DESCRIPTION OF THE PROJECT

The project for expansion of the existing gas storage facility Chiren consists of staged capacity increse of the gas storage facility ʹ higher stored gas volumes, higher pressures in the gas reservoir and reaching higher average daily withdrawal and injection flow rates. Two options of reaching maximum capacities are mainly under consideration:

EXPECTED BENEFITS

Security of Supply, Market integration, N-1 National, N-1 Regional (Central Eastern Europe, South Eastern Europe, Balkan Region), In this moment UGS Chiren covers mainly seasonal fluctuations in domestic consumption and ensures the security of supply. Additional stored volumes and higher withdrawal and injection rates will serve Bulgarian and regional gas markets (Greek, Romanian, Macedonian and Serbian) via the existing and the new interconnections - IBR, IGB, / ^ ĂŶĚ /d ͘ dŚĞ ĞdžƉĂŶƐŝŽŶ ŽĨ ƚŚĞ h'^ ƚŽŐĞƚŚĞƌ ǁŝƚŚ ƚŚĞ ƉůĂŶŶĞĚ ŐĂƐ ƉŝƉĞůŝŶĞ ƉƌŽũĞĐƚƐ ŝƐ ŽĨ ŚŝŐŚ ŝŵƉŽƌƚĂŶĐĞ ĨŽƌ ƚŚĞ ŝŵƉůĞŵĞŶƚĂƚŝŽŶ ŽĨ ƚŚĞ /ŶĨƌĂƐƚƌƵĐƚƵƌĞ ^ƚĂŶĚĂƌĚ EͲϭ ;ZĞŐƵůĂƚŝŽŶ lzh EŽ ϵϵϰͬϮϬϭϬ Ϳ͘
