IBERSOL Sustainability Report 2018

ENVIRONMENTAL PERFORMANCE Contracting electricity As the electricity supply contract ended in January 2019, a survey of the energy wholesale markets was carried out throughout 2018, analysing the proposals for buying energy at a fixed price or an indexed price. In relation to the historic average electricity price evolution, the most fa- vourable energy purchasing price was in the first three months of each year. When deciding to buy energy at a fixed price, for 2019, considering the months of January to March, the average final price obtained was €62.90/MWh, which was substantially above the indexed tariffs. That is why we chose to buy electricity in the OMIE indexed market - a daily market, with the option to close the position in OMIP - futures market, when these values are favourable. According to the records, the average indexed market value had a fall in average price in February to €54.71/MWh, with a downward trend in the following months. That is why the energy contracts are being maintained in an indexed market. However, a reduction in the prices of futures is foreseen for 2019, 2020 and 2021, compared to the indexed prices, and combined with the network drop, it is possible to obtain a better average price in a fixed market. Efficiency of the facilities Linked to restructuring the facilities and subsequent expansion of Iber- sol group’s new facilities is an increasing concern about the efficiency of the buildings in the country. In 2018, new buildings were given an A+ energy efficiency rating, reflecting their high performance when as- sessing building and operational sustainability. Among the aspects with the highest performance, environmental burdens, thermal comfort and sustainable use are of particular note. 52
