Hydro Tasmania Eyes Pumped Hydro To Shore Up Renewables

Monday, 13 August 2018

Chris Gwynne stands in a ravine below a towering dam in the Tasmanian wilderness and ponders whether the giant concrete structure can withstand the politics that may keep it from playing a key role in Australia’s clean energy future.

Is Climate Change or Negligence Responsible for Calif. Fires?

Monday, 13 August 2018

It was California’s biggest fire yet. In late July and August, wildfires devastated an area north of San Francisco far bigger than New York City, destroying more than 100 homes and injuring 2 fire fighters. It’s just one in a rash of fast-spreading blazes that have killed at least 56 people this year and last in the Golden State.

EIA: Solar, Wind Investment Flourishes, but Gas-fired Biggest Bargain

Tuesday, 07 August 2018

New wind and solar installations accounted for nearly 9,000 and 8,000 MW of capacity two years ago, respectively, while natural gas was close behind at more than 7,900 MW. The EIA used complete data from 2016 installations and will release 2017 generator cost data next year.

Negative Electricity Pricing Abounds As Wind, Solar Flood the Grid

Monday, 06 August 2018

Bright and breezy days are becoming a deeper nightmare for utilities struggling to earn a return on traditional power plants. With wind and solar farms sprouting up in more areas -- and their power getting priority to feed into the grid in many places -- the amount of electricity being generated is outstripping demand during certain hours of the day.

The Future of Energy Infrastructure in Africa

Utility experts flocked to Johannesburg last month and talked how the skies the limit for the future opportunities and challenges of grid expansion and modernization in Africa.

There's a Hidden Battery Play in the ‘Extremes’ of Power Prices

Tuesday, 31 July 2018

There’s an energy-storage opportunity hidden in plain sight -- and it has little to do with electric vehicles. As batteries go mainstream, the “deepest potential” for them is likely to be in arbitrage, according to a Bloomberg NEF report Tuesday.

China's Silk Road Fund Takes 24 Percent Stake in Concentrating Solar Power Plant

Tuesday, 24 July 2018

hina’s Silk Road Fund will acquire a 24.01 percent interest in the world’s largest single-site solar thermal plant, which is being built in the United Arab Emirates. The 700-megawatt project will be developed along with Dubai Electricity & Water Authority and Saudi Arabia’s ACWA Power Barka SAOG, ACWA said in a statement on Sunday. The plant will combine a central tower and parabolic trough technology to harvest energy from the sun, store it in molten salt and produce steam to generate power during the day and throughout the night.

Manufacturing Solar Modules with Solar Energy: One Company’s Vision

Monday, 23 July 2018

In July at Intersolar North America, Lee Zhenguo, President of LONGi Group laid out his “solar for solar” vision and explained how one day he believes solar will be so cheap that it will be used to help fix some of the monumental environmental issues that plague the world today.

Should California Opt-In to One Large Regional Power Grid?

Monday, 23 July 2018

Late last year, Renewable Energy World published articles and a video to explain the energy imbalance market to readers. This is the market that was created as a result of the fact that California often has excess solar, wind and hydropower and must “curtail” those energy sources, which means turn them off completely. Instead of curtailing them, through the energy imbalance market, those solar, wind, and hydropower plant owners can sell their power over the border to neighboring states.   Now the state is mulling an even larger opportunity, in which it would dissolve its current grid operator, the California ISO (Cal-ISO) and form one large regional grid, which would have oversight from the Federal Energy Regulatory Commission (FERC). The move could lead to lower electricity rates and cleaner energy for all regions, some say. Others worry that giving up state oversight and letting FERC take control could lead to California at some point propping up coal-fired power plants in Wyoming and Utah. After all, FERC has been considering proposals from Secretary Perry on how to keep coal and nuclear power plants alive — the latest move being one related to national security. The articles below outline some of the issues in play. What do you think the state should do? -- JMR
