1Introduction
One of the main objectives of the Second Indonesia Power Transmission Development Project (IPTD2) is to strengthen and expand the capacity of the power transmission networks in Java-Bali and other large islands in East and West Indonesia. It involves upgrades and extensions to existing substations and, in some areas, new substations. IPTD2 is a follow-up operation of the on-going Indonesia Power Transmission Development Project (IPTD).
This EMP for Upgrades covers all subprojects under the IPTD2 that consist of an upgrade and / or extension to an existing substation. The EMP meets the requirements of the World Bank Environmental and Social Safeguards Frameworks for Category B projects.
1.1EMP Approach
This EMP for Upgrades covers a large number of small, discrete substation upgrade and / or extension subprojects, across five PLN Project Offices. This approach replaces a large number of repetitive and identical EMPs.
These projects have very small footprints, mostly within the boundaries of existing substations, and the severity and risk environmental and social impacts are low. The potential environmental and social issues of most of these subprojects are very similar (with few exceptions which will be separately addressed in the EMP). Furthermore, since all subcomponents will be owned by PLN, the EMP aspects of: institutional arrangements, occupational health and safety, and emergency preparedness and response systems are established by PLN corporate policy and will be the same for all of the subprojects.
The EMP contains standard mitigation and monitoring plans to cover typical impacts from upgrading equipment and installing new equipment at substations, including worker health and safety, earthworks and solid and hazardous waste management. The EMP also contains standard EMP monitoring, reporting and review processes to streamline processes across the Project Offices and the subprojects.
However, each subcomponent is unique in the sense that: (a) it is situated at its’ own unique location, (b) public consultations would involve different affected groups, and (c) the outcome of the public consultation may present special environmental or social issues. Therefore there is a screening process for each site to determine whether there are social and / or environmental risks beyond those covered in the standard mitigation and monitoring plans. Additional specific mitigation plans and monitoring plans have been developed for those sites with unique situations.
1.2EMP Structure
Project descriptions are located in the relevant Annex, along with any site specific mitigation and monitoring plans, as follows:
Annex 1 East Indonesia (Kalimantan) Project Office
Annex 2 East Indonesia (Sulawesi) Project Office

Annex 4 Sumatra I Project Office
Annex 5 Sumatra II Project Office
Standard mitigation and management plans, and standard approaches to consultation, EMP monitoring, supervision, reporting and review are included in the main document and Annexes.
PLN Project Offices can refer to their separate Annex to manage their specific work program, and refer to the main document for the standard implementation processes.
Section 9explains the review process for adding new projects into the EMP.

2Project Description
2.1Overview of IPTD2
Three components of the IPTD2 involve infrastructure investment and require safeguards instruments: 1) extension of 150kV substations in the Java-Bali system, 2) extension of 150kVand 70kV substations in East Indonesia, and 3) extension of 150kV substations in West Indonesia.
Component 1: Extension of 150kV Substations in the Java-Bali System
Under this component, selected existing 150/20 kV substations in Java-Bali will be expanded by adding one or more new transformers and associated equipment at each substation; replacing one or two existing transformers with new transformers and associated equipment with higher capacity; and constructingselected new150/20kV substations. These substations will be located across the islands of Java and Bali mostly in Jakarta, West Java & Banten, Central Java and Bali.
Component 2: Extension of 150kV and 70kV Substations in East Indonesia ($60M)
Under this component, selected 150/20 kV and70/20kV substations in East Indonesia[1] will be expanded by adding one or more new transformers and associated equipment at each substation or replacing one or two existing transformers with new transformers and associated equipment with higher capacity. In addition, selected new 150/20kV substations will be constructed. These substations will be located in Kalimantan (except West Kalimantan province) and Sulawesi.
Component 3: Extension of 150kV substations in West Indonesia ($102M)
Under this component, selected existing 150/20kV substations in West Indonesia[2] will be expanded by adding one or more new transformers and associated equipment at each substation or replacing one or two existing transformers with new transformers and associated equipment with higher capacity. In addition, selected new 150/20kV substations will be constructed. These substations will be located in Sumatra and West Kalimantan province.
2.2Upgrade and Expansion Subprojects
For upgrade and expansion subprojects, the key activities are to install new transformers and associated equipment or replace existing transformers and associated equipment with new ones with higher capacity in the existing 150/20 kV and 70/20kV substations. Upgradesdo not require land acquisition and will be implemented within the premises of these substations. While most of expansion subprojects do not require land acquisition, some subprojects will require limited additional pieces of land, which is normally adjacent to the existing substations.
3Potential Environmental and Social Impacts
The following is a summary of the key environmental and social impacts that may arise from any subproject. A full list of the standard potential environmental and social impacts is included in the Mitigation Plans. Site specific environmental and social impacts that are not included in the standard lists are included in Annexes 1 – 5 for the relevant subprojects.
