 "markdown": "# Higashi Niigata LNG Terminal\n\nThe Higashi Niigata LNG Terminal is an LNG import terminal at the Niigata Base of Nihonkai LNG Co., Ltd. (日本海エル・エヌ・ジー株式会社) in Minato 1-chome, Seiro town, Kitakanbara district, Niigata Prefecture, Japan, serving the adjacent Higashi Niigata Thermal Power Station of Tohoku Electric Power and regional gas users.<sup>[1](https://www.bunka.go.jp/kindai/kenzoubutsu/research_doboku/denryoku/hatudensho/p004/index.html)</sup><sup> • </sup><sup>[2](https://eneken.ieej.or.jp/en/data/pdf/169.pdf)</sup>\n\n| Key fact | Detail |\n|---|---|\n| Location | Minato 1-chome, Seiro town, Kitakanbara district, Niigata Prefecture, on the East Port (Higashi-Ko) of Niigata Port<sup>[1](https://www.bunka.go.jp/kindai/kenzoubutsu/research_doboku/denryoku/hatudensho/p004/index.html)</sup> |\n| Operator | Nihonkai LNG Co., Ltd. (NIHONKAI LNG CO., LTD. in English), owned by Tohoku Electric Power, the Development Bank of Japan, Niigata Prefecture and others<sup>[3](https://www.nihonkai-lng.co.jp/company/index.html)</sup><sup> • </sup><sup>[4](https://www.tokyo-gas.co.jp/IR/library/pdf/investor/ig15total.pdf)</sup> |\n| Start-up | 1984<sup>[2](https://eneken.ieej.or.jp/en/data/pdf/169.pdf)</sup> |\n| Storage capacity | 720,000 kl<sup>[2](https://eneken.ieej.or.jp/en/data/pdf/169.pdf)</sup> |\n| Delivery capacity | 40,000 m³ per day (2002 figure)<sup>[2](https://eneken.ieej.or.jp/en/data/pdf/169.pdf)</sup> |\n| Throughput | Rated at 4 million tonnes per year in a 2004 industry survey; listed at 8.9 Mtpa in the Global Energy Monitor tracker<sup>[5](https://eneken.ieej.or.jp/en/data/pdf/260.pdf)</sup><sup> • </sup><sup>[6](https://lngatlas.org/country/jp/)</sup> |\n| Main customer | Higashi Niigata Thermal Power Station, with LNG-fired combined cycle series of 1,210 MW (series 3) and 1,750 MW (series 4)<sup>[1](https://www.bunka.go.jp/kindai/kenzoubutsu/research_doboku/denryoku/hatudensho/p004/index.html)</sup> |\n\n## Ownership and purpose\n\nNihonkai LNG was established in August 1978 to import liquefied natural gas through Niigata. [Tohoku Electric Power](https://www.edgepedia.org/tohoku-electric-power) held only 42.3 percent of the votes, alongside Niigata Prefecture, a development bank, an oil explorer, and a gas utility, so the terminal became shared infrastructure supplying city gas feedstock and industrial cold energy rather than a single company's fuel store.<sup>[7](https://the-shashi.com/en/tse/9506/)</sup> A Tokyo Gas investor survey likewise lists the owner as Nihonkai LNG (Tohoku Electric Power, Development Bank of Japan, Niigata Prefecture, etc.).<sup>[4](https://www.tokyo-gas.co.jp/IR/library/pdf/investor/ig15total.pdf)</sup>\n\n## Terminal and power station\n\nThe terminal began operation in 1984, the same year the first LNG-fired combined cycle series (3-1) of the Higashi Niigata Thermal Power Station entered commercial service; series 3-2 followed in 1985, series 4-1 in 1999, and series 4-2 in 2006.<sup>[2](https://eneken.ieej.or.jp/en/data/pdf/169.pdf)</sup><sup> • </sup><sup>[8](https://www.tohoku-epco.co.jp/news/normal/1219469_2558.html)</sup> The 4-2 series is a multi-shaft combined cycle plant in which two gas turbines burn LNG, two heat recovery boilers raise steam from the exhaust, and one steam turbine generates from that steam.<sup>[9](https://www.tohoku-epco.co.jp/whats/news/2006/12/20a1.html)</sup> Construction of the generating equipment was by [Mitsubishi Heavy Industries](https://www.edgepedia.org/mitsubishi-heavy-industries) and [Mitsubishi Electric](https://www.edgepedia.org/mitsubishi-electric), among others.<sup>[1](https://www.bunka.go.jp/kindai/kenzoubutsu/research_doboku/denryoku/hatudensho/p004/index.html)</sup>\n\nThe older Minato units at the same station, each 350,000 kW burning heavy oil and LNG, were placed in long-term planned suspension on March 31, 2021, as Tohoku Electric retired lower-efficiency aging plants while developing high-efficiency thermal capacity.<sup>[8](https://www.tohoku-epco.co.jp/news/normal/1219469_2558.html)</sup> In October 2020 the output of the 4-1 series was increased from 826,000 kW to 877,900 kW.<sup>[10](https://www.tohoku-epco.co.jp/ir/report/integrated_report/pdf/tohoku_report2020en.pdf)</sup>\n\n## Fuel supply and port context\n\nThe terminal receives LNG cargoes by ship. On February 22, 2011 it received the first cargo for Tohoku Electric from Indonesia's Tangguh LNG project in [West Papua](https://www.edgepedia.org/west-papua-province), about 64,000 tonnes, delivered by the 155,000 m³-class tanker Tangguh Foja.<sup>[11](https://www.tohoku-epco.co.jp/pastnews/normal/1182167_1049.html)</sup>\n\nThe terminal sits within Niigata Port's East Port industrial zone, which opened on November 19, 1969. The port as a whole now receives about 10 million tonnes of LNG per year and is described by the prefecture as the largest energy base on the [Sea of Japan](https://www.edgepedia.org/sea-of-japan) side of the country.<sup>[12](https://www.pref.niigata.lg.jp/sec/niigata_kouwan/1356786303810.html)</sup>\n\n## Scale in context\n\nWith 720,000 kl of storage, the terminal ranked among Japan's mid-sized LNG receiving facilities in the early 2000s: [Tokyo Gas](https://www.edgepedia.org/tokyo-gas) and Tokyo Electric's Sodegaura terminal held 2,660,000 kl and TEPCO's Futtsu terminal 860,000 kl, while smaller regional terminals such as Chita LNG (640,000 kl) and Kawagoe (480,000 kl) were comparable.<sup>[2](https://eneken.ieej.or.jp/en/data/pdf/169.pdf)</sup> Its 1984 start-up places it in the second wave of Japanese LNG terminals, after the [Tokyo Bay](https://www.edgepedia.org/tokyo-bay) terminals of the early 1970s and alongside other 1980s entrants such as Higashi Ogishima (1984) and Himeji II (1984).<sup>[5](https://eneken.ieej.or.jp/en/data/pdf/260.pdf)</sup>\n\n## References\n\n1.
