	The timing of the project was good. Interest in the project spiked because of a difficult situation of the tea factories: High energy prices coincided with low margins in the tea sector. This created a high demand for energy audits, and made energy efficiency measures and solar energy financially very attractive. Another lesson learned is that regular training of the management staff is considered useful to continue the implementation of some measures. This is particularly true for measures that have a large behavioural (rather than technical or investment) angle.		The timing of the project was good.

 ====Project Achievements====
-The project demonstrates that energy savings and substitution of fossil energy at tea factories are possible and cost effective. During project implementation, the tea factories implemented the recommendations from the consultants of Renergy, Equator Solar and the GBE project team, leading to immediate energy savings. Drying the fuelwood before burning can save up to 30% in fuelwood use within the factories, as use of dry fuelwood makes the burning process more efficient. Additional fuelwood savings can be achieved through pre-heating the boilers as well as insulating the pipes to reduce energy losses and increase energy efficiency. This was already implemented or recommended by the project in all seven participating tea factories. The savings in fuel-wood reduce the costs of the drying process and thus contribute to improving the economic efficiency of the tea factory. Furthermore, an indirect contribution is made to reducing deforestation of the local forests. In addition, by the end of the project, four of the seven tea factories had committed to installing solar photovoltaics, another three were considering it.

[[File:Equator Solar team collecting data about tea processing from a factory worker.png|thumb|Equator Solar team collecting data about tea processing from a factory worker]]One of the recommendations from the project to the factories is the use of bank capacitors. These components moderate the quality of the electricity and increase the efficiency of the use of energy. Power quality is often a challenge in rural grids in developing countries and this solution is often overlooked. It is particularly beneficial if the factory consumes its own solar energy. It will lead to a better utilization of the solar energy and fewer outages. With it, the tea factories can cover an even higher proportion of their electricity needs through self-generated solar power. Triggered by the energy audits, five of the factories are looking into the issue or had already adjusted the functionality by the end of the project.
 Beyond the immediate savings, the tea factories gained insights on the process and benefits of ISO 50001 certification. Four of them were already equipped with some kind of energy management or plan to implement it now. The very effective outreach strategy of the project led to an involvement of important stakeholders that served to disseminate the results. Beyond the MEMD, these include associations from the industrial and rural sectors of Uganda, the Ministry of Agriculture, the National Forest Authority, and various interested media parties. This forms a good basis for a larger scale replication.

 ==== Lessons Learned ====
-The project demonstrated the importance of approaching rural enterprises in Africa on-site and supporting them directly. Practical, hands-on approaches and deep analysis of specific situations were found to be beneficial. The tea factories commented that they saw the partnerships with technical experts and the access to expertise from Germany as valuable. Strong implementing partners with professional staff were also ultimately responsible for the impressive success and progress reached. The challenge of financing could be mitigated by the project through putting factories in touch with financiers. This is a persistent lesson of renewable energy projects and should be integrated in all comparable projects, also for commerce and industry, as it was done here.

The lesson is that energy efficiency is not only a technical challenge but can only be achieved through constant information exchange. It was clear that the policy framework needed improvement. In taking the policy makers to the field, they could gain a new perspective in the direct dialogue with the factory and the consultant. This helped inform policy makers and potentially has shaped the government’s support for further market development.

 ==== Sustainability of the Intervention ====
-The excellent communication strategy applied among project partners as well as with the political partners clearly contributed to the success, as the interviewees unanimously stated. But it also leads to the sustainability of the endeavour and continued market development. For instance, relevant national-level associations were present at the webinars. They will serve as multipliers and include the benefits of energy audits and sustainable energy investments into their messaging from now on, to foster continuity. Specifically, the Uganda Manufacturing Association (UMA), is committed to knowledge transfer. They are organizing webinars to inform larger audiences on energy audits and their potential for improved energy management and cost savings. The MEMD for its part, is working towards integrating energy efficiency through energy audits into its policy making. They are exploring appropriate policies and the necessary knowledge exchange between the economic actors involved. The project results contributed positively to the design of the new MEMD policy and accordingly to the sustainable use of the showcase results, as highlighted by several interviewees.

 Sustainability is also aided by the fact that several challenges are going to get less prominent with the increased introduction of energy management systems. For example, while the initial energy audits suffered from a lack of data on the energy performance of the equipment, this will be mitigated in the coming years, as the machinery is updated. Specifically, through energy monitoring in the context of the ISO 50001 certification, new opportunities for energy savings will be continuously brought to the attention of factory managers..

 =='''Project Approach'''==
-In Uganda, over a million people make a living with tea cultivation or work in one of the more than 25 tea factories in the country. But international competition and falling prices at the tea market in Mombasa put the Ugandan tea industry under pressure. Additionally, energy prices are rising. Tea processing is energy intensive as the various stages of tea production consume heat and power. Tea factories use electricity to drive fans and other machines and need heat for drying the tea leaves. Most of the factories were built in the 60s and 70s and the majority of them still use the older and inefficient machinery that was installed prior. This has led to higher energy costs, whereby energy costs constitute around 30% of the total tea processing costs.

But international competition and falling prices at the tea market in Mombasa put the Ugandan tea industry under pressure. Additionally, energy prices are rising. Tea processing is energy intensive as the various stages of tea production consume heat and power. Tea factories use electricity to drive fans and other machines and need heat for drying the tea leaves. Most of the factories were built in the 60s and 70s and the majority of them still use the older and inefficient machinery that was installed prior. This has led to higher energy costs, whereby energy costs constitute around 30% of the total tea processing costs.
 Tea factories rely on fuel wood to generate steam and heat for the drying process. Their demand for wood fuel is largely satisfied from eucalyptus plantations which provide a source of income for local farmers. Additionally, tea factories have high costs for electricity and diesel. In this context, the Green People’s Energy programme (Grüne Bürgerenergie, GBE) formed an integrated development partnership (iDPP) with Equator Solar Systems Ltd, a German-Ugandan company and Renergy Consulting, a German company, to identify ways to reduce energy costs of tea factories and make them greener. The iDPP is financed by equal contributions from GBE Uganda and the private sector partners (Renergy Consulting and Equator Solar Systems Ltd). Drawing on their speciality in sustainable energy solutions and advisory services, the two firms proposed to conduct site-specific energy audits for selected tea factories, accompanied by a number of outreach events, including webinars on energy management system as well as sustainable energy options which promote the solutions to the business community and policy makers nationwide.
