Workshops

Three pre-conference workshops will be held in Windhoek. Attendance at these workshops can be booked during the registration process, however attendance is limited so we would urge you to register and book as soon as possible to avoid disappointment.

Finance workshop

Monday 1 April

Hydropower is cost effective and can offer many additional benefits beyond power generation. However, projects are highly capital-intensive and site-specific, with a long preparation phase, lengthy construction period, and multiple environmental and social concerns. As a result, they are often regarded as risky investments, especially by private sector investors, making it difficult to attract financing for new projects. Yet hydro accounts for the largest share of renewable energy generation globally and will play a key role in facilitating the transition to a zero-carbon economy and improving energy access in emerging markets. It could also support the transition to a greater proportion of intermittent renewables through providing energy storage and grid stability services. The limited nature of public resources means that more
private sector financing will be needed in the future to facilitate this transition.

The University of Cambridge Institute for Sustainability Leadership (CISL) will present a workshop bringing together a diverse and knowledgeable group of financial stakeholders to discuss the role that the private sector may play in future investment in hydropower. In particular, we will review the risks and possible risk mitigation strategies.

Small hydro training workshop

Monday 1 April

The next in a highly successful series of small hydro training workshops will take place in Windhoek, prior to AFRICA 2019. The workshop is aimed at people who are, or will be, involved in hydropower development as part of rural electrification programmes. It will cover run-of-river hydro projects in the ‘pico’ range (1 kW to 1 MW capacity). As this is a diverse form of energy production, there are always areas which are unfamiliar to people, despite many individual special areas of expertise. Aspects to be covered include:

• analysis of scheme location and  definition of potential catchments;
• turning rainfall into an available flow range from a catchment and development of a flow duration curve
• power and energy generation calculation
• intake structures, channel and/or pipeline routes and sizing
• powerhouse design and equipment
• turbine selection
• generator, controls and switchgear
• grids, national and local.

This will be a ‘hands on’ workshop, which will involve participants, working in groups, to develop an actual hydro scheme during the day. The group will discuss the elements of the schemes, and this will follow through to final design

Reservoir and river yield workshop

Monday 1 April

In arid and semi-arid areas, where precipitation and runoff are highly variable resulting in long periods of drought, storage reservoirs are required to regulate river flows and to manage the negative impact on water supply. Many countries that face these challenges have long been involved with the development of practical methodologies to manage droughts, including the planning, design, operation and management of reservoirs and water supply systems. These methodologies may be diverse and vary in complexity and
sophistication but, essentially address one or more of the following basic aspects: the assessment of the water supply potential (or ‘yield’), the need for, and size of, regulation storage, the dam and system
operations, managing risk and planning for the possible impacts of climate change. The objective of the special session will be to present an introduction to these basic aspects, provide the opportunity for
sharing experiences and represent a first step to the establishment of guidelines for the assessment of reservoir and river yields in arid and semi-arid countries. The session will address: the concept of yield; modelling and yield determination; assessing the need for, and sizing of, regulation storage; risk-based planning and the role of stochastics; dam and water resources system operation; climate change; case studies. There will be supporting technical documentation.

Conference Programme

AFRICA 2019 will be the third international conference focusing on water storage and renewable energy development in Africa, co-hosted by Aqua~Media International and the International Commission on Large Dams.

The two main utilities, NamWater and NamPower, welcome international experts to come and exchange experience on key topics relating to water storage and renewable energy. Namibia has experienced a period of exceptional growth and economic stability (IMF Annual Report 2017), making it a prime destination for investments in the hydro sector.
