Today, the 20th anniversary of the launch of the last desulfurization coal block in Mělník will take place within the framework of the giant ecological project of the 1990s, when the first major revitalization of the Czech atmosphere took place after 1989.
Since the end of 1998, ZEZ has only operated factories that meet the strict emission limits of the Air Protection Act. The last desulfurized coal block under the giant ecological project of the 1990s was included in a trial operation on 12 November 1998 at the Mělník power plant. The second wave of isasiEZ coal resource modernization for more than 100 billion CZK was carried out in 2008-207. In selected power plants, investments are currently being made to reduce emissions in the framework of European boundary preparation starting in 2020.
During 1992 – 98, CEZ reduced power by 5,930 MW in coal-fired power plants and around 500 MW was equipped with modern liquid boilers. Sulfur dioxide and ash emissions have been reduced by at least 90% and nitrogen emissions by 50% thanks to technical measures. During the same period, CEZ also gradually closed the total power of 2020 MW at the oldest coal-fired power plant, replacing the Temelín power plant, whose inheritance was inherited after the state-owned Czech Power Plant division.
At seven years, the EZ electricity company realized perhaps the most extensive and the fastest ecological program in Europe (In Germany this process takes place twice). Under this program, a total of 28 desulfurizers and 7 fluid boilers were installed in the power plant, refurbished ash separator and power plant control system was improved. In total, 111 billion crowns were invested in modernization, desulfurization and other coal-fired power plants.
"Some people, see the green peaks of the Jizera Mountains and the Ore Mountains today, remembering how they were seen more than twenty years ago. After all, protests against air in northern Bohemia, even in November 1989, took over student protests at Narodni trida a few days ago, when people demonstrated at Teplice on November 11. Once again the wooded hillside could remind witnesses of how much work ČEZ had done, and not just him, and how he had significantly improved the environment in North Bohemia during the last twenty years, "said the director of the classical electric power engineering division and CEZ member. Ladislav Štěpánek.
Correction of past sins
The period before 1989 was characterized by energy policy as a cheap energy priority policy. But that has unfortunate consequences – wasting energy and irresistible environmental conditions. Already in 1986, the Comprehensive Energy and Ecological Program for the desulfurization and denitrification of the largest power plant in North Bohemia was established, but the appropriate smoke gas desulfurization technology to the east of the Iron Curtain was not available on the market. The loss of currency is valuable from the view of political representation from marginal affairs, a solution that can be delayed until later, it is unthinkable.
This solution to past debt has become a priority for the newly established ČEZ energy company. The new Aviation Act of 1991 stipulates that everything must be done at the end of 1998. First of all, a plan that is transparent, credible, and feasible needs to be prepared. In a short time it was not possible to make a replacement with truly new technology. Therefore, this program focuses on determining which power plants will be closed and which will be equipped with exhaust gas cleaning equipment.
The main problem is securing finance for such a large investment. In 1991, it was impossible to get tens of billions of crowns for the bank. But the project successfully involved the World Bank. By signing an ENERGY I loan in Washington in July 1992, CEZ became the first trading company in the former Eastern Bloc to obtain loans from the World Bank. It was a sign the bank with high international authority that CEZ was a trusted company that was able to fulfill its obligations. This supports the efforts of ČEZ to get most of its finances in its own name, without state guarantees. In 1994, ZEZ, once again the first block of the Eastern block, obtained a BBB rating from Standard & Poors and issued bonds in European capital markets.
