State of Lower Saxony launches funding programme for battery storage systems
Published
The state of Lower Saxony has launched a new funding program for battery storage. The funding guidelines were published in the Lower Saxony Ministerial Gazette on 21 October. Applications can be submitted to the NBank with immediate effect.
The grant funding of up to 40 percent of the net investment costs of a battery storage system applies in connection with the new construction or expansion of PV systems (at least 4 kWp). In addition to natural persons, grant recipients can also be companies, legal entities, municipalities and many others.
In addition to the subsidy, bonuses can be granted for e-charging points, PV systems over 10 kWp and the roofing of parking areas or other structural facilities with elevated PV systems.
The funding programme is carried out as a support programme for the economy in the context of the Covid19 pandemic. The grantees are to make investments and thus contribute to the promotion of the economy. The programme is therefore limited in time, Applications can be submitted until 30.9.2022.
It is estimated that the care and integration of refugees will cost 20 billion euros in 2016. In the programme Frontal21 from 24.5.2016 (from (minute 25 to 33) figures are given on how some providers of refugee accommodation charge horrendous prices. According to their research, the costs of accommodation per refugee range from 87 to 1,100 euros per month, in the extreme case of Velbert (near Wuppertal) even 1,500 euros per refugee per month.
In the contribution of the Time from 23.05.2016 costs for refugee accommodation are mentioned for various locations in Hamburg. These range from 10 to 38 euros per person per day, which corresponds to around 300 to 1,140 euros per person per month. It is interesting to note that small locations are not necessarily more expensive than large ones.
The topic of the construction costs of refugee accommodation is taken up by the German contribution to the 15th International Architecture Biennale 2016, which can be found on the website www.makingheimat.de can be seen. There are 54 different refugee buildings in the database comparing the net costs. The range of net costs is between 1,000 and 2,300 euros per m² GFA (cost group 300 - 400).
According to a recent survey of Germany's 700 largest cities and municipalities, only 6 percent of municipalities feel overwhelmed by the current refugee numbers.
In a recently written short study, scientists from the Department of Energy System Analysis at the Fraunhofer Institute for Solar Energy Systems ISE prepared an evaluation of the Market Master Data Register (MaStR) and the EEG system master data for photovoltaics (PV). Important findings of the analyses were that with 38 percent of the newly installed capacity, the increase in capacity in Germany is increasingly taking place in the segment of rooftop systems larger than 100 kW, 22 percent of the newly built PV systems are erected in a west, east or east-west direction and 19 percent of these systems have tilt angles smaller than 20 degrees.
The Market Master Data Register (MaStR) is the register for the German electricity and gas market. Since January 2021, all electricity generation units connected to the general supply grid must be entered in it. This also applies to the steadily growing number of photovoltaic systems in Germany. In addition to the master data on output and location of a PV system, which has already been recorded in the Renewable Energy Sources Act register (EEG system master data), the market master data register records further information such as orientation, inclination and output limitation.
These parameters have now been analyzed by scientists at Fraunhofer ISE. The evaluation covers the period from 2000 to the present day and shows the development over time in terms of number, power, location by federal state, orientation, inclination and power limitation. Different evaluation criteria were taken into consideration, which allow statements to be made on the following aspects: Plant addition, power addition by plant class, plant addition by federal state, plant orientation and inclination angle.
Fraunhofer ISE evaluates these central parameters at regular intervals and makes the results publicly available. In addition, the Institute offers further evaluations of this database on request.
82 percent of the added systems are smaller than 10 kW
The evaluation of the installation of new systems by system class essentially shows that the <10 kW size range has remained constant since 2014 with an average share of 82 percent. Rooftop systems over 10 and up to 100 kW had a heyday between 2004 and 2011, when their share of new installations - in relation to the number of systems - averaged 43 percent.
Growing part of the added capacity is due to large rooftop systems
When examining the increase in capacity by plant class, it becomes clear that the high share of the <10 kW plant class in terms of the number of plants is only reflected in a high increase in capacity to a limited extent. The share of the plant class has remained fairly constant at an average of 19 percent since 2014. One system segment whose relative share of capacity growth has increased sharply is the system class of rooftop systems from 100 to 750 kW. From 17 percent in 2012, their share has more than doubled to 38 percent in 2019. In contrast, the importance of ground-mounted systems has declined from 45 percent in 2012 to 20 percent in 2019.
More than half of the PV systems will no longer be built in Bavaria and Baden-Württemberg
The two states of Bavaria and Baden-Württemberg accounted for an average of 59.6 percent of new installations in Germany between 2000 and 2009, and this share declined to an average of 44.5 percent between 2010 and 2019. Over the same periods, North Rhine-Westphalia increased its average contribution from 14.1 to 18.3 percent, Lower Saxony's share rose from 6.5 to 9.2 percent, and Brandenburg's share increased from 0.7 to 2.2 percent. All the remaining federal states also recorded increases, albeit to a lesser extent. Despite the decline in their share, Bavaria and Baden-Württemberg remain in first and second place in terms of new installations in 2019, with 24.4 percent and 18.6 percent respectively. This is followed by North Rhine-Westphalia, Lower Saxony and Hesse with 17.9 percent, 9.2 percent and 6.1 percent respectively.
73 percent of newly installed PV systems are limited in their capacity
Only around a quarter of the newly installed plants in 2019 do not have any output limitation. According to the EEG, 66 percent of newly installed plants may only feed a maximum of 70 percent of their output into the grid because they do not have remotely controllable feed-in management. This proportion has grown by an average of 4 percentage points per year since 2014. The remaining output-limited plants have even higher limitations of 60 to 50 percent as a result of the combination with a battery storage system.
Increasing proportion of PV systems facing east and west
While the share of PV systems with southern orientation decreased from 61 percent in 2000 to 42 percent in 2019, the share of systems with eastern and western orientation increased at almost the same rate: east from 1 percent in 2000 to 7 percent in 2019, west from 3 percent in 2000 to 9 percent in 2019, east-west from 1 percent in 2000 to 6 percent in 2019.
Plants are increasingly being built with a lower angle of inclination.
The share of added PV systems (rooftop and ground-mounted) with a tilt angle of less than 20 degrees averaged 10 percent between the years 2000 and 2009. Subsequently, between 2010 and 2019, the share increased to an average of 19 percent. Systems with 20 to 40 degrees of tilt accounted for an average of 63 percent between 2000 and 2009, falling to 54 percent between 2010 and 2019.
On the costs of modernisation measures for tenants
In November 2016, the Working Group on Tenancy Law in the RAV published the brochure "Price Driver Modernization" was published. It describes in detail the problematic effects of modernisation measures on tenants. In addition, the authors criticise the legal situation and call for fundamental new regulations under tenancy law.
