ENVIRONMENTAL MANAGEMENT PLAN

I Musfiq Substation

Replacement of Transformers

A. PROJECT DESCRIPTION – MUSFIQ SUBSTATION

The Azerbaijan Government has applied for funding from the International Bank for Reconstruction and Development (the World Bank) for a project to develop transmission system control and to rehabilitate power transmission facilities. Some of the funds are planned used for investments at this substation.

The Musfiq facility is located to the west of BakuCity on the periphery of the Greater Baku urban area. The substation is on quite steeply sloping ground directly above LakeCeyranbatan. There is no obvious sign of environmental damage to lands surrounding the substation. Site access is good and will pose no problems for equipment installation and evacuation.

Musfiq 220/110 kV substation is one of the five main substations in the Apsheron load centre area, west of Baku city. The station was placed in service in 1985/1986. It has connections to three 220 kV transmission lines, eight 110 kV lines and two 200 MVA autotransformers with a total combined rating of 400 MVA.

It is expected that load growth will maintain a high rate, considering the current development within the urban area serviced by the station. Moreover, the current loading conditions of the Mushfiq substation do not tolerate any maneuverability measures for the transformers. If for any reason one of the two transformers fails, Azerenerji will not be able to transfer the entire load on the second transformer. A load amounting to 120 MW will have to be shed.

Necessary rehabilitation / upgrading works subject of this EMP: Substitution of the existing transformers by two transformers rated 250 MVA each.

(Additional project work at the substation, but outside the scope of this EMP: Replacing the instrumentation and controls; and adaptation of the substation equipment for allowing installation of Remote Terminal Units for the SCADA/EMS system (transmission system control).)

The planned investment is expected to cost less than US$4 million.

II Imishli Substation

Replacement of Transformers

A. PROJECT DESCRIPTION – IMISHLI SUBSTATION

The Imishli substation is located some 1-2 kilometres from the urban area in relatively close proximity to a rail corridor. The access road to the site is surfaced and in fair condition but any heavy traffic will have to pass through much of the urban area. The site and surrounding areas are very flat but with no obvious high water table or contamination concerns. Agricultural land use adjacent to the site may have been intensive in the past but levels of activity are now low.

Imishli 330/230/110 kV substation is a principal switching station in the southern area of Azerbaijan, on the borders with Iran. It is the main connection point to the Iranian grid. The station was initially placed in service in 1984 (1 x 125 MVA transformer) and has been subsequently upgraded in 1994 and 2000 (1 x 125 MVA and 1 x 250 MVA respectively). The connection to the Iranian grid is at the 230 kV level. The substation has connections to two 330 kV transmission lines, one 230 kV line, six 110 kV lines, two 125 MVA autotransformers and one 250 MVA autotransformer with a total combined transformers rating of 500 MVA.

Currently, the loading of the 125 MVA transformers has reached a very critical limit (105 % at peak demand times). Imishli substation provides supply to a central railway power supply station, and growing industrial, agricultural and residential sectors in the area.

Necessary rehabilitation / upgrading works subject of this EMP: Substitution of the two existing 125 MVA transformers by two transformers rated 200 MVA each.

The planned investment is expected to cost less than US$4 million.

B. SCHEDULE – IMISHLI SUBSTATION

III Gandja Substation

Replacement of Transformers

A. PROJECT DESCRIPTION – GANDJA SUBSTATION

The Gandja substation is located 10 km to the south of Gandja city within a rural landscape. Access to the site is good and there are no obvious problems with ground condition.

Gandja 330/110 kV substation is a principal switching station in the eastern area of Azerbaijan. The station was initially placed in service in 1969 (1 x 125 MVA transformer) and has been subsequently upgraded in 1992 (1 x 200 MVA). The substation has connections to three 330 kV transmission lines, fifteen 110 kV lines, one 125 MVA autotransformers and one 200 MVA autotransformer with a total combined transformers rating of 325 MVA.

Currently, the loading of the 125 MVA transformers has reached a very critical limit (overloaded at peak demand). Considering that Gandja is the second biggest city, and the heavy industrial activities in this area, it is expected that load growth will continue. Moreover, this transformer has exceeded its operational lifetime.

Necessary rehabilitation / upgrading works subject of this EMP: Substitution of the existing 125 MVA transformers by a new transformers rated 200 MVA.

The planned investment is expected to cost less than US$2 million.

IV Yashma Substation

Replacement of Circuit Breakers

A. PROJECT DESCRIPTION – YASHMA SUBSTATION

The Yashma substation is located just north of the ApsheronPeninsula some 20 km north of SumqaitCity. It is an isolated complex set in an agricultural landscape in proximity to the main rail line between Baku and Russia and an associated, large rail yard. A small village is located approximately 1km from the site. The area is low lying within the coastal plain. The water table is obviously high, with all major facilities, road, and rail elevated on bunds or embankments. Adjacent lands are actively utilized for agriculture and are set well below built development levels.

Yashma 330/220/110 kV substation is a principal switching station north of the Apsheron peninsula. It is one of the two main stations on the connection link to the Russian grid. The station was initially placed in service in 1974 (1 x 200 MVA transformer) and has been subsequently upgraded in 1979 and 1983 (1 x 240 MVA and 1 x 200 MVA respectively). The substation has connections to two 330 kV transmission lines, one 220 kV line, nine 110 kV lines, two 200 MVA autotransformers and one 240 MVA autotransformer with a total combined transformers rating of 640 MVA.

V Qala Substation

Replacement of Transformers

A. PROJECT DESCRIPTION – QALA SUBSTATION

The substation is located on the southeast of the low-lying Apsheron peninsula, 25 kilometers to the east of BakuCity. It is an isolated facility set in a heavily degraded industrial landscape comprising an onshore oilfield and other individual, generally abandoned, industrial units. All built development in this area is on fill, and roads are placed on bunds suggesting high water tables. Widespread land contamination (predominantly oil) is evident in many areas in the vicinity of the site, but there is no evidence of contamination within the substation site or in its immediate proximity.

The substation was put in service in 1985. It has a single bus on the 110 kV voltage level with connections to six 110 kV transmission lines and two 40 MVA autotransformers with a total combined transformers rating of 80 MVA. The substation also has a number of switchgears at 35 kV & 6 kV voltage levels (9 cells on the 35 kV switchgear and 11 cells on the 6 kV switchgear).

The transformers are currently loaded at a critical limit. During winter, the transformers’ load reaches beyond 100%, and Azerenerji is forced to perform load-shedding maneuvers. It is expected that the load growth will continue at a high rate in this area. Qala substation provides power supply mainly to oil industries and to residential complexes.

Necessary rehabilitation / upgrading works subject of this EMP: Substitution of the existing 40 MVA transformers by a new transformer rated 63 MVA.

The planned investment is expected to cost less than US$1.5 million.
