Suggestions to improve the mechanics of this tool

Long list

  1. Areas are not always drawing behind points, see for instance: oil price cost data
  2. Costs, cost sources and cost categories are not disappearing when deleted
  3. Draw lines between similar points in year graph
  4. Delete button
  5. Treat blank as zero
  6. Can we change the names of pages which will automatically update all links to the page? In particular it would be good to have consistency with the name of a wiki sector and the excel heading and also 'summary of ...' to be a little more succinct for technology cost graphs
  7. Axis on graphs sometimes fail to round giving x.000000001 on the y-axis
  8. Check whether no label means that can't have the same title with different years
  • when u enter a zero cost, say for opex, this is graphed to the left of the y axis in mid air. To get round this I have entered zero costs at a minimal ‘10’.
  • Reference scenario - suggest setting industry output to 2, otherwise if set at "1" (big increase in output) then the reference case includes a large cost of industry expansion without noting the benefits
  • Add /MtCO2 and /TCO2 units in capital cost input - For some sectors where our methodology makes cost a function of CO2 abated, such as CARBON STORAGE COST DATA, it would be useful to include this as a unit for inputting data. For most sectors we want to avoid people doing this, since it won't be directly comparable to the Calculator methodology but in a small number of cases we have had to make costs a function of CO2
  • Capital costs in /KWh bug - For some sectors it seems to calculate CAPEX if you input costs as a function of KWh (COMPRESSED AIR STORAGE COST DATA) but not for other sectors (BATTERY STORAGE COST DATA).
  • Comparing /KW to /KWh costs - Think this is a fault in the way of inputted the data: HYDRO PUMPED STORAGE COST DATA
  • Dealing with unknown operating costs - For a number of projects there are publicly available figures for building a large capital project (NUCLEAR POWER COST DATA) but ongoing operational costs are not published and presumably commercially sensitive. At present costs are not plotted on the CAPEX/OPEX graph without the OPEX cost being filled in. I'd suggest to automitcally add a dummy OPEX which is equal to the current OPEX range in the absence of information and flag that this isn't the original data. This will allow us to distinguish between cost sources that explicitly say no opex and those where the information is not available.
  • Energy saving measures costs - I've inputted energy saving costs in COMMERCIAL LIGHTING AND APPLIANCES COST DATA, this is equivalent to MARKAL Conservation measures. It allows me to enter the data but there might be a better way of presenting and entering the data (making sure our baseline is used). One suggestion could be adding energy conservation as a separate type of cost (in addition to technology and fuel). Also, to link with the technology packages approach to achieving energy reductions would be useful (see: X.b Commercial lighting, appliances, and catering Costs)
  • Valid in date - It would be good to distinguish between the year of the study and the year in which costs are forecast/predicted and over time to compare both variables. For many studies this is obvious when looking at the price year (except for MARKAL). Perhaps this is covered in the source in which case, is there a way of ensuring this information is collected i.e. the date of publication and linking it back to the cost data summaries?
  • UK/Abroad costs - To date, many of our costs are UK-specific but it is useful and interesting to compare international costs of delivering technology (Nuclear Power cost data). Clearly, wage costs and domestic supply chains may not make these costs directly comparable but we need to communicate this distinction. At the moment we do this through the label but we could add another box to capture this.
  • Axis bug - Adjusting the axis often crashes the cost data summary, this is probably where the unit is not recognised or is entered incorrectly
  • £(2011) We need to add a GDP deflator for 2011 prices, would suggest just assuming no deflator for now (until published figures) - therefore £(2011)=£(2010)

In progress


  1. Fix the layout in IE6
  2. Deal with numbers with commas, such as 1,000
  3. Make the charts cope when you set a scale in the millions
  4. Add an ability to clone data points
  5. When people type kW, always assume that they mean kWpeak
  6. It should cope with high-low ranges as well as low-high
  7. Add PJ as a unit in fuel and OPEX
