Ereda has undertaken a project that aims to analyse the possibility of limiting the cost of the energy supply to a medium-sized industrial plant, with an installed capacity of over 26 MW, located in the south-west of Kazakhstan. The cost of electricity for its processes accounts for an important part of its production cost, achieving values in excess of 40%. The price of electricity in the country is
expected to rise over the coming years. In addition, the plant is now required to reduce CO2 emissions from its industrial activity, which is why a further cost arising from the acquisition of emissions rights is expected in future. The sequence and activities undertaken were as follows:
Estimate of the wind and solar resource by means of a numerical simulation. Ereda has its own computational cluster and uses the WRF model, one of the most widely-used in the scientific community and by meteorological services worldwide. These tools are used to carry out an estimate of the expected wind and solar resource at the site with a longterm projection. Its main characteristics are illustrated in the following graphs.
differentiated hourly tariffs. Seasonally the variation is not very significant, despite the existence of a high and a low consumption season. Read more…
