Case study: Grid parity analysis of a PV-BESS hybrid

A proprietary technical and economic model was used to determine the optimal sizing of a grid-connected PV-BESS (solar PV and battery energy storage system) combination for a mine under development and located in the Northern Cape. This article presents the analysis of grid parity dynamics based on the levelised cost of electricity (LCOE) concept to […]

New nuclear build is justifiable, says WNA

  In a new report, Nuclear Power Economics and Project Structuring, the World Nuclear Association shows that new nuclear build can be justified in many countries on the strength of today’s economic criteria and identifies the key risks associated with a nuclear power project and how these may be managed to support a business case for nuclear investment. This is the executive summary of the […]

Study of the capital costs and the cost of electricity from new-nuclear in SA

  A new study by EE Publishers looks at the initial capital cost as well as the levelised cost of electricity (LCOE) generated by the proposed 9,6 GW new-nuclear build in South Africa. Note: Figures shown in RED were updated / corrected on 11 August 2016 at 21h30. The EE Publishers study estimates an initial […]

Understanding the cost of electricity from Medupi, Kusile and IPPs

  In order to understand and compare the cost of electricity from a power plant, whether it is coal-fired, nuclear, hydro, gas, wind or solar, one needs to look further than simply the capital, fuel or operating and maintenance costs in isolation, to a concept known as the “levelised cost of electricity” over the lifetime […]

Can South Africa afford new “carbon free” power stations?

  The editorial on the cost of carbon free new build power stations, which was published on page 3 in the June 2016 edition of Energize, elicited a wide response, and this is a more detailed version to demonstrate the source of the arguments. The core issue here is the cost of building new nuclear […]

Mike’s musings: When is a good time to retire?

  What sparked this month’s musing is an announcement that Eskom’s board has approved a new fleet renewal strategy based on economic viability instead of a purely age-based decommissioning of power stations, and has identified four of the oldest coal fired power stations as candidates for life extension, with a total capacity of 6,6 GW. […]

The true cost of storage

  When evaluating whether and what type of storage system they should install, many customers only look at the initial cost of the system – the first cost or cost per kilowatt-hour (kWh). Such thinking fails to account for other factors that impact overall system cost, known as the levelised cost of energy. The levelised […]
