Good result thanks to positive business development and non-recurring regulatory effects
– This Wednesday, 50Hertz, the transmission system operator responsible for Northern and Eastern Germany, presented its balance sheet for 2012. According to this, revenue rose from 7.004 billion EUR in 2011 to 8.555 billion EUR in 2012 (in accordance with the IFRS). The main driver for this increase was the profit from renewables, despite this being a transit item without effect on net income due to the remuneration and surcharge mechanism of the German Renewable Energy Act (EEG). The actual grid turnover approximated 845 million EUR last year, compared to 759 million EUR in 2011.
In accordance with the IFRS, the results after tax amounted to 111 million EUR (2011: 54 million EUR). In addition to the continued grid expansion, the reduction of negative regulatory factors and the resulting non-recurrent catch-up effects are the main reasons for the positive result. These one-off effects include the faster approval of investment costs and the regulatory progress made in determining capital investment costs. The very high need for financing to ensure liquidity had a strong aggravating effect due to the extremely negative EEG account balance. For 50Hertz alone, the cash outflow on the EEG account amounted to approx. 530 million EUR in 2012. To further ensure 50Hertz's liquidity, 200 million EUR of additional borrowed capital needed to be acquired.
Investments showed a slight increase to 254 million EUR in 2012 (2011: 245 million EUR) and reflect the continued grid expansion to integrate renewable energy sources. 144 million EUR of this amount fell to onshore investments, whereas 110 million EUR fell to offshore investments. In total, the integration of renewables takes up 90 per cent of all investments made by 50Hertz, which was the only German TSO certified in 2012 as fully ownership unbundled by the German Federal Network Agency.
The energy transition is making headway: more renewable energy sources are used to generate power and progress is made in grid expansion and grid conversion
According to 50Hertz CEO Boris Schucht, the high level of investment best proves that in 2012, the implementation of the energy transition made a lot of progress in the 50Hertz grid area. By putting the Northern Line connecting Schwerin and Hamburg into operation, as well as placing innovative new high-temperature conductors on the highly congested line between Remptendorf (Thuringia) and Redwitz (Bavaria) on the South-Thuringian section, two important projects to expand and reinforce the grid were realised. Furthermore, clear progress was made in the approval procedure of several line construction projects, the construction of the second section of the important South-West Interconnector, between Erfurt and Altenfeld, was approved and started, and the connection of the Baltic 2 offshore wind farm to the grid is currently under construction.
Another evident sign of the positive development of the energy transition's implementation is the fact that the share of renewable energy in power consumption increased to 35 per cent (approx. 35 terawatt-hours) in 2012 at a relatively constant power consumption of about 98 terawatt-hours in the 50Hertz control area over the past three years. "This means that Germany's climate policy target to raise the share of renewable energy in the total power consumption to 35 per cent by 2020, has already been reached in 2012 for the new Länder as well as the city-states of Hamburg and Berlin", emphasises Schucht. Schucht also sees the nationwide grid development plan as well as the introduction of further legal measures to ensure system security (through the system stability and disconnection ordinance) and improve the offshore investment framework as progress made in 2012 towards the implementation of the energy transition.
Ambitious investment programme planned
Despite the generally positive development in the integration of renewable energy, the pace of the grid expansion is still inadequate compared to the high expansion rate of renewable energy sources. For reasons of system stability, 50Hertz needed to intervene in the grid and, as a result, in the market on a great many occasions in 2012 as well. On 77 days in total (compared to 45 days in 2011), renewable power station operators needed to be instructed to temporarily lower their production to avoid grid congestion. This solution was always used as a last resort to maintain system stability, after switching interventions had already been carried out and production by conventional power stations had been decreased.
In view of the high grid load and the ever increasing capacity of renewable energy, 50Hertz's grid requires further development. For the next decade, i.e. by 2022, the company plans investments of some four billion EUR, specifically for the continued integration of renewable energy, to reach a high level of security of supply and to develop the unified European electricity market.
Better synchronisation between EEG and infrastructure expansion
This investment in the conversion of the energy supply system requires a political framework to provide planning and investment security. Boris Schucht considers this year's adoption of the Federal Requirement Plan Act an important milestone for the expansion and conversion of the German power grid. At the same time, however, the Renewable Energy Act requires a fundamental amendment to bring it up to speed with current developments in the field of renewable energy. "It goes without saying that we need to keep developing renewable energy as a power source in order to make the energy transition a reality. Nevertheless, this development should be synchronised more closely with the expansion of the required infrastructure. The largest threat to the energy transition is its waning acceptance by the general public. This fundamental acceptance can only be maintained if we can, as before, provide a maximum security of supply at affordable energy prices. This should also be the focus of the future development of the EEG", concludes Boris Schucht.
