GE Is Banking on Africa’s Burgeoning Power Market

Sub-Saharan Africa’s power generation capacity is projected to surge 4% annually through 2040, and its current energy mix—which is today dominated by hydro and coal—will likely be more diversified as interest rises in renewables such as solar and wind, General Electric (GE) said in a white paper surveying market opportunities in the region that it […]

Insights Into Siemens’ Stunning Gas and Power, Renewables Shakeup

In the days following its May 7 announcement that it will spin off its Gas and Power business, Siemens has fleshed out how and when the carveout will occur, laid out its reasons for lumping its energy businesses together, and put forth a market case for why a business separation may be a “win-win” situation […]

EIA: Gas, Renewables Outpacing Coal for Power Generation

The percentage of coal-fired generation in the U.S. electricity mix will continue to decline, the Energy Information Administration (EIA) said May 9, with gas-fired generation accounting for at least 40% of the nation’s power this summer and output from renewables continuing to rise. EIA’s latest Short-Term Energy Outlook (STEO) said coal-fired units will produce only […]

ERCOT Warns of Summer Emergency Conditions as Demand Continues to Soar

The Electric Reliability Council of Texas (ERCOT) has issued a fresh warning that continued “above-normal” growth in electric demand could require it to enter Energy Emergency Alert (EEA) status to maintain system reliability this summer.  As it released its final Seasonal Assessment of Resource Adequacy (SARA) for the upcoming summer season (June to September), a preliminary […]

UK Milestone: One Week Without Coal-Fired Generation

The UK has gone a week without using electricity from coal-fired generation, according to the National Grid Electricity System Operator (NGESO), which oversees the power network in England, Wales, and Scotland.

Clump Weights in Offshore Mooring Systems

Offshore moorings have a long tradition in the oil and gas industry. Even though most offshore mooring systems feature similar components, they differ a lot in design, depending on the bathymetries, the metocean data, and the design of the platform they support. But despite the wide range available in the market, the fast development of […]

Energy Storage Changes the Power Profile

The power grid is a pretty complex system. Electricity is generally produced on an as-needed basis. Generators ramp up and down based on demand. However, energy storage systems are beginning to change how
