Global resources of variable renewable energy—primarily wind and solar—despite breakneck growth over the past two decades, are beginning to run up against technological and policy limitations on further deployment, and future growth will depend on significant changes in policy and grid design, according to a new report. Released on September 20, Variable Renewable Energy Sources […]

A new assessment tool developed by engineers at Oregon State University (OSU) could allow people, agencies, and communities interested in developing small-scale hydropower plants in remote places to easily and accurately assess whether a potential project would meet their current and future energy needs. The free, open-source computer modeling package dubbed the Hydropower Potential Assessment […]

Ocean Power Technologies (OPT) deployed its first commercial PB3 PowerBuoy—a wave energy conversion system that incorporates energy storage—off the coast of New Jersey this July.

Development of the wave energy conversion technology for naval and civilian […]

Reliability and cybersecurity ranked as the two most important issues currently confronting the electric industry, according to surveys completed by 672 qualified utility, municipal, commercial, and community stakeholders for Black & Veatch’s “2016 Strategic Directions: Electric Industry Report.” It’s not particularly surprising to see reliability rank at the top of the list. “Reliability has always […]

The New York State Public Service Commission (PSC) approved New York’s Clean Energy Standard on August 1, likely saving three upstate nuclear power plants, while requiring 50% of the state’s electricity to come from renewable energy sources by 2030. Gov. Andrew Cuomo (D) praised the action in a statement following the announcement. “New York has […]

A severe water crisis gripping India this year has forced several of the country’s hydroelectric and thermal power plants to shut down. At least 10 of India’s 29 states have been stricken by severe drought after the monsoons failed for two seasons in a row (as of the start of July, the monsoons had still […]

The U.S., Mexico, and Canada today announced an unprecedented goal to procure 50% of North America’s total power generation from renewables, nuclear, carbon capture and storage (CCS), and energy efficiency technologies by 2025. President Obama, Prime Minister of Canada Justin Trudeau, and the President of Mexico Enrique Peña Nieto, announced the continental goal, part of […]

  The Environmental Protection Agency (EPA) has unveiled details of the Clean Energy Incentive Program (CEIP), a voluntary measure central to the judicially stalled Clean Power Plan that seeks to provide guidance to states and tribes that want to meet goals under the plan when it becomes effective. The final Clean Power Plan, finalized in […]

The Minnesota Public Utilities Commission (MPUC) approved Minnesota Power Co.’s integrated resource plan (IRP) on June 9, which calls for the economic idling of the company’s Taconite Harbor Energy Center—a two-unit 150-MW facility (Unit 3 was retired in June 2015)—this fall and ceasing coal operations at the site in 2020. The MPUC also adjusted the […]

China unveiled its 13th Five-Year Plan this March. The official proposal that will guide the country’s economic and social development from 2016 through 2020 lays out targets and other measures to address a number of climate change, air pollution, and water policies that will build on progress to transform its power sector. The plan sets […]

Droughts attributed to the El Niño phenomenon have gripped Venezuela’s neighbor Colombia. Bogotá in April prepared to ration power and instituted mandatory reductions in consumption, warning that

Oil-rich Venezuela is gripped by a power crisis so debilitating that the government has instituted four-hour daily blackouts across most of the country, forced hotels and malls to generate their own power, and

The world’s frenzied economic growth through 2040 won’t be matched by electricity demand growth, the Energy Information Administration (EIA) says in the International Energy Outlook 2016 (IEO2016 ) released on May 11. World net electricity generation will jump 69% by 2040, the IEO2016 reference case projects, but that is still well below “what it would […]

Hands down, 2015 was a record year for global investment in renewable energy. Excluding large hydroelectric projects, the amount of money committed to renewables rose 5%, to $285.9 billion, exceeding the previous record of $278.5 billion reached in 2011.

South Africa’s power system is preparing to receive a critical capacity boost. In March, state-owned utility Eskom grid-synchronized the first of four units of the Ingula Pumped Storage project in

The world added 33 GW of new hydropower capacity in 2015, including 2.5 GW of pumped storage, the International Hydropower Association (IHA) said in a recent brief. The new capacity made up only 3% of the

Upgrading automation systems can often extend the life of power generation facilities by decades while reducing downtime, improving operations, and reducing required maintenance. The Maggotty plant in Jamaica offers one such example. Many power generation facilities have equipment in good running order with many years or even decades of potential service life remaining, but operation […]
