Hospital De S. Joao – the largest hospital in Northern Portugal and the second largest in the country – has installed a generation system from Cummins to ensure that its essential care is unaffected by power cuts.
The facility is on the edge of Porto and serves the inhabitants of the city and its neighbouring counties, who total about 3 million people.
To meet the increasing electrical needs of the 1124 bed facility, hospital officials selected a Cummins Power Generation system including new generators to provide emergency power to the entire establishment in the event of a power outage.
Cummins’ distributor in Portugal, Electro Central Vulcanizadora (ECV) fought off competition from companies including Caterpillar, to win the business. ECV worked closely with the main contractor, Teixeira Duarte Engenharia e Construcoes, S.A., to install the system, which consists of two C900 D5 generator sets powered by QST23 G3 engines.
To optimize power distribution, the equipment has been installed in a purpose-built underground room in the garden outside the main facility. Installing the C900 D5 generator set at a distance from the main buildings also minimizes noise and vibration in the hospital.
As the construction project progresses it is expected that a further two Cummins generator sets – C900 D5 and C350 D5 – will be added. The hospital’s maintenance department will manage the system, which will operate about 50 hours per year and during grid power outages. It will be tested without load every week and is capable of operating 24 hours a day.
As soon as a power blackout occurs, the standby system kicks in automatically with the generator being synchronized to produce full load power for all the buildings within the 15-second hospital specification requirement. Cummins’ solution will ensure that essential care is unaffected by any interruptions to mains power.
Russia initiates generation from coal bed methane with 1 MW J320 Jenbacher engine installed by GE
The first coal bed methane (CBM) to energy project in Russia has opened at Kuzbasskaya Energosetevaya Compania’s Talda site, near Kemerovo in southern central Russia.
The gas comes from test drills that Gazprom is conducting to capture the huge reserves of CBM in this traditional coal mining region. A Jenbacher gas engine from GE uses the gas to provide electricity, which is ultimately sold to the grid.
This project is part of a broader GE strategy to support environmental and energy efficiency goals. In addition, the aim of the Kemerovo administration is to encourage active coal mines in the region to collect the gas prior, during and after coaling operations to a larger extent. This not only will help to increase mine safety, but also will provide additional revenues to the coal mining companies.
“GE’s innovative technology allows us to turn a previously environmentally harmful gas into a safer, useful fuel to produce energy for our customers in a more cost-effective manner,” said Peter Kuruch, CEO of Kuzbasskaya Energosetevaya Compania.
“GE’s ability to install and start-up the engine in a short timeframe – 2.5 months – along with the company’s vast expertise in this industry were main reasons we chose them for this important project.”
A 1 MW J320 Jenbacher gas engine from GE powers this project. The contract was awarded in September 2010 to INTMA, GE’s official distributor and service partner in Russia for its Jenbacher products.
GE’s J320 gas engine technology has been successfully used in power projects from various types of coal seam gases (coal mine methane, abandoned mine methane and CBM) around the world. Currently GE has Jenbacher units with a total capacity of more than 400 MW running on this type of gas.
The engines have the potential to generate more than 3000 GWh of electricity per year, saving the equivalent of 830 million m3 of natural gas a year. CBM gas occurs naturally within coal deposits and is composed largely of methane, the principal component of natural gas.
CBM even burns a little more efficiently than natural gas, which could enable the gas to serve as a valuable alternative to natural gas on a global base.
The opening of the Kemerovo plant continues a series of actions by GE’s energy business over recent months aimed at growing its overall presence in the global coal mining and energy space in general.
Similar to this first-of-its-kind project in Russia, GE was recently awarded an order for one of its J420 units to power the first Kazakh Coal Mine Methane (CMM) project in the Arcelor Mittal Lenina Mine in Temirtau. The purpose of this project is to demonstrate the environmental, safety and economic benefits of CMM utilization to other mining operations in Kazakhstan.
This project was awarded through INTMA, which also operates as an engineering procurement company in Kazakhstan and in the CIS region.
