Financial benefits for SA from renewables exceed costs

first_img23 January 2014An independent study by the Council for Scientific and Industrial Research (CSIR) has found that renewable energy from South Africa’s first wind and solar (photovoltaic, or PV) projects brought R0.8-billion more financial benefits to the country than they cost during 2014.The benefits earned were two-fold. The first, derived from diesel and coal fuel cost savings, is pinned at R3.7-billion. This is because 2.2 TWh (terawatt-hours) of wind and solar energy replaced the electricity that would have otherwise been generated from diesel and coal (1.07 TWh from diesel-fired open-cycled gas turbines and 1.12 TWh from coal power stations).The second benefit of R1.6-billion is a saving to the economy derived from almost 120 hours of so-called “unserved energy” that were avoided thanks to the contribution of the wind and solar projects. During these hours the supply situation was so tight that some customers’ energy supply would have had to be curtailed (“unserved”) if it had not been for the renewables.Therefore, renewables contributed benefits of R5.3-billion in total (or R2.42 per kWh of renewable energy), while the tariff payments to independent power producers of the first wind and PV projects were only R4.5-billion (or R2.08 per kWh of renewable energy), leaving a net benefit of R0.8-billion.Dr Tobias Bischof-Niemz, who heads up the CSIR’s Energy Centre, explains: “The study was based on actual hourly production data for the different supply categories of the South African power system (e.g. coal, diesel, wind, PV). We’ve developed a methodology at the CSIR Energy Centre to determine whether at any given hour of the year renewables have replaced coal or diesel generators, or whether they have even prevented so-called unserved energy.”This CSIR methodology was fed with cost assumptions from publicly available sources, such as Eskom’s interim financial results from 2014 for coal and diesel costs, the Department of Energy’s publications on the average tariffs of the first renewables projects, and the Integrated Resource Plan on the cost of unserved energy.Because the study was an outside-in analysis of the system operations, conservative assumptions for the system effects and for the costs of coal were chosen. Given this, the actual cost savings that renewable energy sources brought during 2014 are presumably higher than shown by the study.“Our study shows that in 2014, renewable energy provided a net financial benefit to the country. Without the first solar and wind projects, we would have spent significant additional amounts on diesel, and energy would have had to be unserved during approximately 120 additional hours,” Bischof-Niemz says.“What is more, the cost per kilowatt hour of renewable energy for new projects is now well below R1 for solar PV and between 60c and 80c for wind projects. That will keep the net financial benefits of renewables positive, even in a future with a less constrained power system.”The CSIR intends to continue to monitor the fuel-saving and security-of-supply benefits of renewable energy.The agency undertakes directed and multidisciplinary research, technological innovation as well as industrial and scientific development to improve quality of life. In July 2014, the CSIR established an integrated energy research centre, which focuses on the key energy challenges of the country and the region and consolidates the energy-related research taking place across the CSIR.Source: CSIRlast_img read more

Tesla’s enhanced autopilot to arrive before New Year

That includes an automatic steering, lane change, parking, emergency braking, collision avoidance, and remote summon.Looks like we might be ready to rollout most of Autopilot functionality for HW2 towards the end of next week— Elon Musk (@elonmusk) December 23, 2016It doesn’t sound like a valuable add-on, but Tesla plans to add new functionality to the Enhanced Autopilot every month in 2017, while the original Autopilot is abandoned.Musk claims that the Autopilot neural net appears to be working well, but said company would need “a lot time to validate in a wide range of environments.” That testing should hopefully prevent another fatal accident, like the one in August.Tesla has a murky roadmap to full autonomy, which should come between 2018 and 2020. The next year, the electric vehicle supplier will begin adding more self-driving features to the Model S and X cars, bringing it to Level 3 or 4 autonomy.See Also: Would it make sense for Tesla to buy Lyft?At the same time, the company will start manufacturing the Model 3, an affordable electric vehicle for “the masses”. The Model 3 is expected to have an Enhanced Autopilot feature, again for $5,000, though it might be priced lower.In his “Master Plan, Part Deux,” Musk hinted at Tesla possibly launching a fleet of driverless taxis in major cities in the next few years. Ford has also hinted at doing this, leading some to believe the auto industry is moving from direct sale to lease or taxi services.
