SuedLink project

After NordLink, now is time to see how SuedLink works!
Germany has set itself an ambitious goal to provide at least 80 percent of its electricity generation from renewable energy resources (RES) by 2050. In Germany, electricity generated by RES is mainly locally in the windy north and sunny south of Germany. Thus, the power grids must be adapted for ensuring a stable and secure power supply in the future. Powerful direct current (DC) lines such as SuedLink play a decisive role here. To see how does it work, let's watch this interesting video (turn ON  english (or other preferred) subnoscript).

Netzbooster project
#Germany

The energy transition poses major challenges for the transmission grids. There are already grid bottlenecks in the power grid, for example when more power is generated in wind farms in the north of Germany than the existing lines can absorb. In order to avoid such a bottleneck in the network, power generation in the north is being cut back preventively. At the same time, power plants are being started up in the south in order to avoid regional overloading of the network and the failure of a line and to ensure security of supply. This adaptation of the active power feed-in of power plants by the transmission system operator is called (preventive) redispatch .
Such interventions in the network by the transmission system operator are expensive and uneconomical - and less ecological than if the renewable electricity could actually be consumed. In the course of the expansion of renewable energies, grid bottlenecks must be expected even more frequently in the future. It is therefore important to systematically expand the power grids. This means that more electricity can be transported away and security of supply can be guaranteed even without redispatch.
But before building new power lines, existing power grid must be optimized.
In Netzbooster project, it makes a decisive contribution to increasing the transmission capacity on the existing lines. As a safety buffer, however, the network booster only actively steps in if there is a fault in the transmission network and a bottleneck as a result.
I invite you to watch TransnetBW nice demonstration of Netzbooster concept in the following.

When talking about the energy transition, we often hear about the increasing need for the use of flexibility to be able to efficiently guarantee the security of supply.
But what is the definition of flexibility?

According to the International Energy Agency, the flexibility of a power system refers to "the extent to which a power system can modify electricity production or consumption in response to variability". In other words, flexibility is the modification of generation injection and/or consumption patterns in reaction to an external signal (price signal or activation) in order to provide a service within the energy system.
The parameters used to characterise flexibility include the:
• amount of power modulation,
• duration,
• rate of change,
• response time,
• location

Flexibility Markets

New technologies are changing the way the energy system works. As the energy system relies more and more on renewables, and more and more energy use is electric (for example because of e-mobility and electric heat pumps for heating) the electricity system becomes more decentralised and interactive.
Flexibility markets help energy networks to monitor energy flows and create market signals to motivate changes in energy supply and demand, integrating smart meters, smart appliances, renewable energy resources and energy efficient resources accordingly. With this background, let's watch the following video demonstrating how flexibility markets work which provided by NorFlex project team.

Local Energy Market

A Local Energy Market is the term used to describe initiatives to establish a marketplace to coordinate the generation, supply, storage, transport, and consumption of energy from decentralised energy resources (e.g. renewable energy generators, storage and demand-side response providers) within a confined geographical area [1].

Let's have a look at the following video which provided by Centrica plc describing how Cornwall Local Energy Market works.

Peer-to-peer (P2P) energy trading is the buying and selling of energy between two or more grid-connected parties. Thus, P2P is introduced as one approach for energy sharing in communities and local energy markets. Often in the form of solar energy, any excess energy can be transferred and sold to other users via a secure platform. P2P energy trading allows consumers the choice to decide on whom they purchase electricity from, and who they sell it to.
Currently, excess solar energy is exported back to the grid for a small feed-in tariff rate. However, this method is becoming obsolete as more people are looking for flexibility and control in managing how their resources are distributed.
The trading of energy is done through a secure platform, often using a technology like blockchain. Blockchain is a database technology that processes and stores information, such as transactions of assets. These assets can be in the form of renewable energy credits, which can be traded through the database. P2P energy trading platforms such as blockchain will allow consumers to share their excess energy amongst one another and control how it’s distributed through microgrids. Users who both sell and consume energy are called ‘prosumers’. Let's watch the following animation provided by Localvolts.

The expansion of renewable energy, specially  in distribution networks, is rapidly increasing as part of the energy revolution. The structure of energy supply systems is becoming increasingly decentralized (decentralization). New players, such as prosumers, who generate and consume their own electricity, could establish themselves in the electricity market. On the one hand, due to their low capacity, prosumers are currently unable to participate economically in electricity trading. In this way, we need a new energy trading environment, so-called local energy market, for prosumer. On the other hand, the increasing complexity of control and the load on the network infrastructure as well as the high requirements on data security, which are associated with the exchange of electricity and the associated electricity bills, require digitalization of the energy revolution. Thus, The blockchain technology as a driver of the energy revolution for the development of new digital business models can contribute to the successful transformation of the energy system. Blockchain technology promises economic value through its strengths such as disintermediation, security, transparency and automation. However, in addition to technical challenges such as the upcoming smart meter rollout, the smart meter gateway required for communication, and the compatibility between the smart metering systems and the blockchain, there are also legal and regulatory hurdles which make the use of the blockchain difficult in the short-term. By far the most widely discussed usage of blockchain in the energy sector is the peer-to-peer trading of decentralized electricity from renewable energies.
Let's watch the following video prepared by Bosch India which presents how blockchain technology can help us to realize P2P trading in energy communities.

OPT1MIN: Unraveling Renewable Energy Certificate (REC) in 1 min

A Renewable Energy Certificate (REC) is a tradable commodity that represents the environmental attributes associated with one megawatt-hour (MWh) of electricity generated from a renewable energy source, such as wind, solar, or hydro power. RECs are used to track and incentivize the production and consumption of renewable energy, allowing electricity consumers to support renewable energy generation even if they do not have direct access to it. When renewable energy is generated, the associated RECs can be sold separately from the physical electricity, providing revenue to renewable energy producers and enabling consumers to claim they are using renewable energy even if they are connected to the conventional grid. This mechanism helps stimulate investment in renewable energy projects and promotes the transition to a more sustainable energy system.

Are Renewables really Green? Is the aim Green resources or GREENER resources?

🖥[Youtube]

Renewable energies are often labeled as "green" due to their lower operational emissions compared to fossil fuels, but their environmental impact extends beyond just emissions. While they emit fewer greenhouse gases during operation, the production and deployment of renewable infrastructure can involve environmental costs such as raw material extraction, habitat disruption, and land use changes. Despite these impacts, renewables generally offer a more sustainable alternative to fossil fuels when managed responsibly throughout their lifecycle, emphasizing factors like resource efficiency, responsible sourcing, and minimizing ecosystem disruption during installation and operation.

How Dynamic Electricity Tariff can facilitate Local Flexibility Markets?

📺 [Youtube]

Dynamic electricity tariffs can play a pivotal role in facilitating local flexibility markets by incentivizing consumers to adjust their electricity consumption patterns based on real-time price signals. By offering variable rates that reflect supply and demand fluctuations, consumers are encouraged to shift their usage to periods of lower demand or higher renewable energy generation, thus reducing strain on the grid during peak times and maximizing utilization of renewable resources. This creates opportunities for local flexibility markets where consumers can participate by offering demand response services, such as load shifting or curtailing, in exchange for financial rewards or incentives. Additionally, dynamic tariffs promote the adoption of smart technologies and energy storage solutions, enabling better integration of renewable energy sources and enhancing overall grid resilience and efficiency.
