Mitsubishi Power has completed its renovation of the Otake geothermal power plant in Oita Prefecture, Japan. The company worked under an EPC contract, together with Mitsubishi Power Industries and Mitsubishi Electric installing a new turbine increasing the plants capacity to 14.5 MW.

Mitsubishi Power, a major subsidiary of Mitsubishi Heavy Industries (MHI) Group, has today announced having completed its renovation of the Otake Geothermal Power Station (Kokonoe-machi, Oita Prefecture) operated by Kyushu Electric Power Company. Commercial operation of the renovated facility began in October 2020. The stable electric power supply generated by the highly efficient and reliable steam turbine installed as part of this renovation project will curb CO2 emissions, and contribute to a decarbonized economy.

This renovation project was conducted under an engineering, procurement and construction (EPC) contract by a joint venture comprising Mitsubishi Power, which supplied the steam turbine, Mitsubishi Power Industries Co., Ltd., which handled the supply and installation of auxiliary equipment, and Mitsubishi Electric Corporation, which supplied the generator and electrical facilities.

The power generation system utilizes a “double flash and dual pressure” method, the first of its type in Japan. This allows for stable operation of the steam well and efficient use of geothermal resources, and has increased the power output by two megawatts (MW) compared to the previous facility, to 14.5MW. Construction was completed two months ahead of schedule from the plan when work began in May 2019, allowing for the start of commercial operation in October.

In the double flash and dual pressure method, high pressure primary steam from a powerful production well, and low-pressure secondary steam from a weak production well, are supplied to the steam turbine. Steam is further obtained by lowering the pressure of the hot water extracted from the

Mitsubishi Power Completes Renovation of Generating Facilities at Otake Geothermal Power Station

YOKOHAMA, Japan, Oct 5, 2020 – (JCN Newswire) – Mitsubishi Power, a major subsidiary of Mitsubishi Heavy Industries (MHI) Group, has completed its renovation of the Otake Geothermal Power Station (Kokonoe-machi, Oita Prefecture) operated by Kyushu Electric Power Company.

Geothermal energy utilizes the heat energy of the magma chamber inside the earth, and because no combustion takes place above ground, little CO2 is emitted into the atmosphere, making it an effective method of power generation for

Cars burned down along Ono Road on Sunday afternoon, Sept. 27, 2020.

With little growth since Thursday night, firefighters were able to get more control lines around the Zogg Fire, the California Department of Forestry and Fire Protection reported Friday.

Only 101 structures are now under threat by the Zogg Fire, down from the 1,538 structures that were in peril at the blaze’s peak.

The fire, which started Sunday afternoon, is 56% contained after growing on Friday night to 56,168 acres — a gain of only 365 acres from Thursday night.

Cal Fire released the following new figures:

  • The number of structures destroyed rose to 170, up from the 153 reported Friday morning. The number of structures damaged rose to 23 from 21.

Also, power company PG&E announced that its crews have been rebuilding poles and power lines since Tuesday as they get access to more sections within the Zogg Fire evacuation and burn areas. 

Work to remove fire-damaged hazard trees and rebuild the electric infrastructure will continue through the weekend.

Much of the containment growth around the fire, as of Friday morning, happened in the south in the Highway 36 corridor in the area of Tehama County, Cal Fire said.

The north portion of the fire on Friday morning was still burning. It includes west of Clear Creek, according to a map released by Cal Fire on Friday morning. Firefighters, though, have managed to keep the fire from crossing the creek and into more populated areas west of Redding.

Cal Fire officials at their Friday press briefing announced that more residents

Bull of the Day:

Meritage Homes Corp.is perfectly situated to take advantage of the Millennial home buying rush. This Zacks Rank #1 (Strong Buy) is expected to grow its revenue by the double digits in both 2020 and 2021.

Meritage is the 7th largest public homebuilder in the United States. It has 300 communities across 9 states including Arizona, California, Colorado, Texas, Florida, Georgia, North Carolina, South Carolina and Tennessee.

It focuses on first-time and first move-up buyers.

Unprecedented Demand in July and August

On Sep 21, Meritage put out a business update on its first two months of the third quarter which included July and August.

It saw “unprecedented demand” in those two months and already sold more in just 2 months than it sold in the entire third quarter of last year.

Meritage also saw the strong demand continue into September.

In July and August, total orders jumped 73% year-over-year to 2,675 homes, up from 1,549 homes in the same period a year ago.

Average absorptions for those 2 months nearly doubled over the prior year to about 6 homes per month per community, net of 13% order cancellations in 2020 and 17% in 2019.

The company expects to close out some of its communities in late 2020 and early 2021 due to the strong demand so it’s on the hunt for new land positions so it can continue to grow its

Pacific Gas & Electric warned they may have to cut power to almost 100,000 homes in Northern California with strong winds and warm temperatures creating a risk of new wildfires. 

Company officials made the announcement on Friday, saying that ‘hot and dry conditions, combined with expected high wind gusts, pose an increased risk for damage to the electric system that has the potential to ignite fires in areas with dry vegetation.’ 

PG&E say power may be shut off to up to 97,000 customers in 16 counties between Sunday morning and Monday, according to The Los Angeles Times.

When heavy winds were predicted earlier this month, PG&E cut power to about 167,000 homes and businesses in central and Northern California in a more targeted approach after being criticized last year for acting too broadly when it blacked out 2 million customers to prevent fires.

PG&E equipment has sparked past large wildfires, including the 2018 fire that destroyed much of the Sierra foothills town of Paradise and killed 85 people.

This year, Northern California has been battling through the worst wildfire season on record. 

The North Complex Fire has torched more than 304,000 acres and is 78 percent contained. At least 15 people have died after being caught up in the inferno. 

The August Complex Fire has burned through a whopping 867,000 acres and is only 38 percent contained. One firefighter was killed while working to train and contain that blaze.

Wildfires aren’t the only reason why California residents have been experiencing deliberate power outages in recent months. 

Back in August, PG&E
