  • Dynapower Company has expanded the micro-grid system at its company headquarters in South Burlington, Vermont, by adding 375 kW/250 kWh of lithium-titanate batteries by Microvast Power Solutions. The micro-grid system has 100 kW each of PV and of wind power, and 750 kW of other battery storage. [Vermont Biz]

  • “The Value of Building-Scale Microgrids & Small Wind” Our energy landscape is changing, and there is no doubt of that. A lot of unpredictable factors will yet hit the playing field. One likely possibility that a lot of people in the industry are predicting, is that microgrids will play a much larger part than they do now. [CleanTechnica]

Friday, April 24:

  • Plans for a 25-MW floating offshore wind farm off the coast of Portugal have been given the green light by the European Commission. Aid approval was given for Portugal to provide feed in tariff payments to the 25-MW Windfloat project. The EC said subsidies would not distort competition in the single market. [Business Green]

  • Solar advocates pressed the Vermont Senate Finance Committee last week to alter the state’s net metering laws in order to allow larger projects to take advantage of better power pricing. Vermont limits the size of net-metered projects to 500 kW to encourage development of small installations. [Utility Dive]
  • Federal Energy Regulatory Commission’s latest Energy Infrastructure update reveals that wind, solar, geothermal and hydropower together provided over 75.43% of the 1,229 MW of new generating capacity placed into service during the first quarter of 2015. The balance, 302 MW, was natural gas. [RenewEconomy]
  • Germany’s cost of producing solar energy has shrunk to about a third of the price households pay. Most bids to build large ground-mounted solar plants in the first solar auction in Germany came in at €0.09/kWh ($0.097/kWh) to €0.10/kWh. German retail consumers are paying on average €0.298/kWh.

  • Opinion: “N.E. Governors Fixated on More Natural Gas” – New England’s governors agreed at a recent energy summit to work collaboratively on energy issues facing the region, principally by supporting the development of more natural-gas pipelines. The purpose of development is to keep the price of gas low. [ecoRI news]
  • Tucson Electric Power is seeking bids for the design and construction of a utility-scale energy storage system that would be operational by the end of 2016. The company, which has 414,000 customers, is seeking a project partner to build and own a 10-MW storage facility under a 10-year agreement. [Yahoo Finance UK]
  • Energy giant NTPC signed a power purchase agreement with distribution companies in the Indian state of Andhra Pradesh for 250 MW of solar power. The solar plant being developed under the first phase of the 1,000 MW ultra mega solar power project planned by the public sector major in the state. [The Hans India]

Graphs comparing additions of fossil fuels with those of renewables.

Graphs comparing additions of fossil fuels with those of renewables.

  • Clean energy has overtaken fossil fuels in terms of annual electricity generation capacity additions, with more renewable energy capacity now being added globally than coal + natural gas + oil combined. And, perhaps more importantly than that simple proclamation, there’s now no going back. [CleanTechnica]
  • According to an independent environmental monitoring firm, there were 695 “avian detections” and another 8 injured birds found over the first four seasons operation of the Ivanpah solar power tower project from October of 2013 (during the initial pre-production commissioning) and October of 2014. [CleanTechnica]
  • Under a new plan put forth by Maine’s Governor LePage, which is scheduled for a hearing Wednesday at 1 pm before the Legislature’s Energy, Utilities and Technology Committee, voters would no longer have a say on the creation of nuclear power plants with generating capacities of 500 MW or less.

Siemens hands over the world’s largest offshore grid connection to TenneT

Siemens hands over the world’s largest offshore grid connection to TenneT

  • Siemens has handed over the North Sea grid connection SylWin1 to German-Dutch transmission grid operator TenneT and it is now in commercial operation. The cable is more than 200 kilometres long and supplies up to 864 MW of green electricity, enough to power more than a million German households. [Renewable Energy Magazine]
  • Kyushu Electric, the Japanese utility that last year temporarily suspended new grid applications for large-scale solar, will install a huge battery project aimed at integrating a higher capacity for renewable power. The battery, to be installed in Fukuoka Prefecture, will have capacities of 50 MW and 300 MWh. [PV-Tech]
  • The Vermont town of Norwich is now the first community in the state whose municipal buildings all get their electricity from the sun, sending excess to the grid. A local solar manufacturer, Solaflect, arranged the financing with help of solar tax credits and the guarantee the town would continue to buy the power. [Rutland Herald]

Tuesday, April 28:

  • The US has taken another big step in the transition beyond coal to clean energy as the nation’s first offshore wind project broke ground. It is being installed off Block Island, 12 miles off the coast of Rhode Island. This project will provide 30 MW, enough for the island’s residents, cutting their electric bills 40%. [Huffington Post]
  • Chairman of the Carbon Trust and former chairman of Shell UK James Smith called on oil and gas companies to “change profoundly over the next couple of decades … if costly climate damage is to be avoided.” He said companies based on fossil fuels need to begin “tackling climate change” sooner, rather than later. [CleanTechnica]
  • An advanced flow battery system has been established at Randolph-Macon College in Ashland, Virginia. The system is from ViZn Energy Systems, based in Kalispell, Montana. The microgrid-scale system uses non-acid Zinc/Iron chemistry. ViZn batteries are made as 80-kW/160-kWh and 1-MW/3-MWh. [CleanTechnica]

Wednesday, April 29:

  • A tractor able to run on two renewable fuels, hydrogen and ammonia, was demonstrated in Iowa by its developers, who cited sustainability and zero carbon emissions. The tractor has a 150-hp engine and operates at full power for up to 4 hours, or up to 50 acres. [The Gazette: Eastern Iowa Breaking News and Headlines]
  • Grid-scale battery storage solutions have arrived in Europe, despite a lingering controversy. No longer a distant dream, projects in Germany are already feeding energy into the grid, while in the United Kingdom and Italy, commercial projects are close to coming online. The technology, however, is not fully tested. [Environment & Energy Publishing]
  • Hawaii lawmakers compromised for a bill that would set 2045 as the date to reach a goal of using renewable energy sources for 100% of the state’s electric power generation. House and Senate bills had different target dates for 100% renewable power. The state got 18% of its power from renewables in 2013. [Honolulu Star-Advertiser]
