Japan | Emergency Power

Emergency power provided a critical first step in recovery for a country devastated by the 2011 Tohoku-Chihou­Taiheiyo-Oki Earthquake and Tsunami.

Background

On March 11, 2011, a massive 9.0-magnitude earthquake – one of the five largest quakes in recorded history hit off the north eastern coasts of Japan. As  part of devastation, Tokyo Electric Power Company (TEPCO) had to take down several generators, and at least three nuclear reactors reported an explosion as a result of hydrogen build-up within their containment buildings. In total, TEPCO lost nearly 21GW of its total capacity. Power needs for rebuilding and disaster recovery were immediate, with little time for construction or setup.

Challenges

Access to supplemental power was not sufficient to meet demand, particularly in the cities of Hitachinaka and Yokosuka. Aftershocks, fire, and tsunami-related flooding continued to impact nuclear reactor sites beyond March 11, causing incidents in a total of 6 sites. Fears of radiation exposure fostered heightened scrutiny of nuclear reactor use, ultimately leading to the shutdown of all nuclear power. To make matters worse, two separate oil refineries were set ablaze by the earthquake, and the liquefied natural gas plant owned by the city suffered severe damage.

Solution

Following contract award from TEPCO, APR Energy installed a 203MW customized emergency power solution across two sites, Hitachinaka and Yokosuka. The solution consisted of gas turbines and diesel power modules, as well as all necessary transformers, consumables, mobilization to the port of entry, and supervision over electrical installation and fuel storage construction. APR Energy's turnkey approach included complete operational oversight and continued maintenance of the plant. A total of 69 generators were shipped from APR Energy hubs around the world, including five gas turbines that were air freighted for immediate availability. APR Energy's state-of-the-art technology and operational plan ensured alignment with Japan's stringent environmental requirements.

Outcome

By July 1, 2011-only days after the last delivery of equipment arrived on site by chartered vessel-both plants were set up and fully-operational, with the capacity to deliver up to 203MW of power to the TEPCO grid in order to alleviate load shedding and black outs. Due to the on-going nuclear energy concerns resulting in potential power shortages, coupled with peak demand throughout winter, TEPCO exercised the option to extend the contract at the Yokosuka site until 2013.
