6 1 Executive Summary The Indian economy presently is believed to have established itself on a healthy growth path and this would increase going forward the energy consumption in the country. This increase in consumption is expected to be supplemented by an alteration in the primary energy mix of India on account of the substitution of oil by natural gas. As per Vision 2030 Natural Gas Infrastructure in India Report by Industry Group for Petroleum & Natural Gas Regulatory Board, In future, the natural gas demand is all set to grow significantly at a CAGR of 6.8% from MMSCMD in to 746 MMSCMD in Currently the natural gas demand far exceeds domestic supply in India and the situation is likely to prevail in future as well. Given that there are very few new domestic sources available, additional demand is to be catered through RLNG. The natural gas deficit arising from the demand-supply mismatch is the potential that can be catered to by imported gas (i.e., regasified LNG). Southern region LNG demand deficit will be 19% in FY25 and 15% in FY35. Therefore, it is proposed to import liquefied natural gas (LNG) to Kakinada Deepwater Port and re-gasify it to meet the needs of GMR Energy Limited three power plants and other existing/ upcoming power plants and other industries would also benefit from the proposed LNG facility at Kakinada Port. With this, the project envisages to import 1.75 MTPA of LNG for the captive use of GEL power plants and the balance for other domestic users. The LNG facility is proposed to be developed at Berth 7 of KDWP. Berth 7 is already constructed and facilities required for LNG import need to be developed. At the ToR stage, two locations for regasification facility are being examined i.e. Location 1 being setting up regasification facility in the backup area available behind Berth 7 and Location 2 being setting up the regasification facility within the available land of GMR barge mounted power plant. Land required for development of LNG facility including regasification is ~48.1 acres in case of Location 1 and ~52 acres in case of Location 2. Considering location 2 as an eventual choice for regasification facility it would be necessary to lay on shore insulated cryogenic pipeline of ~3.2 km length. The LNG Carrier (LNGC) ranging in size from 80,000-90,000 m³ will be handled. The volumes of dredging would be limited to about 1.5 million cum considering the widening of the approach channel and turning circle. The construction and operation phase power requirement will be of the tune of 500 KW and 8 MW. The construction phase water requirement will be ~900 KL which will be sourced from existing supply of KDWP. Freshwater requirement during the operation phase of the project is 3.24 KLD and will be met through existing supply of KDWP. A sewage treatment plant (STP) of 2.5 KLD will be developed for treatment of sewage and reuse of treated wastewater will be carried out for irrigation of greenbelt and green areas. The estimated project cost for Location 1 is approximately INR 471 crores and Location 2 is INR 651 crores. Construction work will take around 6 months for development of 1.75 MTPA of LNG facility. The project envisages to generate direct employment of 72 and indirect employment of around Introduction GMR Holdings Private Limited (GHPL) and LNG Express India Pvt. Ltd. through their SPV are proposing to import LNG at Kakinada Deep Water Port (KDWP) in the state of Andhra Pradesh and supply LNG/RLNG to meet the demand of domestic customers. 1 Executive Summary Page 1

7 It is imperative to utilize the global softening of LNG prices for benefit/obligation of the industries meeting the emission norms using clean energy. Some of the industries are facing environmental concerns, Maintenance & Operational problems by using coal, rice husk, coal gas, biofuel bricks and other fuels. By bringing the LNG in to these above sectors, it will minimize and eliminate the above issues to a larger extent over a period of time thereby reducing greenhouse gases. GMR Energy Limited has been operating three power plants i.e. 220 MW barge mounted power plant near KDWP and 1138 MW gas based power plants at Vemagiri. Proposed LNG facility will cater gas requirements of the power plants to operate at optimum plant load. Additionally, it is envisaged that other existing and upcoming power plants would also benefit from the proposed LNG facility at Kakinada Port. 2.1 Project Background The Indian economy presently is believed to have established itself on a healthy growth path and this would increase going forward the energy consumption in the country. This increase in consumption is expected to be supplemented by an alteration in the primary energy mix of India on account of the substitution of oil by natural gas. The share of natural gas in the energy mix of India is expected to increase to 20% in 2025 as compared to 11% in 2010 (As per the Hydrocarbon Vision 2025 report). However, given that all the plans for expansion in natural gas supply in the country with the help of additional RLNG terminals, nationwide transmission pipeline network and transnational pipelines are expected to materialize by 2025, it is envisaged that the share of natural gas in the primary energy mix would reach 20% till 2030 if not more. In recent years the demand for natural gas in India has increased significantly due to its higher availability, development of transmission and distribution infrastructure, the savings from the usage of natural gas in place of alternate fuels, the environment friendly characteristics of natural gas as a fuel and the overall favourable economics of supplying gas at reasonable prices to end consumers. In future, the natural gas demand is all set to grow significantly at a CAGR of 6.8% from MMSCMD in to 746 MMSCMD in The supply of natural gas is likely to increase in future with the help of increase in domestic gas production and imported LNG. However, the expected increase in domestic production at present is significantly lower than earlier projections due to a steady reduction in gas output from the KG D6 field. Currently the natural gas demand far exceeds domestic supply in India and the situation is likely to prevail in future as well. Given that there are very few new domestic sources available, additional demand is to be catered through RLNG. Kakinada Deep Water Port is situated on East Coast of India (Latitude ' N Longitude 'E) which is an all-weather Port developed in a naturally sheltered bay called as Godavari Sand Spit (also called as Hope Island). Kakinada Bay, with water spread of about 2.5 sq.km is encircled and protected up to three quarters of its perimeter by the mainland and the "Hope Island". Hope Island had originated about 200 years ago from the mouth of the river littoral drift along the shoreline and had extended to a length about 11 nautical miles so far, thus forming into a natural breakwater protecting the entire eastern portion from the fury of the sea and providing tranquillity and shelter to the ships which are berthed at anchor in 1 Vision 2030 Natural Gas Infrastructure in India Report by Industry Group for Petroleum & Natural Gas Regulatory Board 2 Introduction Page 2

8 the Kakinada Bay. Thus, the Port of Kakinada has become one of the safest natural harbours on the East Coast of India. Kakinada Deep Water Port offers a very strategic location for development of LNG import handling facility and related infrastructure to meet the natural gas demand of the power plants and other domestic users in the region. The regasified LNG will be supplied to existing gas grid pipeline running parallel to Kakinada Port and some quantity of LNG in cryogenic state will also be transported to domestic customers using mobile tankers who are not connected through natural gas pipeline. 2.2 Need and Justification of the Project The Indian natural gas industry is relatively unseasoned, accounting for only 8 9% of the total energy consumption, while the world average is around 23.5%. In developed countries, the share of natural gas in the total energy basket is around 28 34%, while in other emerging countries like China, natural gas contribution to the total energy mix is as high as 33%. In India, consumption of natural gas has been steadily growing at 8.9% between 2001 and 2012 and is expected to grow further due to the advantages of lower costs and lower emissions. Natural gas consumption witnessed a steep year-on year increase of 21.5% at 56 Million Tonne Oil Equivalent (mtoe) in 2010 over 46 mtoe in 2009 and 25.5% year on year over 2008 owing to the cost-effective and cleaner nature of gas and the increased availability due to commencement of production from Reliance Industries Limited (RIL) in the Krishna- Godavari (KG) Basin. Natural gas is mainly consumed in the power generation and fertilizer industry, together accounting for 77% of the total consumption. The power sector consumption in 2010 was more than 45%. In the power sector, natural gas consumption grew by more than 69% in as compared to (Ministry of Petroleum and Natural Gas), which can be attributed to the increased allotment of gas from the KG Basin to power plants, following the commencement of production from the RIL KG Basin block. Other major users include the petrochemicals industry and the city gas distribution (CGD) network. While the domestic demand has been growing steadily, production has not grown on par to meet this demand, making way for LNG imports. LNG traffic through Indian ports has been growing rapidly over the past five years posting a CAGR of 14.8%. Demand for natural gas is also expected to grow given the higher level of overall economic activity in the country, lower volatility of gas prices as compared to liquid fuels, and rising environmental concerns, which increases the demand for cleaner fuels like gas. Power, fertilizer, and CGD sectors are expected to continue as the major consumer sectors of natural gas accounting for 86% of the natural gas demand. Growth in use of natural gas consumption in the country is expected to be driven by increased usage of gas in the above sectors and the growing demand from CGD. Based on the study conducted, the natural gas demand projections are given below: 2 Introduction Page 3

16 3.4 Analysis of Alternatives Scenario 1 Scenario 1 includes the mooring of LNG vessel of size to cum capacity with buoys to the west of Hope Island in open sea conditions for ship to ship (STS) operations. Thereafter, transportation of LNG by smaller shuttle tankers to LNG floating storage tanker stationed at the proposed jetty near the barge power plant site. In this scenario, Regasification facility is proposed in area adjacent to barge mounted power plant Scenario 2 Scenario 2 includes the mooring of LNG vessel of size to cum capacity with buoys to the west of Hope Island in open sea conditions for ship to ship (STS) operations. Thereafter, transportation of LNG by smaller shuttle tankers to LNG tanker stationed at berth number 7 of KDWP jetty. In this scenario, Re-gasification facility is proposed at area behind berth number 7 of KDWP Scenario 3 Scenario 3 includes berthing of LNG vessel of size to cum at Berth No. 7 of KDWP Port. The vessel will use the existing navigation channel of KDWP to reach Berth No. 7. In this scenario the regasification facility will be either behind Berth 7 or near barge mounted power plant Advantages of Selected Scenario Above three scenarios have been studied for the location of proposed LNG facility. Based on the following aspects, Scenario 3 has been finalised: LNG vessel will be berthing at Berth No.7 by using the existing navigation channel with some widening. Dredging requirement will be less and therefore disposal of material will also be less No disturbance to movement of fisher crafts because in Scenario 1 & 2 mooring of mother vessel and shuttle tanker movements will cause hindrance to fishing crafts. Construction activities are limited to development of LNG import facilities as Berth No. 7 is already available. Activity will be away from Hope Island and Eco-sensitive Zone of Coringa wildlife sanctuary No requirement of new navigation channel and turning circle for the feeder LNG shuttles Less number of vessel movements In case of Scenario 3, Boil off gas from the LNG Carrier can be completely recovered, pre-heated, compressed and utilized compared to scenario 1 and 2 where STS operations are planned. As water required for Hot water bath heater will be sourced from barge mounted power plant, therefore, cryogenic energy in LNG can be recovered to improve efficiency of barge mounted power plant and this will meet National cold conversion program from Government of India which inline is complied with and also meeting the requirements of OISD 194 (Part 4.9) 3 Project Description Page 11

17 4 Site Analysis 4.1 General The prevailing environmental parameters of the project site are essential to assess suitability of site and for planning. This chapter details the location of site, connectivity, existing features, meteorological conditions, oceanographic conditions, environmental aspects and other infrastructure. 4.2 Connectivity to Site KDWP is located on the Kakinada to Samalkot arterial road connecting to NH-5. Road connectivity from Kakinada is good and includes the National Highway 214 (NH-214) from Kathipudi to Ongole which also joins National Highway 16 (NH-16). Two state highways connect Kakinada to Rajahmundry. The nearest airport to Kakinada is at Rajahmundry, which is located approximately 65 km from the city, and has flight services to Chennai, Hyderabad and Vijayawada. The nearest major airport is at Visakhapatnam, which is at a distance of 145 km and has the services of many airline operators flying to major cities across the country and outside India. Kakinada is well connected by broad gauge railway to Hyderabad, Visakhapatnam and Chennai. Through a branch line, Kakinada is connected to Samalkot Junction (13 km) which is on the Chennai-Howrah trunk line, where most express trains stop and provide connectivity to Kakinada with major regional towns and cities. A railway connection exists at Kakinada Port Railway station. Connection to the deep water port has been taken at NFCL. A Reception and Dispatch yard and two spurs to the berths have been provided for facilitating movement of bulk cargo to the stacking yards behind the berths. 4.3 Topography The land near the coast, both at Kakinada Harbour and the area around the Bay of Kakinada is flat with sandy soil and with an average level of ~2.5 m above mean sea level. 4.4 Existing Land use Pattern Only 53% of 10 km radius is land area and the remaining 47% is Bay of Bengal. The table below presents the land use. Table 4: Landuse Pattern in the Study Area S. No. Landuse Area in Acres Percentage (%) 1 Hope Island Agricultural Land Settlements Plantations Industrial Area Mud Flats Barren Lands Water Bodies Salt Pans Forest (Mangroves) Dry water bodies Port Area Others Total Site Analysis Page 12

18 The land use distribution depicts about 33% is agricultural land and about 15% area is under plantations. Casuarina and cashew plantation are observed along the coast. 4.5 Existing Kakinada Deep Water Port Kakinada deep water port (KDWP) is located on the coast of Kakinada, Bay of Bengal in Andhra Pradesh. The geographical location of the Port is 16 58'35" N and '45" E. The port is naturally protected by Hope Island towards eastern side. Main Jetty has Six (06) berths and One (01) OSV berth. Total length of quay (7 berths) is ~1900 m and the length of OSV berth is 58m. The OSV Jetty has two finger jetties of 4 x 90m with berthing faces of 2 x 40 m. NRW extension with multipurpose berth of length 635 m (North)/ 150 m (South). The port has the navigation facilities i.e. navigation channel of length 10 km and channel of m depth, berthing area of depth m and turning circle diameter is 500 m. Liquid bulk imports include of POL products edible oil, phosphoric acid, sulphuric acid and ammonia. Dry bulk cargo imports include fertiliser raw material, coal, wood and pulp. Exports of cargo include iron ore, cement, clinker, white minerals such as bentonite, feldspar and general cargo like steel coils, billets, slabs, granites, grains, OSV rings etc. 4.6 Meteorological and Oceanographic Parameters Meteorological Conditions The climate in the area is tropical monsoon type. Wind patterns are governed by the SW & NE monsoons and transition periods between them, dividing the year into four seasons. The two transition periods, March-May (pre-monsoon / summer) and October-November (postmonsoon) are characterized by occurrence of Cyclonic storms, the latter period being more active. The South-West monsoon (June-September) is characterized by strong, persistent wind and rough seas. Majority of the annual rainfall in the region is during South-West monsoon (June-September). The general climatological condition as per recorded data at Kakinada is presented below: The highest recorded temperature is C (May-June) and lowest C (December) Relative humidity varies from 61% to 90% The average annual rainfall in Kakinada area is about 1115 mm ( mm). The highest recorded monthly rainfall is mm in October, 1994 The predominant wind direction during North-East monsoon is from North through East. Wind speeds greater than 30 kmph are for about 22% of the time, while the transitional periods are characterized by low speed variable winds, when there are no storms. The tropical depressions / cyclones in Bay of Bengal occur very frequent especially during post-monsoon season (October-November-December). Though occur rarely, the cyclones during pre-monsoon and SW monsoon are generally more intense in nature. The most severe storm effected the project region was in November 1996 which tracked across in the southern part with sustained wind speeds of 115 knots (59 m/s). The weather is hot and humid during most part of the year. The hottest part of the year is May & 1 st week of June with maximum temperatures around C. The coolest part of the year is January, with minimum temperatures around C. The project area gets most of the annual rainfall during southwest monsoon season (June-September) although a significant rainfall occurs during the northeast monsoon season from mid-october to mid- December. Tropical Depressions & Cyclones in the Bay of Bengal are frequent, few of which 4 Site Analysis Page 13

19 affect the project area. Prevailing winds in Kakinada are usually south westerly for most part of the year except during October to January when wind blows from northeast and east. Kakinada recorded an average annual rainfall between 1100 mm and 1150 mm in the last 10 years. The climatology of the area do not pose any constraint for the project apart from cyclones Oceanographic Conditions Bathymetry The bathymetry of the region is reduced to Chart Datum using predicted tides at Kakinada Port. The bathymetry inside the Hope Island varies from a minimum of 1.5m from Light House at Hope island and 1.8m at Southwest corner to a maximum depth of 15.7m from Kilometre Point (KP) The Main KDWP Inner channel is marked with depth ranging between 13.4 KP and KP and shoals up to either side of the channel with a general slope of approximately 1:25. The Main KDWP Outer Channel is marked with depths ranging between KP and 15.7 at KP and shoals up to either side of the channel with a general slope of approximately 1:22 except nearer to Hope Island region. Towards the Hope Island region between KP and KP 6.000, in the eastern side of the survey area, depth decreases to 1.5m with a slope of approximately 1:12. In the Main Berth and Turning circle area, the depth ranges between 11.2 and 14.5 m. Approach Basin is marked by the depth varying between 4.2m and 13m Geo-Technical Conditions Kakinada Deep Water Port had undertaken marine geotechnical investigations within the harbour area and the soil classification up to a depth of 8.5 m from the sea bed consist of very soft silty clay with traces of shell fragments and with low N values. The layer between 8.5 to 10m consist of silt with sand and clay particles and low to moderate SPT. Beyond 10m very stiff clay with moderate to high SPT is observed Tides Near Kakinada tides are semi-diurnal with a mean spring range of 1.3m and mean neap tidal range of 0.5m. The maximum current speeds are 0.4 m/s during spring tide and 0.15 m/s during neap tide. The tidal levels with respect to chart datum as reported in Naval Hydrographic Chart No are as follows: Mean High Water Spring m w.r.t CD Mean High Water Neap m w.r.t CD Mean Low Water Neap m w.r.t CD Mean Low Water Spring m w.r.t CD Mean Sea Level m w.r.t CD During October, the spring tide heights are notably higher reaching 2.0 m mainly due to persistent northeast winds. The above values clearly indicate that tidal variation is limited to 1.3m Currents The currents monitored during monsoon season in Kakinada bay, the maximum current speed at mid-depth was observed as 0.7 m/s. and the directions varies between northeast and southwest. The reported current values are within permissible limits for the project activities. 4 Site Analysis Page 14

20 Waves The rough sea conditions prevail during SW monsoon season with waves >2m height during 68% of time and also in NE monsoon season with waves >2m height for about 32% of time. These however do not affect Kakinada Bay area (project site), as it is protected by Hope Island from the east as well as south sides. The predominant offshore wave directions: During November March waves are predominantly from Northeast During March September waves from Southwest are predominant During October (transition period) waves from SW and from NE are equally common Significant wave heights during the NE monsoon vary between 0.2 m to 0.8 m and the corresponding wave periods vary between 5 and 7 seconds. These ranges in wave Height and period account for more than 90% of the observations indicating that waves during the NE monsoon are generally low. Significant wave heights during SW monsoon are slightly higher with heights between 0.4 m to 1.2 m, the corresponding wave periods 6 9 seconds. Long waves with periods between 9 and 11 seconds are also observed during both the monsoons and their percentage of occurrence is only 11% and 18% time during the NE and SW monsoons respectively. The near shore waves on annual basis are predominant in eastsoutheast directions. Based on the above wave data, it can be prima-facie concluded that tranquil conditions prevail in the basin for mooring and ship navigation Wind The average wind speed does not exceed 19 kmph for about 87% of time and the direction of wind varies with period of monsoon. In general wind speeds are stronger in the evening. Wind are mainly from NE (29.6%), SW (20.4%), E(15.8%) and S(11%) During south west monsoon, the wind speeds are weak averaging 1.5 m/sec and during NE monsoon, windare moderate to average (3m/sec). The land and sea breeze effect is characteristics to the NE monsoon causing the average wind speed to increase from m/sec at 8.00 hrs to m/sec at hrs. The direction is from landward during the day and seaward during the night Depression/Storms in Bay of Bengal The data on number of cyclones and depressions in Kakinada region for 80 years indicate the risk of severe cyclones is highest in may and june and from September till November. The number storms and depressions that have developed in the Bay of Bengal in the Kakinada region during is given below Table 5: Depression/Storms in Kakinada region ( ) S. No Month Storms Depressions Total 1 January February March April May Jine July August September October November December Total Site Analysis Page 15

21 It can be seen there from that a total of 83 storms and depressions have been observed near Kakinada during the above period of which 33 were cyclonic storms. During the cyclone of 1969, maximum wind speed exceeded 12 on the Beaufort scale and wave heights exceeded 5m outside Kakinada Bay. The sea level rise during the passage of the storm was reported to be 3.35 m, which is 1.86 above the normal spring tide level. Information on cyclonic storms are available in the E-Atlas for the period 1972 and 2007 Storm data from UNISYS for the period 2008 and Between 2008 and 2010, UNISYS shows only one storm during May 2010, and no depressions.

22 5.1 Layout of the LNG Facility The layout of the LNG facility at Kakinada Deep Water Port is given as FD0101. Land required for development of LNG facility including regasification is ~48.1 acres in case of Location 1 and ~52 acres in case of Location Vessel Characteristics It is proposed to handle LNG vessel of size to cum. The characteristics of 90,000 cum LNG vessel are given below: Table 7: Vessel Characteristics of cum S. No Parameter Dimensions 1. Length 240m 2. Breadth 40m 3. Draft 11.0m 4. Dead weight tonne Channel Requirements The existing navigation channel within Kakinada Deep Water Port has a bed width of 160 m with adequate side slopes. The navigational requirement as per PIANC guidelines stipulates channel width of 5 times the beam of design vessel. It is therefore necessary to take up navigation simulation study to ascertaining the widening of approach channel and the extent thereof. 5.4 Turning Circle The existing turning circle has a diameter of 500 m and considering the LOA of the design vessel as 240m. The turning circle requirement of LNGC is 480m which is twice the LOA of design vessel. 5.5 Dredging and Disposal The volumes of dredging are minimal and the extent would be limited to about 1.5 M cum considering the widening of the approach channel and turning circle. During the DPR stage the dredged disposal study would be undertaken by way of mathematical modelling analysis and the disposal area would be determined. The existing designated dumping area of KDWP would also be made use of. 5.6 Breasting/Mooring Dolphins The detailed project report would undertake the detailed analysis of the existing length of Berth 7 and by duly considering the safety radius as per OISD guidelines, determine the extension towards the south. The extension would be required for safe mooring of the vessel and suitable mooring dolphins with an approach platform would be developed. 5.7 Unloading Platforms As berth 7 is available and same will be used as unloading platform, only suitable number of unloading arms would be provided on the platform. 5 Planning Brief Page 17

23 5.8 LNG Storage LNG storage of 15,000 cum. will be installed at Berth 7. The LNG storage tank shall operate at slightly above atmospheric pressure and approximately at (-) 162 C. An additional storage of 1000 cum will be developed in case of development of regasification facility at barge mounted power plant. 5.9 Cryogenic Pipeline Considering Location 2 as an eventual choice for regasification facility it would be necessary to lay onshore cryogenic pipeline of ~3.2 km length Regasification Facility/Technology At Location 1 Fan Forced Ambient Air Regasification facility will be used. In this technology, multiple banks of fan forced ambient cryogenic vaporizers are used in parallel and serious combinations. Cryogenic LNG is fed into the inlet manifold system and distributed through banks of fan forced vaporizers. Fans on the top of the ambient vaporizers force down fresh ambient air from the top at all times and this provides required energy to re-gasify the LNG. Outlet temperature of RLNG remains 10 to 15 lower than ambient air. During the process moisture condenses surrounding the fins and after a few hours banks of vaporizers are interchanged and switched over for operations. The banks of vaporizers which have completed their duty go through a cycle of defrosting and after this cycle of defrosting they are ready for the next cycle LNG regasification operation. Interconnecting piping on inlet and outlet along with valves, instrumentation are provided for accurate distribution of LNG for re-gasification. Forced air circulation allows for accurate heat exchanger and also prevents excessive ice build-up around the heat exchanger fins. Shorter switching cycles also ensure that the ambient temperature surrounding the Regasification station remain closer to discharge temperature of gas. It is estimated that air temperature surrounding regasification station up to 10 Meters of distance, which will be well within boundary limits of the regasification station shall be approximately 15 to 20 below ambient depending on moderate wind condition and wind velocity At Location 2 A combination of Hot Water Bath Regasification system and Fan Forced Regasification System will be used. Hot water from the power plant is required to be cooled and also chilled for the process cooling requirement. In regular practice, cooling towers are used for cooling the hot water to a temperature near ambient temperature. For further reducing the water temperature, chillers are used. Since cryogenic energy is available in the form of LNG stored at -162 C, the process water will be cooled to the required temperature. This available differential temperature in the form of LNG is quite large, therefore it is possible to achieve very low temperature to obtain highest efficiency of cooling and power production. The system deploys a water bath made out of concrete construction in which all stainless steel heat exchanger is submerged along with required tabulators and agitators. Hot water from the power plant runs into the bath and cold water from the bath is sent back to the power plant. Stream of high pressure LNG is run through multiple passes through the heat exchangers and in the process LNG is regasified. Adequate number of temperature sensors, 5 Planning Brief Page 18

24 water level indicators and sensors, valves and gauges, etc. are installed on the equipment for the operating and safety requirements. Therefore from the concept development stage it is decided to recover cold from LNG in the form of cryogenic energy and utilize the same for process cooling for the barge mounted power plant, to improve the cooling efficiency covering the NCCD initiatives and OISD 194 (Part 4). Fan forced ambient air regasification system will be used to re-gas the balance quantity of LNG after utilizing the cryogenic energy at hot water bath Distribution Details The LNG and RLNG distribution details are provided in sections and and are shown in Figure 2 and Figure Utilities Power The construction phase power requirement will be of the tune of 500 KW and will be sourced from existing grid or KDWP power supply. During operation phase 8 MW of power will be met partly from existing grid and partly from power generators by using Boil off gas Water The construction phase water requirement will be ~900 KL which will be sourced from existing supply of KDWP. In case of Location 2 regasification facility, the water requirement for Hot Water Bath Regasification system will be 3280 m 3 /hr. This is a close loop water circulation system received from the barge mounted power plant and cooled water is supplied back to the power plant. Potable water requirement during the operation phase will be around 3.24 KLD and will be met through existing supply of KDWP Environment Management There is no waste water generation in the LNG Storage and Re-gasification system; however, during the process of fan forced re-gasification system there is clean water generation for which a collection and utilization plan will be prepared. This clean water is the result of moisture condensed, iced deiced and collected in the trench below the regasification station. Utilising of this clean water for potable use will be explored. Alternatively, this trench can be connected to storm water drainage if no use is envisaged. A sewage treatment plant (STP) of 2.5 KLD will be developed for treatment of sewage and reuse of treated wastewater will be carried out for irrigation of greenbelt and green areas HTL/LTL and CRZ Map The HTL/LTL and CRZ Map with proposed LNG facility is given as FD Resettlement and Rehabilitation Plan There will not be any land acquisition and hence no R&R Issues with the project development. 6 Resettlement and Rehabilitation Plan Page 19

25 7 Project Schedule and Cost Estimates 7.1 Project Implementation After obtaining necessary clearances from statutory authorities, the development of LNG facility will be completed within 6 months. 7.2 Cost Estimates The estimated project cost for Location 1 is approximately INR 471 crores and Location 2 is INR 651 crores. 8 Analysis of Proposal Demand for natural gas is also expected to grow given the higher level of overall economic activity in the country, lower volatility of gas prices as compared to liquid fuels, and rising environmental concerns, which increases the demand for cleaner fuels like gas. Power, fertilizer, and CGD sectors are expected to continue as the major consumer sectors of natural gas accounting for 86% of the natural gas demand. Growth in use of natural gas consumption in the country is expected to be driven by increased usage of gas in the above sectors and the growing demand from CGD. Presently the consumers who are connected through gas grid are getting benefits of natural gas. As laying a new pipeline to small scale industries is not a viable option, therefore, we propose to transport considerable volumes of LNG to all potential users in extremely safe conditions by road tankers. This enables use clean and environment friendly fuel at optimum level. Under this strategy, it is proposed to import liquefied natural gas (LNG) at Kakinada Deep Water Port and re-gasify it to meet the needs of GMR Energy Limited three power plants and other existing/upcoming power plants and other industries will benefit from the proposed LNG facility at Kakinada Port. 7 Project Schedule and Cost Estimates Page 20
