Solar faces up to a self-consumption downer

The week in clean energy saw Germany add momentum to the global trend of self-consumption levies for renewable power use, while wind players enjoyed new-found confidence.


New commercial and industrial renewable power generators will have to pay a charge on the electricity they consume, according to a plan backed by the German Cabinet on January 29. Part of the reform of the Renewable Energy Sources Act, the proposal would mean that from August such ‘self-consumers’ would have to pay 70 per cent of the charge used to pay for renewable subsidies (the Energy Sources Act surcharge), which currently amounts to €0.0624/kWh.

Under the proposal, the first 10MWh would be exempt for owners of solar photovoltaic projects under 10kW. However, the new self-consumption charge would make the economics of installing a larger PV system significantly less attractive.

Some 83 per cent of solar self-consumers would be subject to the new charge, according to the German Solar Energy Industry Association. Many of the details have yet to be finalised but the Cabinet is expected to sign the draft into law in April. It will then go to the parliament for a vote in June.

As part of Germany’s reform of its renewables support mechanism, the government is also considering a reduction in the feed-in tariff from the current average of €0.17/kWh, to €0.12/kWh. The reform aims to lower the cost of the country’s transition towards renewable energy – a transition which has contributed to an increase in residential electricity tariffs to the point that they are now the second-highest in the EU-28.

While the move to decrease support for solar PV may have a long-term impact on installation levels, Germany will still retain the top spot for solar PV capacity. The country’s installed solar power will climb 8 per cent to 38GW in 2014, according to Bloomberg New Energy Finance forecasts. How long it will keep first place is not certain, as it was only a distant fourth for new capacity additions in 2013, after China, Japan and the US.

In any case, Germany is not alone in seeking to reduce the cost burden of supporting renewables by implementing what might be deemed a ‘renewables disincentive’: in December, the Spanish government passed a regulation to implement a new ‘back-up fee’ for existing and new self-consumption systems up to 100kW.

The levy will be in the range of €0.07-0.09/kWh for systems under 10kW. The draft law targets self-consumers in part because they are connected to the grid and require its services. Solar PV self-consumers, in particular, can make significant demands of grid services: during the day they may need to export large amounts of excess power, while at night they still depend on external supply. Net metering could mean these self-consumers do not pay as much as their use of the grid’s economic services might warrant.

In addition to the self-consumption charge, Spain plans to cap the return earned by renewable energy at 7.4 per cent, according to draft rules seen by Bloomberg News on February 3. The rate on investment was based on the average yield on a 10-year sovereign bond plus three percentage points. The 1000-plus pages of regulations, which still need government approval, would implement hundreds of parameters for calculating cost bases, including technology type and connection to the transmission network. Like Germany, the Spanish government’s aim is to curb renewables subsidies. These amounted to €50 billion ($US68 billion) over the last decade. 

The state of Arizona was the first jurisdiction to implement a self-consumption charge, implementing a fixed monthly charge of some $US0.70/kW of installed system capacity for rooftop solar systems, in order to compensate for their use of the grid infrastructure for net metering. As many as a dozen US states are considering whether to follow suit. For example, utilities in California are demanding fees to connect solar panels to the grid. These charges would add some $US120 a year to rooftop users’ bills. These moves are the first response to rising unease about self-consumers, but are likely to gain currency in other countries with high levels of small-scale solar PV.

Despite these potential renewables disincentives, this week has seen some good news for wind power: Germany’s Nordex expects installations in its home market to climb as much as 30 per cent in 2014, even as the government takes steps to cut industry support. The company, which almost tripled wind installations in Germany last year, is seeing an increase in orders by customers seeking to lock in current aid levels before the cuts take hold.

European wind-turbine makers including Siemens and Vestas are working to boost sales and reduce production costs after companies worldwide cut prices to compete for orders with Asian players while governments are streamlining subsidies. Nonetheless Nordex, is “very confident” it can achieve its targets of a 5 per cent margin at the earnings before interest and tax level, €1.5 billion ($US2 billion) in sales and a 15 per cent reduction in production costs on 2012 levels in 2015. Denmark’s Vestas also had good news on February 3 when it reported its first quarterly profit since 2011: net income in Q4 2013 amounted to €218 million ($US295 million), beating analysts’ and its own expectations.

These European wind companies are now seeing their margins improve – not because of an ability to increase prices but because of cost cuts. Vestas and Nordex have both reduced manufacturing capacity and trimmed staff in recent years to prepare for less demand. But after a two-year turnaround plan, the Danish company is now seeking to raise capital this month by selling 20.4 million new shares through a private placement at the market price.

EU carbon

European carbon advanced last week after the European Parliament’s environment committee agreed to accelerate the adoption of a rescue plan for the bloc’s emissions market. European Union allowances for December 2014 finished the week up 4.7 per cent.

EUAs for delivery in December ended last Friday’s session at €5.59/t on ICE Futures Europe exchange in London, compared with €5.34/t at the close of the previous week. EUAs for December 2014 were trading as high as €5.82/t on Thursday after the panel voted 43 to 13 to shorten the measure’s usual three-month scrutiny period in the European Parliament. The recommendation now needs approval from all heads of the assembly’s other committees before it goes to a plenary, which can end the obligatory evaluation before an April deadline.

Prices fell back on Friday to a low of €5.55/t after a member of the EU’s conservatives said his group raised an objection in the European Parliament’s industry committee to fast-tracking the carbon-market fix. UN Certified Emission Reduction credits for December 2014 gained €0.05/t last week to finish at €0.43/t.
