VDE Study Recommends Limited Dynamic Support of New Power Plants Connected to Low Voltage Level in Case of Voltage Drop

A study commissioned by the Association for Electrical, Electronic and Information Technologies (VDE) recommends that new power plants connected to the low voltage level shall be able to provide limited dynamic support for the grids, remaining connected in case of short voltage drops (typically with a duration of approximately 100 milliseconds) to stabilise the grids.

Advisory Committee to BMWi Recommends Electricity Grid Charges Reflecting Grid Utilisation

The Scientific Advisory Committee to the Federal Ministry for Economic Affairs and Energy (BMWi) has published an expert opinion on “Congestion-related Payments by Users and Infrastructure Investments in Grids”, covering the transport, electricity and telecommunication sectors. For the electricity market the report recommends grid charges that reflect grid utilisation.

Agora Energiewende: Energy Transition May Proceed without Electricity Storage for 2O Years – Transport, Heat and Chemicals Markets Will Drive Growth

Up to a share of 60% of renewable energy sources in the energy mix, i.e. for the next 15 to 20 years, the German energy transformation can do without new electricity storage facilities, as there are cheaper options to provide the flexible electricity input needed in view of the intermittent nature of renewables. However, new storage technologies like batteries, power-to-heat or power-to-gas will presumably grow dynamically nonetheless, due to rising demand from the transport, heat and chemicals, a new study presented by the energy think tank, Agora Energiewende, says.

BMWI Study: Expansion of Distribution Grids May Cost EUR 23 to 49 Billion

In view of the German Energiewende that aims to increase the share of renewables of 23.4% in 2013 to 80% in 2050, the Federal Ministry for Economic Affairs and Energy (BMWi) has presented a study on the need for expansion and retrofitting of the distribution grids to which 90% of all renewable power plants are connected. The study quantifies the need for expansion using three potential scenarios and points out and assesses ways to save money by using smart grid technologies and innovative planning and operating strategies.

BNetzA Publishes Study on Capacity Products in the Gas Market

The Federal Network Agency (BNetzA) has published the results of a study it had commissioned on “Capacity Products in the German Natural Gas Market” which was meant to take stock, evaluate and make proposals for a possible standardisation.

Fraunhofer ISI: PV Installations Generate Almost Three Times Higher Profits Than Onshore Wind Despite Lower Yields

In view of the substantial increase of costs for electricity consumers for financial support paid under the Renewable Energy Sources Act (EEG), Fraunhofer Institute for Systems and Innovation Research (Fraunhofer ISI) examined “Distributional effects of the promotion of photovoltaic expansion and wind onshore“. The study shows great differences between the two renewable sources. Photovoltaic installations generate significantly higher profits than onshore installations, even though they produce less electricity overall, Fraunhofer ISI says. The study also points out striking differences between individual federal states.

Study: Municipal Utilities Prepare for Change in View of Energy Transition – Readiness to Cooperate Increases

Municipal utilities prepare for major changes of their business within the next four years. At the same time the readiness to cooperate has increased significantly. These are the main findings of a study on municipal utilities carried out by Ernst & Young (EY) in cooperation with the Federal Association of the Energy and Water Industry (BDEW). The study polled CEOs and managing directors of municipal utilities of different size and and set-up.

Fraunhofer ISE: Strong Increase in Renewable Input in Q1, Particularly from Solar Power Plants

New information by Fraunhofer Institute for Solar Energy Systems ISE show that renewable power input accounted for 28% of the German electricity mix in the first quarter of 2014. Q1 was charaterized by mild temperatures and a high solar and wind power production.

Eastern Germany More Affected by Rising Electricity Costs – Household Electricity Prices Rising to 40 ct/kWh by 2020?

Due its higher than average electricity production from renewable energy sources, Eastern Germany benefits in the area of employment, but its citizens have to bear higher than average grid costs. Having a generally lower income than their peers in former West Germany, the citizens of the five German states that formerly constituted East Germany are also harder hit by the rapidly rising electricity costs in the wake of Germany’s energy transition (Energiewende). These are the mains conclusions of a study on the effects of the Energiewende on the five Eastern German states, presented by the federal government’s Commissioner for Eastern German Affairs, parliamentary state secretary Dr. Christoph Bergner. Electricity prices for private households in all of Germany will rise from currently below 29 ct/kWh to almost 40 ct/kWh by 2020, the study also predicts.
