German energy balancing

By Dave Elliott

Germany is in the lead globally with its ambitious renewable energy programme, already supplying over 32% of its electricity and aiming for 80% by 2050.  At present, Germany’s 1.5 million photovoltaic solar installations have a generation capacity of over 40GW, four times the remaining 10.8 GW base-load nuclear fleet that is being decommissioned in stages between the end of 2017 and 2022. PV can be well matched to day-time peak demand in Germany, which is why it has challenged gas peaking plant in this market.  However, due to its low load factor (10-15%, compared to 70-80% or more for nuclear), solar PV generation only delivers around 940 equivalent full-load hours of electricity per year, so in 2015 its high capacity only met around 7.5% of German electricity demand, compared to 14% for nuclear generation. That’s why some think it is not the best option to expand for the future – it’s expensive for relatively low levels of actual output. (more…)

EU Renewables round up

By Dave Elliott

Renewables are roaring ahead in Europe, with wind at over 140GW and PV surpassing 100GW. There have been some spectacular successes, with renewables briefly supplying 87% of German electricity at one point, and Portugal achieving similarly high contributions-something that’s a regular occurrence in Denmark. But progress may soon be slowed as  economic pressures mount and political reaction sets in with support schemes being withdrawn or constrained. For example, in Germany it’s all change as the government revises the Energiewende energy law with a slow down for wind and solar expansion, via annual capacity caps and reduced support levels. Portugal has also started to phase out its support for renewables, although not quite so aggressively as happened in Spain, or, for that matter, the UK. (more…)

PV solar in Germany: too much of a good thing?

By Dave Elliott

An interesting study from the German Development Institute (DIE) of Germany’s ambitious green energy policy asks whether its support for PV solar, and its subsequent rapid expansion, has been a good idea. PV has expanded to over 38GW to almost match wind, now at 40GW, but it has been a costly exercise, since PV was much more expensive than wind. As a result PV has received the lion’s share of support, up to 3 times more than wind, in part since it expanded under the Feed-in Tariff much faster than expected. And although its costs have dropped dramatically, it is still getting proportionately more of the subsidy. Too much some say.

German energy policy and phasing out coal

By Dave Elliott

The influential German Advisory Council on the Environment (SRU) has mapped out how it sees the future of coal. It notes that the Federal Government Coalition agreement (2013) states that: ‘the conventional power stations (lignite, coal, gas) remain an indispensable part of the national energy mix for the foreseeable future’, but it tries to put more flesh on that vague timescale, so as to better meet and exceed the 80% carbon reduction goals of the existing energy transition plan – it wants that raised to 95%. In particular it says that, with nuclear now being phased out (all of it by 2022), ‘an integrated energy policy should synchronise the phasing out of conventional power generation capacities and the increasing use of renewables’.

Prosumer integration

By Dave Elliott

The German Environment Agency (UBA) has produced a comprehensive review of options for removing almost all (95%) greenhouse gas emission by 2050, based on the existing 80% renewables programme for electricity supply, but also looking at all the other sectors – including heating and transport. As I said in my coverage in an earlier post, that is pretty challenging. But it says it can be done. www.umweltbundesamt.de/publikationen/germany-2050-a-greenhouse-gas-neutral-country

Grid balancing ‘needs extra firm capacity’

By Dave Elliott

Even ‘very significant’ storage, demand-side measures and interconnection would not be sufficient to cope with intermittency in a weather-dependent renewables-based electricity system, according to modeling, up to 2030, by the Energy Research Partnership (ERP). It says there would still be a need to have a significant amount of zero-carbon firm capacity on the system too – for dark, windless periods. It could, for example, be supplied by nuclear, biomass or fossil fuel plants with Carbon Capture and Storage (CCS).

More changes in Germany

By Dave Elliott

Germany  is pushing rapidly ahead with renewables, aiming to get 80% of its electricity from them by 2050.  The nation briefly obtained 78% of its electricity from renewables in the summer. But that was obviously a one-off event. Even so, averaged annually, it’s over 30%: http://energytransition.de/2015/07/renewables-covered-78percent-of-german-electricity/

Germany stays on course

 By Dave Elliott

Germany is sticking to its ambitious plan to get at least 80% of its electricity from renewables by 2050. As part of that, it aims to support the construction and operation of 20 offshore wind farms, 7 GW in all, and that plan recently received a boost, with the European Commission agreeing that it did not conflict with EU state aid rules. The 17 wind farms in the North Sea and three in the Baltic will further EU energy and environmental objectives without unduly distorting competition in the Single Market, the EC said.

Energy storage – new ideas Part 1

By Dave Elliott

Energy storage is usually seen as a very good idea – it would help cope with variable renewables. Indeed some enthusiasts now even say that cheap battery storage will make PV solar so viable at the domestic level we may not need grid power!  Or even grids!  That seems unlikely – they help to balance variable demand  with  supply  from a range of sources near and far. But one thing is clear – energy storage, large and small scale, is becoming a big issue, with many new ideas emerging.    (more…)

PV solar in Germany

By Dave Elliott

PV solar continues its spectacular price reduction and that’s led to large-scale deployment, as in Germany, which now has around 36GW in place, and globally, with around 180 GW. PV was initially expensive, but prices are now much lower, thanks in part to Feed In Tariff systems around the EU, as under the EEG law in Germany, which has helped create a large market. With FiT levels now cut, will it continue to expand?
