Bulgaria's TPP Maritsa Iztok 2 opens tender for gas desulfurization system upgrade

The upgraded system should have a recovery rate of at least 97%, the power plant operator said in a tender notice.

The deadline for submitting expressions of interest is November 26. Selected candidates are expected to be invited to submit offers of December 16.

TPP Maritsa Iztok 2 has eight operating units with a total installed capacity of 1,620 MW.

The power plant operator booked a net loss of 145 million levs in the first half of 2019, as its expenses for emission allowances amounted to over 192 million levs. 

The greenhouse gas emission allowances are part of the EU Emissions Trading System, which works on the “cap and trade” principle. Within the cap, companies receive or buy emission allowances which they can trade among themselves as needed. Each year companies must surrender enough allowances to cover all their emissions, otherwise fines are imposed.
