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).

Growth Of Renewables In Peru As Enel Opens Largest Wind Farm In Country

Enel is now Peru’s leading renewable energy generator with around 1.1 GW of installed capacity following the commissioning of Wayra I which, with more than 132 MW, is now Peru’s largest wind farm. Built in approximately a year and comprising 42 wind turbines of 3 MW over each, it’s expected to produce 600 GWh per year; enough to avoid the annual emission of over 285,000 tonnes of CO2 into the atmosphere. The energy generated by the wind farm is being delivered to the Peruvian transmission grid (SEIN) through the Poroma substation. The project is supported by a 20-year energy supply contract with Peru’s Ministry of Energy and Mines.

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%.

Major Wins For Solar As EU Increases Renewable Energy Target

The European Parliament, European Council and European Commission have agreed to a binding 32% EU renewable energy target for 2030, up from the original proposal of 27%. James Watson, CEO SolarPower Europe commented ‘The deal is a good one for solar. We see a much more ambitious target than was expected just a few months ago and importantly we have a strong framework for self-consumption and prosumers. Households wake up this morning with the knowledge that they will have a new right – the right to self-generate, consume and store the energy they produce. This is a major achievement.

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.

Vestas Sets 10.6 GW Record In 2017 After Year-End Surge; Ups Cashflow Guidance

Vestas has received a firm and unconditional order for 190 MW of 4 MW platform turbines in the U.S. taking the global order intake for the company in 2017 to 10.6 GW, surpassing 2016’s record order intake of 10.5 GW. The surge of orders at the end of the year has resulted in the company revising its guidance for free cashflow upwards. It now expects the free cashflow for 2017 to be €1.15bn-€1.25bn, as compared with the previous guidance of €450m-€900m. Markets have reacted favourably with the company share price experiencing an increase of 5%.
