Retirement of baseload power plants, spurred by increasingly stringent environmental regulations, as well as a rise in cross-border electricity trade is making the task of ensuring gird stability and productivity ever more complex. Dynamic voltage control helps address such challenges, says Patrick Plas, HVDC and FACTS general manager at GE Grid Solutions.
Combustion-weighted carbon intensity of all fuels used to generate electricity in the United States is now lower than that of natural gas. After averaging near 60 kg CO2/MMBtu for decades, the carbon intensity in the electric power sector fell to 48 kg CO2/MMBtu in 2016 – slightly lower than that of natural gas, which produces 53 kg CO2/MMBtu.
Bob Kraft, the man at the helm of Powerphase has signed a Memorandum of Understanding (MoU) with executives of Indonesia’s state power company PT Perusahaan Listrik Negara (PLN) to cooperate on a phased roll-out of Turbophase Dry Air Injection in the country and wider Southeast Asia. The deal was signed in connection with the Indonesia visit of US Vice President Mike Pence.
The transition from fossil fuels to renewable energy sources is the most pressing challenge in the global energy industry, says Jantine Zwinkels, Consultant at Royal HaskoningDHV. Throwing in a word of caution, she added that “the challenge for our [renewable] industry is to stand truly on its own two feet and outcompete fossil fuels without public money.”
Amandi Energy, together with consortium partner GE, is preparing to start construction works for a 200MW power plant in Aboadze, Ghana. The facility's tri-fuel 9E.04 gas turbines will be initially fuelled by light crude oil, and later switched to run on indigenous gas, once supply from Ghana’s offshore Sankofa field will be available.
The electrical grid of tomorrow will require substantially more wind and solar power. Yet integrating intermittent renewable energy with energy-on-demand generation, as well as agile power T&D networks with energy storage, is “an engineering challenge”, says Dr. Steven Chu, who served as the 12th US Secretary of Energy.
MAN Diesel & Turbo has struck a contract with the Indonesian energy company PT Sumberdaya Sewatama to deliver and install four MAN 18V32/40 gensets for an industrial power plant (24MW). Once fully operational, the decentralised plant will generate electricity specifically for the Martabe Gold Mine, one Asia’s premier opencast mines.
The global gas insulated switchgear (GIS) market is forecast to grow from $5.23 billion in 2015 to $8.61 billion by 2020. According to GlobalData analysis, extensive power plant capacity additions in Asia-Pacific and the Middle East and the need to improve access to electricity are driving grid expansion and the GIS market.
Electricity will make up about 25% of final energy consumption by 2040, as estimated by the International Energy Agency (IEA) – a dynamic that drives GE’s Power Conversion business to design and develop electric consumer devices. Decarbonisation is, so far, mostly an issue for the power generation sector, less so for end-consumers of electric gadgets.
Jera, 50:50 joint venture of Tokyo Electric and Chubu Electric, is participating in a 1,000 MW combined-cycle power plant in New York state through its operating company Cricket Valley Energy Center. Start of commercial operation is slated for 2020.
Gas could be the “ideal partner for renewable energy generation” in a future sustainable energy mix, says Remi Eriksen, head of Det Norske Veritas (DNV) and Germanischer Lloyd (GL). He calls on the energy industry to work together to help policymakers, planners and the public understand and embrace the “non-price benefits of the fuel.”
Throughout the US, the running costs of solar-tracking photovoltaic units vary greatly dependent on the weather and how much the unit is exposed to the sun throughout the year. In Nevada and California, and other areas of the western United States which receive more direct solar radiation, single-axis PV panels track the sun’s path from east to west – a technology that is becoming increasingly cost-competitive with burning fossil fuels to generate electricity.
At Hannover Messe, running until the end of this week, Siemens is showcasing how a modular, hybrid power grid converter can work together with different decoupled DC sources. Sinacon HC, Siemens’ latest offering, links different power sources and batteries to the public grid or microgrids which allows for renewables integration and decentralised power.
GE Power and Marubeni have signed an agreement to deploy GE’s Predix-based digital solutions at its Nakasode Clean Power Plant, a 100MW combined-cycle unit, located in Sodegaura-city, Chiba Prefecture. Installation will start in April 2017 and full operation is slated to begin in March 2018.
Demand for natural gas from the US power generation sector is expected to flatline, if not slump, over the next five years, analysts say – provided that President Trump goes ahead with plans to scrap the Clean Power Plan (CPP).
