SA's energy supply shortage and what is being done about it
The South African electricity supply situation, which will remain under pressure for several years, offers a great opportunity for energy efficiency programme implementation. The presentation will provide an overview of the current electricity supply situation and the measures in place to deal with it over the short to medium term. Eskom's demand-side management programme will be covered in a fair degree of detail.

Industrial Energy Efficiency Improvement Project in South Africa
This project aims at capacity building in South Africa regarding energy management as well as optimization of pumps, compressed air, fans and process heating systems. It includes awareness seminars and training of end-users, vendors as well as experts. The presentation will also focus on the pump system component of the project.

Pumping system assessments in USA and how to apply them in SA
The UNIDO project in South Africa aims to train a group of experts on how to assess and optimize pumping systems. The assessments will be conducted according to the ASME EA-2-2009 assessment standard which will support the new ISO 50001 standard for Energy Management Systems. The assessment standard will be reviewed in detail.

Achieving sustainable energy savings in industry
The paper proposes a structured and holistic approach to energy management. It illustrates how changes made to a pumping system can affect the rest of the process, as well as how energy savings initiatives in the rest of the process can create more savings opportunities in the pumping system.

Identifying the best way to fund improvements to pumping systems
Updating a pumping system to operate more efficiently will save on operating costs but will incur capital expenditure - or will it?. This paper gives an overview of the financing options available in SA, both using and avoiding capex, and indicates which are most appropriate to differing company financial profiles.

Energy saving considerations for pump seals and systems
The selection of efficient ancillary equipment such as seals can provide large potential for overall energy savings and reductions in environmental damage. The paper also compares gas seals with equivalent wet seal technology and focuses on the environmental impact that pumping technology is having on legislation.

Assessment Standards - Gunnar Hovstadius (UNIDO International Expert)
ASME EA-2-2009 Energy Assessment Standard for Pumping Systems
Provides a common understanding of what
should be included in a pump system
assessment to replace the lack of a
standardization for pump systems previously
evaluated as part of an energy evaluation, audit,
survey or energy study.
Defines specific requirements that must be
performed for different assessment levels.
ASME EA-2G-2010 Guidance Document

should be included in a pump system assessment
to replace the lack of a standardization for
pump systems previously evaluated as part of an
energy evaluation, audit, survey or energy study.

Financing pumping systems improvements
Pumping systems are not low-cost items, so a company embarking on an improvement project is facing a potential financial nightmare! The Board is only too aware of this how does the Engineer or CFO present his case for an improvement project, particularly as it has to compete with a myriad of other more traditional Capex opportunities?
The good news is that the South African Government is keen to incent companies to save power through a series of schemes operated through Eskom and by 'carrot and stick' measures involving tax rebates and punitive tariffs. Overseas aid and local funding are also available in addition to banks and financial services companies offerings
The Workshop format will provide time to examine the pros and cons of each solution in more depth than was possible in the paper delivered at IPUC.
