The prosumers have the future

11 April 2017: The joint use of renewable energy should become the main pillar of a future energy system. The prerequisite for a boom in so-called "prosuming", however, is that citizens' energy actors consistently develop their strengths and that politicians continue reducing regulatory barriers. These are the two most important findings from today's report "Citizen's Energy – Today and Tomorrow", presented by the Alliance for Citizen's Energy and Büro F in Berlin.

New business models for municipal utilities in Germany

15 July 2016: Through the combination of photovoltaics with battery systems, the direct local supply is becoming more and more attractive. Energy utilities now have the opportunity to activate prosumers as long-time customers. This can be achieved through the sale of hardware such as battery home storage kits in combination with the smart integration of the prosumers into the electricity markets (e.g. marketing of pooled storage capacity).

What happens if the market for home storage units grows like the market for private PV units
did between 2004-2011?

19 May 2016: Photovoltaic was once underestimated and laughed at - nowadays you see offers for solar demonstratively placed on the homepages of E.On, RWE, EWE & Co. What happened? There's one thing that renewables have that conventional energy sources don't: they emotionalize. The power of this "story" is now visible in the sales figures for home units.  Although most unit owners would be better off with a PV unit optimized for their own needs, around 50% of the newly installed units are mounted on private rooftops together with home storage units. Are we on the verge of a storage unit boom?


Energy transition solved: Storage unit and digitalization show the way to the future of energy economy

7 April 2016: The digital integration of battery storage units into the energy system is the next big step in the energy transition, according to current studies by the Berlin-based consulting firm Büro F and enviacon international. The market research results are discussed and further developed with market leaders and scientists at the conference “Energy Storage Lab” on April 19, 2016 in Berlin.


What does "digitalization in the energy sector" really mean?

6 April 2016 - "Digitalization in the energy economy" is discussed often these days. But what does it really mean? We understand it as the IT-based communication link between various components geared toward the control and aggregation of production, creation of networks, storage and consumption. The potential and also risks of an increasingly digital linkage, especially for the integration of battery storage units, are discussed on April 19, 2016 at the conference "Energy Storage Lab" in Berlin: www.energystoragelab.de


Large-scale battery storage on the rise

20 January 2016 - According to the technical university RWTH Aachen, 20,000 home storage systems were installed last year. We are even seeing heightened market activity in the area of battery mass storage. After the installation of the first ten pilot plants in the megawatt area, at least nine more large-scale storage systems have been announced for the year 2016. On top of that, numerous projects are being developed, surfaces for transformer stations are being secured and feasibility studies are being carried out. Here is an outline map of large-scale storage in Germany:


Business models for operating large-scale storage systems:

Marketing of capacity on balancing markets

Currently, the most frequent business model for operators of large-scale storage systems is the participation in tenders for frequency control. According to data from Younicos/WEMAG, in the first operating year 2014/2015 the 5 MW large-scale storage system in Schwerin achieved revenues at an average of 3,810 euros per MW of primary operating reserve capacity provided weekly. The prequalification for battery storage systems in order to be able to participate in the control energy market is, however, described as very difficult. For example, the requirements for the large-scale storage system in Feldheim even changed during construction, according to information from informed sources.

Neighborhood storage systems

The energy provider MVV has developed a concept with „Strombank“ with which operators of PV and CHP plants jointly use a neighborhood storage system and take electricity as required. The investment costs are lower than for the installation of small home storage systems; yet, business models for the realization of neighborhood storage systems are still in the test phase.

Intake of electricity surpluses from PV and wind power plants

Operators of large PV and wind parks can integrate an electricity storage system to optimize their electricity marketing. For example, the 1.3 MW-large-scale storage system in Alt-Daber is fed by a 68 MWp solar park from Belectric. Next to the direct marketing of electricity according to the German renewable energy promotion scheme EEG, an additional source of income becomes viable via participation in the balancing markets.


New markets for electricity from renewable energy sources

14 December 2015 - Ideas for the direct and regional marketing of ecofriendly electricity are currently experiencing strong momentum. According to a survey carried out by Büro F among 42 energy market experts, “marketing of renewable energies” is the most frequently cited “interesting new business model”. The issue of regional direct marketing of renewable energies will in all likelihood even play an important role in the EEG 2016. Here is a systematic presentation of the current offers and market actors:

The overview makes clear that new sales channels are arising for RES electricity by means of direct sale and the optimization of private consumption. Next to the sale of “green electricity” from feed-in tariff plants, these also include regional electricity and peer-to-peer models, for example from unsubsidized plants. In the end, the pooling of prosumers and the current boom in tenant electricity are also relevant for sales channels for RES electricity. Technical solutions, business models and the demand for direct electricity products are thus arising. The potential here is analyzed in a current study by Büro F: “Energy Business Lab – New Business models in distributed and digitized electricity markets."


New study on successful models for energy companies

11 November 2015 - The market research firm “Büro F –New Energy Markets” is releasing a new study on actual success models for energy companies. The primary finding: successful energy suppliers will be, in the future, bringing together different roles under one roof and will evolve to become Pool Managers. They will produce their energy in a decentralized manner, will market renewable energy, finance new energy plants and steer flexible energy consumption. On one hand, these business models are tied to the usual tasks of the energy companies. On the other hand, companies can, via digital solutions and storage technologies, open up new business areas for themselves and combine the existent in a new way.

The Federal Ministry for Economic Affairs and Energy’s white paper hardly brings impulses for the decentralization of energy provision

06 July 2015 - Federal Ministry for Economic Affairs and Energy (BMWi) has presented a white paper with 20 concrete measures for further developing the power market. It quickly becomes clear: The white paper aims to flexibilize the existing system, and not to decentralize energy provision. In a short analysis, Büro F has compared statements from an expert survey on the most urgent adjustments to the regulatory framework with concrete measures in the BMWi’s white page. The conclusion:

  • With the white paper, measures to flexibilize energy systems are initiated, yet the focus lies on the integration of fluctuating renewable energies into the existing system;
  • The paradigm shift toward decentralized energy provision with high actor diversity is clearly thwarted (for example, there are no measures for: regionalizing wholesale trade, strengthening private consumption, integration of storage units);
  • Impulses for new business models are created with the opening of markets for control energy, measures for load management and the subsidization of CHP plants;
  • Numerous new business models for battery storage devises and private consumption will however not have attractive regulative framework conditions even after the implementation of the measures laid out in the white paper.


Trade fair report Intersolar Europe 2015: the product “electricity” in focus

15 June 2015 - Electricity generation by photovoltaics has become a given. Now the focus is becoming more and more the use and marketing of inexpensive solar energy. Correspondingly, a heavy rush dominated at the leading trade fair Intersolar Europe among the providers of storage solutions and integrated energy systems. Although the products and services presented hardly pay off yet: This is where the next push toward distributing the power supply is to be expected. Classic solar companies, on the contrary, presented above all gradual improvements in the cell and module technologies to increase performance class.
