Termoelektrarna Brestanica je po opravljenem celostnem energetskem pregledu družbe ugotovila, da je obstoječi kotel na energent zemeljski plin ali ekstra lahko kurilno olje moči 3,2 MW bil dotrajan, zastarel in z nizko energetsko učinkovitostjo. Prav tako je njegov vpliv na okolje bil prevelik, zaradi česar so bili primorani do konca leta 2019 opraviti sanacijo le tega. Tako so obstoječi kotel nadomestili z tremi novimi moči 600 kW (kondenzacijski kotel) in 2x 1400 kW (nizkotemperaturni kotel). V letu 2018 so stroški ogrevanja znašali 52.219,22 EUR, v primeru uporabe novih kotlov bi pa strošek znašal 40.640 EUR, kar predstavlja 11.579,07 EUR letnega prihranka. Vrednost investicije je znašala 879.628 EUR, kar pomeni, da bi se investicija povrnila v 75 letih. Investitor ima v prihodnosti, ko bo na podlagi dejanskih podatkov o porabi in stroških delovanja ogrevalnega sistema, namen natančneje izračunati prihranke, opraviti ponovno analizo, saj pričakuje, da bodo stroški ogrevanja na račun nove regulacije in krmiljenja še nižji od predvidenih, ki pa jih je trenutno nemogoče predvideti oz. oceniti. After completing a comprehensive energy audit of the company, the Brestanica thermal power plant found that the existing 3.2-MW steamblock, which runs on extra-light fuel oil or natural gas, was outdated and with low energy efficiency. Also, its environmental impact was too great, forcing them to remediate it by the end of 2019. Thus, the existing boiler was replaced with new 600 kW (condensing) and two 1400 kW (low temperature) boilers. In 2018, the cost of heating was EUR 52,219.22, and if new boilers were used the cost would be EUR 40,640, representing an annual savings of EUR 11,579.07. The value of the investment was EUR 879,628, which means that the investment would return in 75 years. In the future, when it will be possible to calculate the savings more precisely, the investor will carry out a re-analysis, where he expects the heating costs to be even lower at the expense of automation, which is currently difficult to estimate. |
