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

Managing the power load of a Las Vegas casino might seem a daunting task. MGM Resorts International, which operates several iconic properties on the city’s famous strip along with other hospitality and entertainment venues worldwide, took matters into its own hands a few years ago as it tried to control its energy costs and also […]

Creating a faster-than-real-time Energy Management System (EMS) is a huge challenge for the power industry. In order to be considered faster-than-real-time, the EMS must be capable of executing within a

Exports of liquefied natural gas (LNG) from the U.S. continue to rise, as the use of natural gas for power generation increases in countries such as China, South Korea, Japan, and Mexico. Data from the U.S. Department of Energy (DOE) shows that four U.S. LNG export facilities combined to ship 483 LNG cargoes in 2018, a […]

Eight years after Germany decided it would halt nuclear power production by 2022, the country that relied on lignite and hard coal for 38% of its generated power in 2018 will phase out coal by 2038 or earlier

In line with customer preferences, U.S. investor-owned electric companies are heavily invested in decarbonization and electrification, the Edison Electric Institute (EEI) told Wall Street analysts and bankers on Feb. 6. In its annual presentation to potential investors and industry observers, the trade association that represents U.S. investor-owned electric companies lamented a number of uncertainties affecting […]

Paul DeCotis, senior director in West Monroe Partners’ Energy and Utilities practice, was a guest on The POWER Podcast. West Monroe, in partnership with Greentech Media, conducted a survey of more than 1,700 utility customers, 140 utility executives and managers, and more than two dozen regulators in major markets across North America. Its findings were […]

Utility-sponsored energy-efficiency programs have always seemed like a contradiction to me. Obviously, power companies make money by selling electricity, so encouraging customers to install energy-efficient

Renewable energy sources increased their share of the UK’s electricity supply in 2018, with new wind farms and biomass plants helping renewables contribute a record 33% of the country’s power in the past year. Coal-fired units, meanwhile, saw a 25% drop in their output, with coal providing about 5% of the country’s total generation. The […]

The International Energy Agency (IEA) deemed growth and disruptions of the world’s power sector so significant to the future of energy, it dedicated—for the first time—a four-chapter “special focus”

Cheap natural gas and social pressure to reduce carbon emissions give gas-fired power plants and renewable energy resources a competitive advantage over traditional coal and nuclear generation. Energy storage

NV Energy plans to retire a 254-MW coal-fired unit in a power-constrained region of Nevada at the end of 2021, four years ahead of schedule. The company will instead purchase 1,001 MW from new solar photovoltaic projects equipped with 100 MW of long-term battery storage, effectively doubling its total renewable generation from 14% in 2017 […]

The accelerated retirement of coal-fired and nuclear generation by 2022 could adversely affect reliability in four regions, including in the East and over parts of the central U.S., the North American Electric Reliability Corp. (NERC) warned as it released findings from a “stress-test” scenario.  But the entity tasked with ensuring reliability and security of the […]

Despite increased resilience actions, extreme weather events due to climate change are projected to increasingly threaten the nation’s energy infrastructure, and create fuel availability and demand imbalances, the Trump administration’s sprawling climate report released on November 23 suggests.  The Fourth National Climate Assessment (NCA4) released by the Global Change Research Program (USGCRP) is clear in […]

The Tennessee Valley Authority (TVA) wants public input as it considers closing two of the utility’s historic coal-fired power plants: its Bull Run plant in Tennessee, and the last coal-fired unit at its Paradise plant in Kentucky. The Bull Run Fossil Plant, near Oak Ridge, has been the only single-generator coal plant in the TVA […]

To remain efficient and profitable, utilities must anticipate the ebb and flow of the market. That means companies must gain visibility into the generation and consumption of energy. With network-level
