Doc. No.6400/ NVVN/RE/2019-04 NVVN Pre-feasibility Report for Proposed Gas Supply DATE: 13.08.2019 Infrastructure for Andaman & Nicobar Power Project REV. NO. : 0 Page 4of 18

of all forms of electrical power including surplus power from NTPC stations for sale to SEBs, Power Distribution Companies, other organizations and bulk power consumers etc., in and abroad. NVVN has also carried out the implementation of 1000 MW National Solar Mission (NSM) Phase-I scheme of as a Nodal Agency for selection of the Solar Power Projects and Long term PPAs for purchase of Solar power and PSAs for sale of bundled power to Discoms. NVVN has been carrying out sale of 733 MW Solar Bundled Power to 21 Discoms under NSM Phase I. In the Financial year 2017-18, NVVN had traded 17,278 Million Units (MUs) apart from Renewable Energy Certificates (RECs) equivalent to 104 MUs and Energy Saving Certificates equivalent to 7,45,826. NVVN is a profit making company and has been consistently paying dividend to NTPC. During a meeting held under the Chairmanship of Hon’ble Minister of State (I/C) for Power & New and Renewable Energy on 10.01.2018, in which UT of Andaman and Nicobar Administration, Ministry of Home Affairs (MHA), Central Electricity Authority (CEA), Ministry of New & Renewable Energy (MNRE), NTPC Ltd, NLC India Ltd, Petronet LNG Ltd, PGCIL, Solar Energy Corporation of India (SECI) participated, power related issues of Andaman & Nicobar (A&N) Islands were discussed and Hon. Minister stressed upon the need for finding Short Term and Long Term Power Solutions to meet the Energy Requirement of Andaman & Nicobar Islands. Subsequently, A&N Administration requested NTPC for installation of 55 MW Dual Fuel (Diesel and Liquefied Natural Gas (LNG)) based power project to meet the Long Term Power Solutions of Andaman & Nicobar Islands. Feasibility Report for a 55 MW Dual Fuel (Diesel and LNG) based power project has already been prepared by NTPC Limited and the project has been handed over to NVVN (A wholly owned subsidiary of NTPC) for implementation. Initially, it was envisaged that LNG required for the Power Project shall be met from M/s Petronet LNG Ltd (PLL)’s proposed LNG Terminal to be set up at Hope Town in Port Blair. However, subsequently, it was decided by GoI that the procurement of LNG shall also be done by NTPC and the fuel supplier would be identified through a Global tender. The gas supplier will decide the technology and capacity of gas infrastructure depending upon the techno-commercial viability. The possible technological options are discussed in the paragraph below. The present proposal is to establish a Gas supply Infrastructure with suitable technology to procure and supply the gas to the proposed Power Project at Hope Town. The Gas infrastructure and power project will be located adjacent to each other at Hope Town, Port Blair in A&N islands. The power project being developed by NVVN is envisaged to be commissioned during 2021-22. The Gas Supply Infrastructure for supply of gas by the party to be selected through global tender, is proposed to be commissioned by year 2022.

2.2 Need for the Project & Its Importance to the Country & Region Proposed Gas supply Infrastructure is a dedicated unit to supply Gas to proposed gas power project, which is being set-up to meet the power requirement of A&N Islands. The detailed analysis of demand supply gap and justification for the project is presented in section 2.3.

2.3 Demand Supply Gap in Power The power project (55 MW) is envisaged to meet the power demand of Andaman & Nicobar Islands. It is expected to start yielding benefits from 2021-22. Being disconnected from the mainland, the A&N Islands relies on isolated power generation, powered by the Diesel Generation Systems. The power generation and distribution system of Andaman and Nicobar islands is served by standalone systems and each island has its own generation & distribution system. The power requirement of Andaman & Nicobar Islands is met mainly from Government owned diesel generation units with balance power purchased from Independent Power Producers (IPP). Power Generation Portfolio: (Dec-2015) SL.No. Generation Installed Capacity (MW) Percentage 1. Diesel 99.20 90.64 2 Hydro 5.25 4.80 3. Solar 5 4.56 Total 109.45 MW

From the details of installed power plants in A&N Islands, it is observed that concentration of Diesel Power Plants (59 MW) is highest in South Andaman, where approximately 64 MW out of total base of 109.45 MW is installed.

Conclusion As per above demand & supply scenario analysis, the sales of electricity is projected to grow from 229 MU in FY15 to around 330 MU by FY19 at a CAGR of 10% with Peak demand expected to grow from around 58 MW to around 68 MW by FY19. Moreover, out of the 99.2 MW DG capacities, about 51.745 MW of DG capacities has already outlived their lives thereby making the effective available DG capacity as 47.465 MW.

In order to meet the increasing power demand (CAGR of 10%) of A&N Islands while reducing dependency on conventional diesel generation sets (DG Sets), the proposal for setting up of 55 MW Power Project, which would help in reducing the diesel consumption through cleaner and cheaper fuel (Gas as primary fuel) is justified.

To meet the fuel requirement of proposed power project, installation of a Gas supply infrastructure is mandatory and justified.

2.4 Employment Generation (Direct & Indirect) due to the Project Gas supply Infrastructure shall be a mechanised and automated plant, therefore, the direct opportunities for employment during operation phase are limited. However, due to increased availability of gas and power, the opportunities for self- employment and business activities shall increase. During the construction phase, skilled and unskilled people on daily average will be employed. Preference will be given to the local population during construction and operation phase of the project depending upon the skill, job requirement and capability. Several other indirect employment opportunities such as transport, business, vehicle drivers and attendants, workshops, grocery and retails, medical, etc. will be created in the surrounding areas.

3.0 Project Description: 3.1 Type of Project, Interlinked Project & Interdependent Project The Gas Infrastructure may be selected from any of the following Technological options like FSRU, FSU with Regasification on land, CNG, etc. which are briefly explained below: FSRU (Floating Storage Regasification Unit) - LNG will be brought in small ships from nearby bigger LNG Regasification Terminals like Kochi, Ennore etc., which will be unloaded to small size FSRU with regasification anchored near a Jetty at Hope Town, A&N islands. FSRU would re-gasify LNG and supply gas to the power plant through a pipeline. FSU (Floating Storage Unit) - LNG will be brought in small ships from nearby bigger LNG Regasification Terminals like Kochi, Ennore etc., which will be unloaded to small size FSU without regasification facility at Hope Town, A&N islands, berthed in the water near the power plant. LNG will be transferred from FSU to Onshore Regasification Unit, which will supply RLNG through a pipeline to the power plant.

CNG (Compressed Natural Gas) - High pressure CNG cascades be will shipped from nearby main land to a suitable port in Port Blair, A&N islands and then will be moved by road to the Power plant. In this case no EC is required.

Proposed 55 MW dual fuel (Gas & Diesel) based gas power project is the interdependent project on the Gas Supply Infrastructure.

3.4 Size & Magnitude of Operation The annual gas requirement is estimated at approx. 0.065 MMTPA of LNG/85 MMSCM RLNG Gas. Accordingly, the related gas infrastructure shall be designed. Total project cost for Gas Supply Infrastructure is estimated at Rs. 500 crores approx.

3.5 Project Description & Process Details In case of FSRU, LNG shall be transferred from LNG Carrier (LNGC) vessel to Floating Storage & Regasification Unit (FSRU) by means of cryogenic transfer arms connected to LNGC through the unloading manifolds on finger jetty. Two arms (duty + standby) will be provided for unloading flow rate of 800 m3/hr each on both side of finger jetty. These arms shall be provided with Emergency Release Coupling (ERC). The FSRU shall have a 7,500 m3 LNG storage capacity at 98% full condition. Three IMO Type-C tanks (2,500 m3 LNG working capacity each) are proposed to achieve the total capacity. Further, Boil-Off Gas (BOG) from the storage tanks shall be sent to the LP BOG compressor located in the regasification plant area. The boil off gas is compressed to be used for fuel gas for FSRU generators. A vapour return line from the BOG header back to the LNG carrier (LNGC) is incorporated. The vapour is transferred to LNGC by means of a vapour return arm. LNG offloaded from LNG Pumps is sent to LNG vaporizers for regasification in order to produce fuel gas to feed Power Plant, FSRU generator and other users. Other alternatives for Gas supply infrastructure are as below.

FSU (Floating Storage Unit) - LNG will be brought in small ships from nearby bigger LNG Regasification Terminals like Kochi, Ennore etc., which will be unloaded to small size FSU without regasification facility at Hope Town, A&N islands, berthed in the water near the power plant. LNG will be transferred from FSU to Onshore Regasification Unit, which will supply RLNG through a pipeline to the power plant.

CNG (Compressed Natural Gas) - High pressure CNG cascades be will shipped from nearby main land to a suitable port in Port Blair, A&N islands and then will be moved by road to the Power plant. In this case no EC is required.

3.6 Requirement of Raw Materials LNG (Liquefied Natural Gas) will be sourced from Kochi/Ennore or any other suitable LNG terminal. In case of FSRU, LNG shall be transferred from LNGC to FSRU by means of cryogenic transfer arms connected to LNGC through the unloading manifolds on finger jetty. High pressure CNG cascades be will shipped from nearby main land to

a suitable port in Port Blair, A&N islands and then will be moved by road to the Power plant.

3.7 Resource Optimization, Recycle & Reuse In case of FSRU, LNG offloaded from LNG Pumps is sent to LNG vaporizers for regasification in order to produce fuel gas to feed power plant, FSRU generator and other users. The boil off gas is compressed to be used for fuel gas for FSRU generators and power plant. A vapour return line from the BOG header back to the LNG carrier (LNGC) is incorporated. The vapour is transferred to LNGC by means of a vapour return arm. This line can be used as a vapour make-up for the LNGC cargo tanks in the event of insufficient boil-off gas. In case of FSU/CNG resource and fuel requirement will also be optimized.

3.8 Availability of Power During construction phase, power required will be generated by temporary DG sets. During operation phase, energy requirement shall be met through captive power units. Boiled off Gas (BOG) will be used as fuel for captive power generation using gas engines.

3.9 Quantity of Wastes to be Generated During Construction and operation stage domestic wastes will be disposed off through the local municipal authorities. A small quantity i.e. about 0.5 KL/year of hazardous oily waste will be generated from the proposed LNG facility during periodic maintenance.
