On 18 September 2012, the Asian Development Bank (ADB) provided the Government of Sri Lanka (GoSL) with a loan of $130M to finance clean energy and network efficiency improvement focusing on the transmission and distribution projects to evacuate the power generated from renewable energy (wind and solar) parks/projects and to improve the overall network efficiency. The Ceylon Electricity Board (CEB) is the Executing Agency of the project. 2. As funded by ADB, the project was classified as category B on environment according to their Safeguard Policy Statement (SPS) 2009, which classifies projects based on its potential environmental impacts. An initial environmental examination (IEE) is required for category B project. An IEE was prepared for the project and was publicly disclosed to the ADB website in August 2012 as required by SPS 2009 and Public Communications Policy (PCP) 2011. However, during project implementation the previous lands earmarked for the substations became unavailable. Thus, this IEE, which has been posted to the ADB website in August 2012, was updated to cover some of the changes in the substation sites and the consequent changes in the length of some of the transmission lines resulting from the new substation locations. 3. The Clean Energy and Network Efficiency Improvement Project consists of transmission subprojects (Component A) and the distribution subprojects (Component B). This IEE covers Component A and consists of the following: A-I. Transmission System Strengthening in Mannar region A-1.1 Extension of 220 kV new Anuradhapura GSS A-I.2 Construction of 132 kV double circuit 55 km new Anuradhapura-Vavuniya Transmission line with 220 kV design for future upgrade of voltage A-I.3 Augmentation of Vavuniya GSS A-I.4 Construction of 132 kV double circuit Zebra 70 km Vavuniya-Mannar Transmission line with 220 kV design for future upgrade of voltage A-I.5 Construction of 220 kV/132 kV/33 kV Mannar GSS (1 x 31.5 MVA) A-II. New Polpitiya 220/132 kV grid substation (GSS) and associated transmission line A-II.1 Construction of 220/132 kV new Polpitiya GSS which is about 1.4 km away from the existing Polpitiya GSS A-II.2 Construction of 132 kV 1.4 km double circuit (2xZebra) Polpitiya-new Polpitiya transmission line A-II.3 Provision of 2x220 kV double bus transmission bays to connect the new Polpitiya to the new Galle 220 kV transmission line A-II.4 Construction of 220 kV 69 km, double circuit (2xZebra) new Polpitiya-Pannipitiya transmission line through Padukka to the existing Pannipitiya GSS A-II.5 Augmentation of Pannipitiya GSS (2x220 kV DB transmission line bays) A-III. Padukka 220/132/33 kV GSS and associated transmission line A-III.1 Construction of 220/132/33 kV Padukka Grid Substation A-III.2 Construction of 132 kV 8.4 km, double circuit (2xZebra) Athurugiriya to Padukka, transmission line A-III.3 Construction of 132 kV 12.5 km, double circuit (2xZebra) Athurugiriya to Kolonnawa transmission line A-IV. Construction of 132/33 kV GSS at Kegalle A-IV.1 Construction of 132/33 kV GSS at Kegalle IEE for Power Transmission Development Project Clean Energy and Network Efficiency Improvement Part 1: Conducting Due Diligence Implementing Agency - Ceylon Electricity Board 1 A-IV.2 Installation of 15 MVAr (3x5 MVAr) capacitor banks including 33 kV BSC bays at Kegalle 33 kV Bus Bar to control load PF A-IV.3 Construction of 132 kV 22.5 km, double circuit (Zebra) Thulhiriya to Kegalle transmission line A-IV. 4 Augmentation of Thulhiriya GSS with 2 nos. of 132 kV line bays A-V. Installation of reactive power compensation devices A-V.1 50 MVAr at Biyagama 33 kV BB (10x5 MVAr including BSC bays) A-V.2 50 MVAr at Sapugaskanda 33 kV BB (10x5 MVAr including BSC bays) A-V.3 30 MVAr at Kolonnawa-new 33 kV BB (6x5 MVAr including BSC bays) A-V.4 30 MVAr at Kolonawa-old 33 kV BB (6x5 MVAr including BSC bays) 4. The selected lands for new Politipitiya, Padukka and Kegalle GSS are all located in private rubber plantation and paddy, respectively. The Mannar GSS land belongs to the GoSL. Proposed land for Kegalle GSS will be purchased at market rates and acquisition of land will not be required from the surrounding communities. The initially proposed land for Mannar GSS belongs to the Irrigation Department, which had no objections in transferring the land to CEB. However, later Mannar District Secretary has verbally informed CEB in a meeting attended by DGM (Tr. Projects) and PM (CENEIP – P1) on 02/04/2013 that the said land is reserved for a proposed administrative building complex and therefore, cannot be released. Hence, CEB has sought other suitable lands. Presently, Land Commisioner’s Department has released the said land for construction of Mannar GSS and notified to CEB in their letter dated 04/11/2013. Accordingly, the original line route had been slightly deviated to connect to the new location, which has not caused significant change of length (less than 0.3 km). 5. The initially earmarked land for the new Polpitiya GSS was later found to be vulnerable to landslides after studies carried out by the National Building Research Organization (NBRO) and mentioned in their report in August 2013. Proposed remedial measures include heavy earth retaining structures and the GSS to be constructed in three levels, which will cause significant increase in cost. CEB looked out for suitable government land in the area, but being a hilly area Polpitiya is scarce of technically viable lands to construct a grid substation. Since no government owned lands were available with the relevant Divisional Secrataries, CEB has published a paper advertisement seeking a suitable private land. Selected land is a 6 ha out of the 20 has private land located much closer to the Polpitiya Hydro Power Station (1.4 km), and CEB is in the process of obtaining the possession of land. Due to the change of location of the new Polpitiya GSS, the length of 132 kV Polpitiya – new Polpitiya transmission line was changed to 1.4 km (against original length of 10 km), while the length of 220 kV new Polpitiya - Pannipitiya section became 69 km (against original length of 58.5 km).
