KPLC and KenGen to pay little
attention to the demand-side management of electricity and they are only
concerned with supplying electricity and making profits without much thought to
reduction of energy consumption.
5.
Rural Electrification Authority (REA)
REA
was established under section 66 of the
Energy Act as a body corporate with the principal mandate of extending
electricity supply to rural areas, managing the rural electrification programme
fund, mobilizing resources for rural electrification and promoting the
development and use of renewable energy. Section
67 of the Act provides for the functions of REA.
However,
most rural areas do not have electricity yet and the programme has not yet met
the demand side management since it has failed to promote use of renewable
energy sources including but not limited to small hydros, wind, solar, biomass,
geothermal, hybrid systems and oil fired components taking into account
specific needs of certain areas as per Section
67(d).
Other
institutions in the electricity sector include ;-(i)Geothermal Development
Company Limited (GDC); and (ii)The Nuclear Electricity Project Committee
(NEPC).
Beyond
these national bodies there are many international organisations active in
supporting the Government of Kenya and other stakeholders in the field of
energy efficiency including the International Finance Corporation, AFD and the
German International Development Agency (GIZ). The activities of these
organisations target different end user groups and energy carriers.
The Kenyan government has introduced
regulations that promote conservation and demand management. An example is the Kenya Solar Water Heating Regulations
issued by the Ministry of Energy that mandates the installation and use of
solar water heating systems for all buildings with a capacity for hot water
requirements of more than 100 litres a day. There is amble evidence to show that
Solar Water Heaters (SWHs) play a very crucial role in demand side management
(DSM) in many countries. SWHs can be used to flatten out the maximum demand
curve for any utility. The technology can also be used to cut down the actual
demand, and this can have various implications for a country. Depending on the circumstances,
this can mean delayed investment in power generation or reduction of the import
bill for those countries that import power or fuel.
A second example is the Draft Kenya Energy Management Regulation of
2011 that makes it mandatory for facilities to undergo energy audits and
encourages them to implement at least 50 percent of the identified energy
efficiency potential.
Enforcement of these regulations remains a challenge, although some supportive
policies have been launched.
Administrative
Reforms
The Kenyan government needs to embark upon
comprehensive programmes of broader economic and administrative reforms which will
have far reaching impacts directly and indirectly, on the pattern of demand for
electricity services in Kenya. There is need for the government to diversify
electricity supply and demand management options, as well as the institutional
and financing mechanisms to help address the growing gap between supply and
demand. At the same time, many other factors gaining prominence need to be
accommodated, such as the change in decision-making approaches that stem from
the economic reforms and associated political change as witnessed with the
enactment of the 2010 Constitution, and more widespread and growing public
awareness of environmental and social issues.
There is a need to review the tariff policy in order
to minimize consumer subsidies and instead channel public resources to long
term infrastructure investments. Therefore, the tariff has to progressively
reflect the economic cost of power supply. Subsidies will be applied only in
the short term to avoid a tariff shock. The increase in tariff will be managed
through demand side management in households, industries and commercial
enterprises. This will help consumers to reduce on the quantity of electricity
utilized with a net effect of having the final bills nearly equal to what they
were previously paying. The policy measures outlined below should be adopted on
the tariff:
• The preferential tariff for the industrial
consumers should not be applicable in the medium term.
• The tariff will be increased in a stepwise manner
to reflect the economic cost of providing electricity services.
• The resultant rise
in tariff will be managed through energy conservation measures.
The Kenyan government policies should typically aim
to maximize the use of alternative energy resources in the country such as
coal, gas, oil, biomass, solar, wind, and hydro with considerations of energy security.
However, a proper regulatory framework needs to be put in place to adequately
regulate the use of indigenous energy sources to prevent environmental
degradation such as pollution and desertification in the long term.
Energy
audits should be carried out and use of on-site renewable energy should be
encouraged. Energy audits in industries, commercial buildings and institutions
which the Ministry has been carrying out should continue both in the short and
medium term. Steps should be taken to use the energy audits generated over the
last decade in large- and medium-sized commercial and industrial facilities in
Kenya to identify concrete low-cost follow-up actions for larger end-users.
These end-uses could be supported with access to capital and technical
assistance in implementing the required investments. Such an approach is
currently successfully implemented by the Regional Technical Assistance Program
aimed at providing support for the financing of selected investments in
renewable energy and energy efficiency projects, especially in the agricultural
and hospitality sectors. AFD and the Kenya Association of Manufacturers
implement the program and funds totalling Ksh 3.3 billion are available through
CFC Stanbic and Co-op banks. The program not only provides loans but also
carries out audits that help commercial end-users identify energy efficiency
options.
Demand side efficiency approaches include the use of
legislated standards to remove low efficiency equipment such as motors,
lighting and appliances from the market, the support of innovative market
driven approaches to finance high energy efficiency projects from future
savings, and the use of performance-based regulation to encourage utilities to
undertake DSM in restructured electricity and gas markets.DSM strategies which
can be implemented in the country include;-
(1)Use of Alternative Lighting; replacement of all incandescent lamps by compact
fluorescent lamps (CFLSs) both in rural and urban areas. The low investment cost of CFL and
further cost reductions can lead to high adoption rates in the short term. In
2030 it is assumed that an adoption rate of 100 percent will be achieved
through an intervention to phase out incandescent bulbs, leading to 80 percent
lower electricity consumption for lighting versus the reference case by 2030. Energy consumers should be encouraged to
switch off lights during the day as a potential strategy.
(2) Peak Load Reduction or
Conservation; Peak load “shaving” in the power system thereby minimizing the
need for huge investments to meet peak demand, which lasts for only a few hours
in a day. This would be applied to all hot
water systems. The action is either to switch off hot water systems when not in
use or to replace all with solar hot water systems.
(3)Energy
Efficient Appliances; Large differences exist in the energy
efficiency of electric appliances. Over the past two decades, there have been
major improvements in the energy performance of most appliances. In the United
States, for example, refrigerators in 2012 use about 60 percent less energy
than 20-year old models. In Mexico, refrigerators sold between 1995 and 2000
were estimated to consume 30 percent more electricity than those of the same
size sold between 2001 and 2007. In developing countries, energy efficiency of
electric appliances is often lower than in developed countries, especially if
there is a significant market for second hand inefficient models or if
efficient models are not available or significantly more expensive. Second
hand, energy inefficient refrigerators from Europe have traditionally been
exported in large numbers to Africa.
Current situation in
Kenya: Replacing appliances such as refrigerators, air conditioners and
televisions in households and commercial facilities with more modern efficient
units can lead to substantial energy savings. The high prices of new appliances
in Kenya, combined with the large influx of older cheaper second-hand
appliances from the EU, mean it often unattractive to purchase new models.
(4)Energy efficiency
improvements across industries –
Results from energy audits undertaken in different commercial and industrial
facilities in Kenya show that with measures of payback times of less than two
years, savings in electricity consumption of between 8%(for a tourist resort)
and 26 % (for a tea factory) could be achieved through measures such as the use
of more efficient pumps and motors. However, it is difficult to encourage SMEs,
which form a significant part of Kenya’s
commercial and manufacturing sector, to invest in energy efficiency without
interventions or support programs. Taking all these factors into consideration,
a 15 percent energy efficiency improvement by 2030 is assumed.
Structural Reforms in the
Electricity Sector
Kenya has been working from the former single,
vertically integrated state monopoly KPLC in the electricity. Current reforms have created new challenges and are
generally seen to contradict/hinder efficiency through regulations especially
in cases where distribution utility still enjoys monopoly. For example,
requiring a single distribution utility such as KPLC to reduce consumer demand
for electricity through energy efficiency is inconsistent with introducing
competition as it might appear to affect profitability of the utility due to
the reduction in electricity sales. Consequently, this may be viewed as a potential
trade-off before enhancing energy efficiency and competition.
A more open
market with private sector participation and competition is needed in order to
meet the demand side management. This will require the following reforms;-
Ø
ensuring
that the regulatory framework promotes more efficient use of electricity and
enhancement of environmental and social benefits;
Ø
setting
up an autonomous regulator or providing for a clear separation of policy and
regulatory functions within government with a transitional programme towards
independent regulation;
Ø
vertical
and horizontal restructuring of the state power entity.
Policy
and Regulatory Framework in the Electricity Sector
The following legislations and regulations are
recommended to support Demand Side Management;-
Ø
an
Energy-Efficiency Act enabling the setting of minimum efficiency standards and
codes, with regularly updated regulations to raise the bar of minimum efficiency;
Ø
power
utility regulation through an independent agency or board, which regulates
utilities in the public interest, with rules that encourage DSM investment by
utilities, and applies a mandated public benefits charge to finance DSM;
Ø
Strategic
Planning process for all new investments in electricity supply and demand,
which uses a life cycle approach for assessment of options and full
environmental impact; and
Ø
Regulation would be required to phase out incandescent light
bulbs, create a labelling scheme for electrical appliances, and provide
standards and codes for the use of solar water heating. The ability of these
regulations to be enforced is critical to their success.
CONCLUSION
Energy efficiency in Kenya is
generally given a low priority, both at the industrial and domestic level.
Electricity sector reform has not
adequately supported the promotion of energy efficiency in the sector.
However, there is need for extensive
publicity and to enlist the support of all households on the benefits of DSM.
This can be done through media publicity and exhibitions of energy efficient
devices to showcase their applicability and potential energy savings.
