35% Of German Electricity Consumption Now From Renewables: Grid Challenges Ahead

Electricity generated from the sun, wind and other regenerative sources of energy accounted for 35 percent of Germany’s consumption in the first half of 2017. It was the first time that mark had been reached. The Centre for Solar Energy and Hydrogen Research in Baden-Württemberg (ZSW) and the German Association of Energy and Water Industries (BDEW) arrived at this figure in an initial assessment. Renewable energies’ share was thus up two percentage points from the previous year’s period.

Accounting for 39.4 billion kWh (kilowatt hours), onshore wind power was yet again the top source of green electricity (first half of 2016: 34.7 billion kWh, growth: 13.6 percent). Offshore wind power saw the steepest growth, increasing by 47.5 percent to 8.8 billion kWh (first half of 2016: 5.9 billion kWh). The amount of power sourced from biomass increased by 2.2 percent from 22.7 billion kWh to 23.2 billion kWh. Photovoltaic systems generated 21.9 billion kWh of electricity, an increase of 13.5 percent (first half of 2016: 19.3 billion kWh).

“Renewable energies’ increased contribution is gratifying. Unfortunately, the necessary grid expansion is not keeping pace with the growth in regenerative plants because of all the time lost to political debates. Grid expansion and the expansion of renewables have to be far more closely linked and better meshed to reduce the enormous costs of stabilizing networks. On top of that, we will not be able to do without conventional power plants as a backup for secure power supply,” said Stefan Kapferer, Chairman of BDEW’s General Executive Management Board, today in Berlin.

Prof. Frithjof Staiss, Managing Director of the ZSW, adds, “The good news from the electricity sector notwithstanding, the important thing is to continue developing the power supply as a whole in a reliable, affordable and environmentally sound way, and advancing the Energiewende [Germany’s exit from nuclear power and fossil fuels and transition to renewables] on the political and social fronts. And let’s not lose sight of energy efficiency as a core component. The math is simple enough: Energy that is not needed does not need to be generated.”

Hydroelectric power dropped by 18 percent to 9.4 billion kWh (11.5 billion kWh) and municipal solid waste (50 percent biogenic) was up 5 percent to 3.0 billion kWh (2.9 billion kWh), while geothermal energy dropped by 7 percent to 0.078 billion kWh (0.084 billion kWh).

MHI Vestas Signs Firm Order for Largest MW Project in Company History

MHI Vestas Offshore Wind will supply 90 of its flagship V164-9.5 MW turbines for the 860 MW Triton Knoll Offshore Wind Farm project; its largest MW project to date. MHI Vestas celebrated the financial close of the deal with innogy, at the site, confirming the project as the largest (MW) in the history of the turbine company. Affirming its strengthening position in the UK offshore wind market, the Danish-Japanese joint venture will supply 90 of the world’s most powerful commercially available turbine, the V164-9.5 MW, and has agreed on a comprehensive 5-year O&M agreement.

Renewables Provide 17.8% Of Total US Electricity. Solar Now 2.0% And Wind 6.0%

According to the latest issue of the U.S. Energy Information Administration’s (EIA) “Electric Power Monthly” report, U.S. electrical generation from renewable energy sources (i.e., biomass, geothermal, hydropower, solar – inc. distributed solar, wind) rose by 14.69% during the first three-quarters of 2017 compared to the same period in 2016. Simultaneously, electrical generation by fossil fuels and nuclear power combined declined by 5.41%. Nuclear power and coal both dropped by 1.5%, natural gas (including “other” gas) was down by 10.7%, and oil (i.e., petroleum liquids and petroleum coke) plunged by 17.1%.

IET’s Renewable Power Generation Conference Comes To Copenhagen

The Institution of Engineering and Technology’s popular Renewable Power Generation conference will be making its first visit to Denmark this year. The conference, now in its 7th iteration, will be hosted by the Center for Electric Power and Energy at DTU, which also manages the world-class experiment platform for research and development of renewables integration – PowerLabDK. Over 180 new research papers will be presented at the conference. Attendees will be able to find out the latest ideas and thinking around wind power plant modelling and control; wave and tidal energy; renewable energy forecasting; power conversion and grid interaction; Hybrid systems combining multiple energy sources; the impact of distributed generation and use of HVDC.

Ingeteam Develops New Optimal Offshore Power Conversion Architecture

Ingeteam, an independent global supplier of electrical conversion and turbine control equipment, has announced that a recent in-house R&D study allowed them to work out the optimal electrical power conversion designs for offshore wind turbines up to 15 MW. The research, taking into account the complex set of parameters at play in LCoE, enabled it to develop a Medium Voltage Power Converter reaching up to the 15 MW power range. Ingeteam claims that its new design is the ideal solution for scaling up offshore turbine platforms and will present its converter and the associated research at the Global Wind Summit in Hamburg next month.
