Energy 4 Impact is a UK-registered non-profit organization which seeks to reduce poverty through accelerated access to energy. Our exclusive focus is on supporting off-grid energy businesses. Supported by a head office in London, about 80 of Energy 4 Impact’s 90 staff are based in sub-Saharan Africa, including Kenya, Tanzania, Uganda, Rwanda and Senegal.

Energy 4 Impact has operated in Africa for the past 10 years, and has worked with over 40 clients in the mini-grid sector, including micro-utilities and project developers using solar, hydro, biomass and renewable-diesel hybrid technologies. We have a 100-strong roster of active SME energy clients, about 30 of which are active in mini-grid and small IPP electrification models. In addition to supporting the SE4All Africa Hub’s Green Mini-Grid Market Development Program, Energy 4 Impact is engaged in three other mini-grid donor programs involving the World Bank (in Kenya and Tanzania), the IFC (in Tanzania), and SIDA (in Rwanda).

Energy 4 Impact provides advice on all stages of the mini-grid project development cycle including business model development, site selection, feasibility study support, regulatory approval, community engagement, demand assessment, supporting productive end use, cooperation with anchor customers, investor facilitation and negotiation, detailed system design, equipment procurement, construction, commissioning, and the operation and management of mini-grid systems and mini-grid utilities respectively. We advise and support developers on the process of raising capital from private equity firms, impact investors, banks, donors, and many others. We also have significant experience of and a well-developed approach for supporting the growth of productive use associated with mini-grid projects.

We deliver results. In the last five years, the growth of the 3000 businesses we supported resulted in 14.6 million people gaining better access to energy, over 9,000 jobs, and 12.2 million tonnes of CO2 abated. In the same time, the capital raised by those businesses during our support amounted to $90 million.

​INENSUS GmbH is a German consultancy firm for private sector driven mini-grid electrification and a leading engineering company for hybrid-power systems with medium to high renewable penetration in developing countries. INENSUS was founded in 2005 and is based at the “Energie-Forschungszentrum Niedersachsen (EFZN)” in Goslar in Germany. With its 9 highly specialized employees, INENSUS covers all mini-grid related subjects. The INENSUS micro-utility implementation experts have more than 10 years of experience in the mini-grid space and more than 5 years of experience in supporting other mini-grid developers to develop their business models.

For micro-utilities, INENSUS is a one-stop-shop providing everything required for successful mini-grid implementation and operation. Business models and technology designs provided by INENSUS go hand-in-hand. Inensus’ rural electrification division optimizes hybrid power systems economically and technically (component sizing as well as detailed technical design), identifies adequate sites, prepares financial models for mini-grids, adjusts or develops business and risk management models to local constraints and provides information required for company structuring and micro-utility establishment. INENSUS has experience of import/export of mini-grid components in many African countries.

Inensus’ technical division performs in-depth design of the system down to the parameterization level and can help prepare all system components for plug-and-play installation. In cases where off-the-shelf components cannot provide the functionality required, INENSUS designs customized system controls. All system designs are professionally documented with technical circuit diagrams, installation manuals and drawings.

The technical division and the system integration division of INENSUS has got a lot of experience implementing demand and load management strategies together with smart metering for pre-payment and partly also mobile money in mini-grids with different electricity customer structures. Load and demand management are especially important in renewable mini-grids to increase the utilization of renewable energy and therefore improve the profitability of the system. Furthermore, the team has expertise in electricity theft protection methods.

The INENSUS technical division installs and commissions power systems on site and conducts trainings for all stakeholders involved. The INENSUS mini-grid project implementation experts have experience in adjusting communication strategies to village structures (eg democratic versus strong man versus elder systems) and can also handle non-homogeneous social structures prevalent in trade centers of refugee camps. INENSUS has more than 6 years of experience in interacting and negotiating with African authorities like rural energy agencies, regulatory authorities and ministries all over the African continent.

INENSUS unique and comprehensive hands-on expertise in the mini-grid sector of Africa and Asia is much in demand by governments, international development organizations and impact investors. Policy makers and consultants in Senegal and Tanzania have consulted with INENSUS to design the local regulatory frameworks. In Nigeria INENSUS staff are directly supporting the Regulatory Commission to prepare a regulatory framework for the mini-grid sector. INENSUS staff frequently work for the Asian Development Bank on due diligence for mini-grid projects and provide support to local micro-utilities. INENSUS contributes to, or writes studies about, mini-grid electrification based on its experience and network in the sector as a paid advisor. UN organizations hire INENSUS staff for trainings in the renewable energy and off-grid electrification sector and its experts frequently serve as invited speakers at international rural electrification conferences. All these organizations engage INENSUS because of its micro-utility implementation experience.

INENSUS has been managing its Senegalese subsidiary ENERSA S.A. for more than six years and its Tanzanian subsidiary JUMEME Ltd. for more than one year. Both companies are mini-grid-utilities supplying electricity from wind-solar-diesel/solar hybrid power systems with battery storage. They both make use of demand and load management for customers in rural villages of Senegal and Tanzania respectively. INENSUS staff has been working on mini-grid and hybrid power system related projects in Senegal, Tanzania, Nigeria, Mozambique, Madagascar, Cameroon, Mali, Kenya, Uganda, South Sudan, Somalia, Namibia, Benin, Ghana and Tunisia.

INENSUS has developed a number of proprietary tools which may be used for the benefit of mini-grid developers engaged through GMG MDP. These include a demand assessment toolkit, a community engagement toolkit, a financial modelling toolkit and standard contracts between different stakeholders as well as a monitoring and evaluation toolkit. These tools are highly scalable and have been built on a four-year track record in Senegal. These tools are already available in versions that take account of political and socio-economic factors in several African countries (Senegal, Uganda, Tanzania), and the Philippines (ADB), and could be readily adapted for further countries.
