Megan Euston-Brown


Megan has a BA degree in Economics, English and History, with a postgraduate degree in African History from the University of Cape Town. Her work experience includes participatory research, policy development and development practice work in the land reform and rural development sector; freelance journalism and education materials development; and training, capacity building and project management in sustainable city energy planning and implementation.

Megan joined Sustainable Energy Africa in 2004. Megan Euston-Brown has worked in the area of sustainable energy development since 2003 and currently manages the City Energy Support Unit, a programme of Sustainable Energy Africa. The unit offers support to South African cities in their move towards clean energy development and reduced carbon footprints. This involves technical and process information in the areas of policy, and implementation, of energy efficiency, renewable energy deployment and energy poverty alleviation. A substantial focus of the work is on building the capacity of people to tackle these new and complex challenges. Megan has also worked within the region of Africa broadly, providing similar city GHG emissions inventory development and sustainable energy transition support. Megan is an experienced development facilitator and trainer and has worked extensively with local-level energy data collection and institutional development.

Yachika Reddy

Project Manager

Yachika has an MSc in Energy Studies from the University of Cape Town. She joined Sustainable Energy Africa in 2005. Her experience includes project management, training, facilitation, research and data analysis through working in wide-ranging and complex energy and climate change projects involving all three spheres of government (local, provincial and national). Working with the three spheres of government for more than a decade, she has a very good understanding of government’s priorities for development within these spheres. She has in-depth experience in local-level climate and energy data collation, analysis and strategy/policy development.

Zanie Cilliers

Project Manager

Zanie has BSc degree majoring in Environmental and Geographical Science, Ocean and Atmosphere Science, and Archaeology from the University of Cape Town, with a BSc (Hons) degree in Atmosphere Science.
She started working at Sustainable Energy Africa in 2008, after an internship in the City of Cape Town's Environmental Management Resource department.

Zanie's main focus areas include data collation and analysis, writing, greenhouse gas inventories and state of energy reports, and energy modelling, using programmes such as EnergyPlus and LEAP (Long-range Energy Alternatives Planning).

She has developed LEAP energy models at the individual metro level (such as Cape Town and eThekwini) as well as at the regional level (including a model encompassing the 27 municipalities in South Africa with the highest urbanisation level). Modelling outputs at the local level are used to advise the metros in their planning towards a sustainable energy future, while regional models highlight the emissions reduction contribution of urbanised areas in relation to the country.

Zanie has provided technical support to various African cities (Accra, Lagos, Addis Ababa, Tshwane, etc.) in collecting data on greenhouse gas emissions and reporting these emissions according to the Global Protocol for Community-Scale Greenhouse Gas Emissions (GPC). She received certification as an Urban Greenhouse Gas Inventory Specialist as part of the World Bank's City Climate Planner Certification Programme.

Simisha Pather-Elias

Project Manager

Simisha Pather-Elias joined SEA in March 2013 as a senior project coordinator.
She has two Master of Philosophy degrees. Her first MSc degree was attained in 2005 in Biotechnology from Rhodes
University following employment as a Scientific Officer at UCT in the Bioprocess Engineering Research Unit. There whilst working on several projects relating to environmental sustainability, her interest in energy and sustainable development was stimulated. In 2009 she pursued her second Master's degree in Energy and Development at the Energy Research Centre at UCT which she completed in 2011. Her research focused on a feasibility study for energy efficiency and renewable energy in the commercial sector.

After brief flirtations at Conservation South Africa, and the Botanical Society of South Africa, Simisha finally found her true home at SEA. Simisha constantly aims to balance her analytical and creative skills by being involved in several projects ranging from climate change mitigation and adaptation, energy and low-carbon modeling, policy and strategy development, and energy poverty in South Africa and Sub-Saharan Africa. She really enjoys working with bright and enthusiastic young minds and holds the graduate placement and mentoring at SEA.

Simisha is passionate about sustainable living, simplicity and tackling challenges in a holistic way. In her personal capacity, she assists in many community development and educational projects.

Tanaka Casandra Shumba

Project Manager

Tanaka joined Sustainable Energy Africa in 2018. She obtained a BSc and MSc in Chemical Engineering from the University of Cape Town.

Mark Borchers

Technical Expert

Mark has a B.Sc. in Civil Engineering and a M.Sc degree in Energy and Development Studies from the University of Cape Town's Engineering faculty. After working in the civil engineering industry, in 1988 he moved to the Energy for Development Research Centre (EDRC) at the University of Cape Town before co-founding the Energy & Development Group consultancy in 1993 and Sustainable Energy Africa in 2001.

Mark's work has been broad-ranging, from integrated energy planning for the South African government, impact assessment of electrification projects, promoting access to electricity in the SADC region, developing Botswana's energy policy, promoting the use of renewable energy and energy efficiency, sustainable building, and economic analyses of low income household energy options. Over the past decade he has increasingly been involved in developing Energy and Climate Change Strategies for cities around South Africa and Africa, and supporting the implementation of such strategies. SEA has pioneered a city-based approach to transforming a country's energy future.

Mark is a partner in the award-winning Green Building - the first "future normal" green office building in Cape Town. He firmly believes that an 8-hour workday is detrimental to personal wellbeing and society, not leaving adequate space for other critically important areas of life such as personal growth, leisure, family, exercise and community participation (the essay by Bertrand Russsel 'In Praise of Idleness' is informative in this regard). It tends to keep people behaving like sheep instead of being the architects of their own lives. Mark also considers the pursuit of wealth senseless, as it has been conclusively demonstrated that (beyond enough to meet basic needs) more wealth does not improve happiness, keeps people running on a treadmill to nowhere, and fuels the enormous and indefensible disparities of wealth that exist in the country and the world.
