Overview
Higashi Ogishima is a 2,000 MW gas-fired power plant in Japan, operated by Tokyo. It plays a key role in the country's energy grid as a large-scale thermal facility.
Higashi Ogishima is a gas-fired power plant located in Japan, with a substantial capacity of 2,000 MW. The facility is owned by Tokyo and is currently operational, contributing significantly to the region's electricity supply. As a gas power plant, it represents a key component of Japan's thermal power generation fleet. The plant operates under Japan's regulatory framework for thermal power generation, which includes emissions standards for SOx, NOx, and CO2. Gas-fired plants like Higashi Ogishima typically use combined cycle technology, offering higher efficiency and lower emissions compared to coal-fired units. The 2,000 MW capacity places it in the large-scale category for gas power plants in Japan. Higashi Ogishima's location in the Tokyo Bay area positions it to serve one of the world's largest metropolitan regions. The plant's output supports industrial, commercial, and residential demand in the Greater Tokyo Area. Its gas-fired technology aligns with Japan's efforts to balance energy security with environmental goals, as natural gas emits less CO2 per MWh than coal or oil.
Environmental context
The plant's gas-fired technology results in lower CO2, SOx, and NOx emissions per MWh compared to coal or oil plants. Its location in the Tokyo Bay area, a densely populated and industrialized region, means that air quality regulations are stringent. The facility's age and technology (likely combined cycle) influence its environmental footprint, with modern gas plants achieving high efficiency and reduced emissions.
Frequently asked questions
The Higashi Ogishima power plant is located in Japan, specifically in the Tokyo Bay area, with coordinates 35.4954 N, 139.7450 E.
The Higashi Ogishima power plant has a capacity of 2,000 MW, making it a large-scale gas-fired facility.
The Higashi Ogishima power plant is owned by Tokyo, a major utility company in Japan.
Gas power plants in Japan must comply with national emissions standards for SOx, NOx, and CO2, as well as local air quality regulations. The country also promotes high-efficiency combined cycle technology to reduce environmental impact.
Gas power generation typically emits about 50-60% less CO2 than coal per MWh, along with significantly lower SOx and NOx emissions. Modern combined cycle gas plants can achieve efficiencies over 60%, further reducing fuel consumption and emissions.
