1. Abstract
Expanding renewable energy access for rural communities in Africa is a challenging task. In most of the
cases, government investments and donor funds have proved insufficient to expand access to modern
energy in rural areas in a sustainable manner. However, energy production and distribution in rural
areas in Tanzania is now a national priority and a promising business opportunity, because national
policy and legal framework provide a good environment for investments and subsides from co-
financing feasibility studies to project realization. Still, there is a great need for mobilizing financial
resources to expand energy access for rural communities. A partnership between non-profit and for-
profit actors is here proposed in order to rapidly expand energy access and meet national
programmatic targets for electrification and energy production. Essentially, Non-Profit/For-Profit
Partnerships (NPFPP) occupy a fruitful “middle ground” between commercial private sector projects,
focused primarily on profit; and public/non-profit sector projects, focused primarily on enhancing
access. In a nutshell, effective NPFPP couple profit with energy access. This article explores the
concrete possibility of a NPFPP between CEFA, an Italian NGO specialized in rural electrification, and a
private partner for the realization of a Small Hydro Power project in Ninga, Tanzania.
2. Rural Energy sector in Tanzania
Tanzania’s power supply consists of the national interconnected system and several mini-grids serving
areas located far from the national grid. National electrification rate is 18.4%, set to arise 75% by 2035,
but rural electrification coverage is sensibly low, with less than 7% of the rural population (2.2 million)
having access to electricity.
The country’s installed electricity generation capacity is 1,564 MW (as of March 2013), of which
1,438.24 MW is available in the main grid, with the balance of 125.9 MW accounted for by Small
Power Producers (SPPs), mini grids, and imports. About 62% of grid generation capacity is from
thermal (32% from natural gas and 29% from oil), whilst 35% is from large hydropower, with the
remainder from small renewable-energy power and imports. The country suffers from severe droughts
over the last decade, low coverage of the electric grid and an increasing shortage of electric power
production capacity in relation to demand, which roughly grows with the economic growth. The
reliability of the electric grid power is low, with frequent brownouts and blackouts. There was an
estimated private individual installed capacity (small generators) in 2011 of 300-400MW not
connected to TANESCO producing at about €0.26/kWh using diesel.1 The update Power System Master
Plan (PSMP, update 2012) estimates now a 565 MW installed capacity from private gensets.
The rural electrification sector is defined by law and well regulated under the Ministry of Energy and
Minerals (MEM). The Rural Electrification Agency (REA), the Energy and Water Utilities Regulatory
Authority (EWURA) and Tanzania Energy Supply Company (TANESCO) are thus the 3 key actors under
MEM in Tanzania dealing with rural electrification, renewable energy and market development.

The Electricity Act (2008) describes the power generation, distribution, tariffs, and a specific section on
RE plans & strategies, organization and actors such as REA and EWURA. There is a Rural Electrification
Fund (REF) managed by REB board (MEM & MoF trough REA) and fed by the government, World Bank,
SIDA, NORAD and by a 3% levy. Detailed guide exists to prepare and submit applications. In addition
there is a Power Sector Master Plan (PSMP) which has been revised in 2012 and a Rural Electrification
Investment Prospectus.
A Rural Energy Master Plan was produced in 2005 and is under revision wherein the update started
with 4 regions under IREP project. The objective for electricity access is 30% by 2015 and 50% by 2020,
from 18.4% in 2012. As of 2013, there is only 7% electricity access in rural areas. The first objective is
to electrify all district centers and to reach 16% by 2015 in rural areas.2
Figure 1: Tanzania Existing Network and Proposed Extensions (SREP 2013)
EWURA is also regulating the private sector’s participation through the tariffs and Standardized Power
Purchase Agreement (PPA) for private actors as IPPs (independent power producers), SPPs (small
power producers <10MW), SMPPs (very small power producers < 100kW), DNO (Distribution Network
Operators), SPD (small power distributor).
A state-owned utility called TANESCO is in charge of urban electrification while REA is in charge of peri-
urban and rural electrification. REA has implemented more than 140 grid extensions. TANESCO still has
the monopoly for distribution. For the past several years, TANESCO has experienced serious
management issues which have led to a difficult financial situation (high demand, too low tariffs).
Network quality is very poor despite high-level standards. The benefits from reform engaged by the
government and international donors to restructure TANESCO and to invest in the production and

transmission infrastructures will take years from now.3 The end-user retail tariff is uniform on
TANESCO network (60 to 273 TZS/kWh for domestic categories, €0.03 and €0.12 respectively).4 The
average retail tariff is estimated at 174.89 TZS/kWh, €0.08/kWh.5 A 3% tax is levied on the tariff for
REA and EWURA. As for the off-grid, tariff is determined by the kind of technology used and
investment cost.
The new institutional framework is favorable to Independent Power Producer and to renewable
energies with feed in tariffs (FIT) determined by EWURA for on-grid and off-grid injection. IPP regime is
set with standard procedures, PPA and annual licenses (>1MW).6 The MEM has adopted in 2007
Standardized Power Purchase Agreements (SPPA) and Standardized Power Purchase Tariffs (SPPT) for
interconnecting and selling power (< 10MW) to the main grid and to mini-grids (cf. below Tables 1 and
2). The tariffs are negotiated through SPPA under SPP guidelines and Standardized Tariff Methodology
and reviewed annually by the Working Group WGSPD hosted by EWURA to accommodate
uncontrollable operational costs. The following tables shows the evolution of FIT in Tanzania during
the past three years:

If the Independent Power Producer (IPP) sells hydro-power to TANESCO’s main grid, there are two
feed-in tariffs depending on the season (rain/dry). The feed-in tariff is calculated by EWURA as the
average of the avoided costs of supply and the incremental cost of mini-grids. For 2013, the feed-in
tariff for main grid was set at an average of TZS 174.89/kWh (€0.08/kWh) and for mini-grids was set at

For this study we assume the following change rate: EUR 1= TZS 2,200. 5
The official tariff structure (fixed and variable parts per categories) doesn’t really help for tariff comparison and
analysis. The actual average tariff should be calculated as the ratio between the total yearly income from
electricity sales and the total energy consumed by customers. The average tariff of TANESCO is estimated to be
around €0.08/kWh. 6

TZS 490.13/kWh (€0.22/kWh). If the IPP sells to other customers than TANESCO, it can propose tariffs,
which must be approved by EWURA. Standardized documents for power purchase agreements (SPPA)
are available for SPPs with small power systems (<1MW). There are currently 12 registered and
operating SPPs: 1 operating an isolated MG, 11 selling to the grid/TANESCO.
Current government incentives include tax exemption (VAT & import duties) for main solar
components (panels, batteries, inverters and regulators). No tax exemptions are provided for other
renewable technologies (wind, hydro, biomass), unless the project is under international donor-funded
programme, e.g. 10th
EDF from European Commission.
The green mini-grid experience in Tanzania is still very limited. TANESCO is running 21 diesel-based off-
grid stations supplying isolated mini-grids for small towns (installed capacities ranging from 400kW to
12MW and 8 stations have peak loads below 1MW). TANESCO’s priority is to connect those isolated
grids to the main grid.
For off-grid areas where over 80% of the population does not have access to electricity, there is a huge
potential for small-scale renewable technologies. Renewable energies have a key role in the
government’s strategy to electrify rural areas.8
3. The Potential of Small Hydropower in Tanzania
Hydropower is the most popular and the oldest renewable energy source used to produce electricity
for rural grids. Abundant and old experiences exist in several developing countries. Typical capacity
range from few kW (micro-hydro) to few MW (small-hydro), depending on various factors as
hydrology, load demand, geographical constraints. The infrastructure and civil works can be rather
complex and costly depending on the water collection system (pond, weir, channel, forebay, and
penstock). The powerhouse is pretty standard hosting one or more turbines, alternators and control
system. The technology is quite simple and well mature, allowing local repairing, etc. There are several
examples of local manufacturing or assembling companies in Africa dealing with cross-flow or pelton
turbines for rural applications. Investment costs for micro or mini hydro plant are generally claimed to
be low but they are often higher than expected, as they are extremely variable and site-specific.
Moreover the long preparation (studies, ESIA, permits) and lead times are other hurdles.
The assessed potential of small hydropower resources up to 10 MW in Tanzania is 480 MW. The
installed grid-connected, small-hydro projects contribute only about 15 MW. Most of the developed
small-hydro projects are owned by private entities and are not connected to the national electricity
grid. Five sites in the 300–8,000 kW range are owned by TANESCO. More than 16 are owned by faith-
based groups, 29 with a 15–800 kW range in capacity and an aggregate capacity of 2 MW. Of the 11
projects for which Small Power Purchase Agreements (SPPAs) have been signed, four are mini-hydro
projects, with a combined capacity of 20.5 MW, whilst the others are biomass powered. Examples
include Mwenga, a 4 MW hydro plant that supplies power to nearby rural villages, with the excess sold
to TANESCO; AHEPO, a 1 MW privately-owned small hydro project in Mbinga, currently under

construction, that will supply power to TANESCO’s isolated grid and directly to communities. In
addition, TANESCO has signed Letters of Intent for six small hydro projects with a combined capacity of
29.9 MW. Several small hydro projects are also being developed as isolated mini grids.
Moreover, different instruments and projects are put in place by the government and donors to
support the hydro-power sector. Currently, the MEM is conducting small-hydro feasibility studies in
eight regions: Morogoro, Iringa, Njombe, Mbeya, Ruvuma, Rukwa, Katavi, and Kagera. The British NGO
GVEP International, in partnership with the REA, is supporting the development of six hydro mini grids,
with a total capacity of 7.4–8.8 MW. The REA has awarded some 20 TEDAP matching grants to private-
sector developers for small hydro pre-feasibility studies. In addition, the Energy Sector Management
Assistance Programme (ESMAP) has approved funding for renewable-energy resource mapping,
starting with small hydropower, including two-year hydrology measurements. The United Nations
Industrial Development Organization (UNIDO) is co-funding the development of six mini grids based on
mini/micro hydropower, whilst the EU is financing four Hydro Power projects (including one developed
by CEFA).9
Hydro plants can be commercially attractive if the output of the least-cost design can be sold. However
this output often exceeds the local demand that could be supplied by a mini-grid. In such cases, the
connection to main grid is therefore required.
4. CEFA and Rural Electrification in Tanzania: 25 years of commitment
CEFA (European Committee for Training and Agriculture) is an Italian NGO that promotes initiatives of
development, cooperation and international volunteer service. Founded in 1972 by a group of
agricultural cooperatives based in Bologna, CEFA supports projects aiming to promote integrated self-
development in rural regions of the Mediterranean, East Africa and Central/South America. Active in
Tanzania since 1976, CEFA promotes interventions in the fields of:
• Rural electrification
• Water supply
• Agriculture
• Agro-processing
In 2007 CEFA decided to start implementing projects in Dar es Salaam addressing urban poverty,
counting on the experience acquired by the organization in urban contexts in Albania, Morocco and
Kenya.
CEFA’s commitment to rural electrification in Tanzania lasts since 25 years. In this period the
organization has realized three mini hydro-electric power plants, providing electricity to hundreds of
people living in the rural areas of the Iringa and Njombe Regions. Careful planning procedures for
technical capacity, good institutional arrangements, managerial capacity and economic considerations,
as well as multi-stakeholder involvement from the planning phase onwards, have resulted in the

sustainable operation of the three hydro power plants.10
Such commitment in the sector continues
still today, with a current upgrade project in Ikondo, allowing more and more families to benefit of the
opportunities offered by having electricity in their villages. Here follows a brief description of what has
been realized until now by CEFA in this field.
Matembwe:
Matembwe, in the Njombe District, is where CEFA realized its first hydro power plant in Tanzania,
thanks to funds granted by the Italian Ministry of Foreign Affairs, Belgian Ministry of Foreign Affairs
and the European Union. The construction of the dam began in 1981, while the power plant was
completed in 1984. At present the power plant and the distribution network are owned and managed
by the Matembwe Village Company – MVC Ltd, a local entity established by CEFA together with the
other partners of the original project (Catholic Dioceses of Njombe, District of Njombe and Village of
Matembwe).

Bomalang’ombe:
Bomalang’ombe, in the District of Kilolo, is where CEFA built its second hydro power plant, on the
model already experimented in Matembwe. The project, co-funded by the Italian Ministry of Foreign
Affairs and the European Union, intended to favour the development of the village of Bomanlg’ombe
by providing it with electricity. The construction of the dam started in 1996, while the power plant was
completed in 2001. The availability of electric power, together with the rehabilitation of the road for
Kilolo, determined a rapid development of the village of Bomanlg’ombe, that in these years has seen
its population grow from 5.000 to more than 12.500 inhabitants. At present the power plant and the
distribution network are owned and managed by the Bomalang’ombe Village Company – BVC Ltd, a
local entity established by CEFA together with the other partners of the original project (Catholic
Dioceses of Iringa, District of Kilolo and Village of Bomalang’ombe).

Ikondo:
Ikondo, in the District of Njombe, is where CEFA realized its third hydro power plant. Unlike the
previous two sites, Ikondo is a run-of-river plant, which uses the water provided by the river Kyepa.
The project, co-funded by the Italian Ministry of Foreign Affairs and the European Union, intended to
help start-off the development of the village of Ikondo, a very isolated settlement in the District of
Njombe. The construction of the plant started in 1999 and was completed in 2004. At present the
power plant and the distribution network are still owned and managed by CEFA.

The current electrification project of CEFA is an upgrade of the previous project in Ikondo. The project,
co-funded by European Union under the 10th
EDF, started in September 2011 and will allow in 2015 to
upgrade the output of the power plant up to 430 kW and to increase the actual distribution grid
reaching 4 new villages and connecting to the Matembwe grid and to TANESCO grid in order to sell the
excess of production. At the end of the project the power plant and the distribution network will be
owned and managed by the Matembwe Village Company – MVC Ltd.

5. Looking for a bigger impact: the NPFPP model
The concrete experience of 25 years in Tanzania CEFA coincides with the scientific literature: the
availability of safe, reliable and affordable energy is a prerequisite for sustainable development both at
micro-level and at national level.11
The provision of energy services through renewable energy (in our
11

Renewable Electricity Capacity: Literature Review, Institute of Development Studies UK, 2013.

11
case, Hydropower) is capital intensive and requires significant upfront costs compared to conventional
energy technology. In most of cases, government investments and public budgets have proved
insufficient to expand access to electricity and modern energy in rural areas in a sustainable manner.
Mobilizing financial resources to expand local energy services delivery in Tanzania is therefore an
imperative.
In a scenario that has seen decreasing more and more funds for development cooperation, and at the
same time increase the demands from donors in terms of the impact of actions supported (e.g. the
extension of the areas of intervention and number of beneficiaries involved), a new approach is
necessary regarding the action of Non-Profit actors like CEFA in developing countries.
Non-Profit/For-Profit Partnerships (NPFPP) are one of the best mechanisms to supplement and
overcome budgetary constraints for widening access to energy services, especially to the local
communities, as they can allocate project-risks between the public/non-profit and private sector.
Profit motivations are blended with social concerns and empowerment of targeted communities. This
type of partnership in recent years has often been advocated by some of the major international
donors, and today has almost the contours of obligation.
An interesting approach towards forming partnerships between CEFA and the private sector to provide
energy services to the communities with emphasis on viable, long-term sustainability is shown in
Figure 2. The NPFPP schema operates on the twin foundations of sharing risks and rewards. Risk
sharing is reflected by the resources invested by the private and non-profit sector in the partnership.
There could be several NPFPP options depending upon the mix of risks and roles assigned to each of
the partners.
Figure 2. The NPFPP model
The partner which invests more is the one which takes the highest risk or is the least ‘risk averse’.
Apportioning of rewards is generally in proportion to risk taken. Additionally, rewards are also
reflected in the availability of tangible incentives for the different players in NPFPP: fulfill corporate

12
social responsibility and cost recovery/profit for the private actor; achievement of its mandate of
delivering basic services to local communities for the non-profit actor; availability and access to basic
services for the target communities. This incentive system is the key to sustainability of any NPFPP
venture.12
The long experience of CEFA and the scientific literature13
suggest that the inclusion of multiple
stakeholders in program design, implementation, and evaluation can enhance the efficacy of
renewable energy deployment. The involvement of women’s groups, multilateral donors, rural
cooperatives, local government, local micro financial institutions, nongovernmental organizations and
other members of civil society, and even consumers can increase both the performance and legitimacy
of partnerships. They improve performance since input from multiple stakeholders can accelerate
feedback; they improve legitimacy since programs with a broader base of support, and community
involvement, are less likely to be opposed or protested. The partnership benefits from addition to the
pool of resources of the public and private sector, and the resources (social, human, financial, political
and psychological capital) of the communities themselves. Not only does the delivery of energy
services become more efficient, there are additional benefits that may follow like empowerment of
the communities, social rehabilitation of those suffering from disease, changing the way the private
sector fulfills its corporate social responsibility and enhancement of social development for the
communities involved. This is an important task to be carried out by CEFA in the NPFPP scheme.
6. What next: the concrete example of the Ninga SHPP
At CEFA we are now aware that only with a qualitative jump we can achieve such an impact to be
incisive for a large population that needs energy access. It was therefore decided to take advantage of
the opportunities and instruments that are in place now in Tanzania to design a new project, which’s

size and impact significantly differ from the previous ones. The site for the next intervention is in the
Njombe District, Njombe Region (former Iringa), Rufiji River Basin. The interested river is the South
Ruaha, affluent of the Mnyera river and part of the Kilombero River tributary basin.
Technology: Run of river hydropower plant.
Installed capacity: 4,000 kW
Gross head: 73 m
Design Flow: 6.91 m3/s
Impact
The number of connections in the first phase (Year 2017) will be 1,680 households, 169 commercial,
99 Public Services and TANESCO with a maximum electric power generation of 21,750 MWh to meet
the energy load of identified customers and surplus bulk sales to TANESCO.
Costs
Investment for initial phase of 4 MW – € 7.3 million (Tshs 16,060,000 million), and estimated O&M for
Power generation & Distribution of € 183,000.00 (Tshs 402.6 million) per annum.
Unit (production) costs are approximately 2.69 €c/kWh (59.10 Tshs/kWh) over a 10 year time horizon.
Electric Line and Connection to the Grid
The served villages will be Ninga, Lima, Isitu, Ikuna, Lole, Upami and Ilengitu. Ninga SHPP will be part of
a system of rural electrification schemes implemented by CEFA since years. The connection to the
national grid will favour sustainability of the whole system while allowing an extension of the rural
areas served.

Cost Evaluation
The cost evaluation is conducted per gross categories of works, namely: Civil Works, Site mobilization,
Access road, Powerhouse and outlet, Intake, Penstock - supply and lying, Electric line and connection
to the grid, Electromechanical equipment. The cost of the works is evaluated on the base of a very
recent experience made by CEFA in Ikondo. The cost is evaluated under the assumption that project
works and services are contracted to professionals and contractors whether local or international.
Rev. 3.4 – 03/24/2014 Corresponding e-mail: [email protected]
14
Furthermore the summary of costs shown in Table 3 is prepared following the required scheme of a
Europe Aid grant, in particular contingencies and overhead are set at the required percent value and
an item ‘other costs and services’ has been included to take in account possible required ‘visibility
actions’, publications, financial services, etc. Part of the project cost, namely the connections to final
users (including LV lines) may be supported by a performance grant from REA and the feasibility study
may be supported by a matching grant from REA. In December 2013 CEFA made a request for this
support and the beginning of the feasibility study is foreseen in April 2014.
Table 3 Ninga SHPP - Estimated project cost
Financial Assessment
The following assumptions have been made:
Sale of excess energy - Price per kWh.
The implementation period may take 2 years or more. Under the assumptions that the HPP enters in
operation in 2017, the price per kWh payable by TANESCO is evaluated on the base of the actual
EWURA fixed price (174 TZS/kWh), increased by an annual percent equal to 1%. Consequently the
projection price to 2017 would be 182 TZS/kWh. For further evaluation we estimate an increase of 2%
per year.
Distribution to Villages – Price per kWh
In order to make its rural electrification interventions sustainable CEFA has always foreseen that users
connected to its distribution grids pay for the electricity consumed. Tariffs are determined keeping in
consideration both the power plant’s necessity of being sustainable and the local communities’
average level of income. Specific tariffs have been established for different consumer groups.
Currently users in different grid managed by CEFA are divided in: private households, economic

inflation and possible increases in running costs.

According CEFA’s experience, payments are collected on a monthly basis. CEFA’s payment collection
officer first of all goes to each user in order to read the consumption data reported on every user’s
meter. The collected data are then processed by a software that determines for each user the actual
monthly consumption and the resulting bill, which is calculated according to the consumer group the
user is registered in. The tariff scheme foresees for all the consumer groups a minimum monthly
payment of 3,000 TZS, even when users’ consumptions are particularly low. Electricity tariffs appear to
not be a problem for the households and private enterprises already connected to the grid. In fact,
since the beginning of operations, bill payment rates have been always 100%. This is mainly due to the
fact that the tariffs set throughout the years have always been particularly favorable and cheaper than
the ones applied by TANESCO.
In order to carry out a sound evaluation we assume that the prices of table 4 will be increased of 20%
at the commissioning date and that further on they undergo a rate of increase of 2% per year.
The mix of users for this project has been evaluated as follows:
Households 85%
Commercial 10%
Public Services 5%
On this basis an average tariff can be calculated.
In the following Table the proposed tariffs to the owned local grid and the price of the energy sold to
TANESCO are shown.
Table 5: Proposed tariffs and projections
For future collection of payments, taking in account the high number of connections, CEFA will likely
turn to a pre-paid system.

Economic analysis
The purpose is to determine whether or not the project can be economically viable. In case of non-
viability, a grant component has to be determined in order to make the project viable. A typical
financial model can be: 20% developer equity, a credit line (70/80% of the investment) from REA, loans
from commercial banks, grants from International donors (such as REA, European Commission, GVEP,
UNIDO, etc) and Performance grant from REA for the connections. The assumed criterion is a required
payback period (taking in account a certain discount rate for the own resources) of maximum 7 years
and/or an IRR of at least 15% at the 15th
year. As shown in next Table 6 the investment seems to be
very attractive, even without any grant component.

7. Conclusions
Expanding renewable energy access for rural communities in Africa is a challenging task. In most of the
cases, government investments and donor funds have proved to be insufficient to expand access to
modern energy services in rural areas in a sustainable manner.
Nevertheless, Rural Electrification is now a priority for the Government of Tanzania and for several
International donors (WB, UE, UNIDO, etc.) and for this reason some instruments to make this type of
projects financially viable were put in place. By taking advantage of these opportunities, the new
project of CEFA, the Ninga SHPP, will provide reliable and affordable electricity to about 2,000

households and small enterprises in 7 villages in the Njombe Region. Also the project will sell the
surplus to TANESCO, increasing the national availability of power and at the same time assuring the
financial sustainability of the system. A partnership between non-profit and for-profit actors was here
proposed in order to rapidly mobilize financial resources, expand energy access, enhance
empowerment of the local communities and meet national programmatic targets for electrification
and energy production.
To realize this ambitious project, CEFA has decided to adopt the above mentioned innovative
approach, both financially and operationally, believing that a partnership with a private actor is an
opportunity for increasing the action’s impact on the beneficiaries granting the future sustainability of
the project. At CEFA we are also convinced that the private partner can benefit from this relationship,
taking advantage of our deep knowledge of the country and the long experience of dealing with all
stakeholders involved.
