Energy NIS produces electrical and thermal energy from traditional and renewable resources and is engaged in the production and sale of compressed natural gas, procurement, sale and portfolio management of natural gas, trade of electrical energy, development and implementation of strategically important energy projects and energy efficiency projects. Since 2013 NIS has put into operation, on oil and gas fields, at eight locations in Serbia, mini power plants with a maximum power of 14.5 MWe. The environmental advantage of using these mini power plants is production of electrical and thermal energy from gas, which previously has not been used due to its high content of carbon dioxide and nitrogen, or because it could not be valorised due to the lack of gas infrastructure. NIS is also developing the electricity trade, and in addition to the Serbian market, it is present in the markets of Bosnia and Herzegovina, Montenegro, Romania, Slovenia and Hungary, and trades on the border with FYR Macedonia. In the following period, the key task in this business segment will be the construction of additional facilities to produce electricity, primarily the construction of CHHP at Pančevo Oil Refinery, which is realized in cooperation with Gazprom Energoholding.
