The way we use electricity is changing. With the rise of renewable energy sources, electric vehicles and local generation, the energy landscape is evolving. But new solutions bring new challenges. We are investing in technology to transform this critical infrastructure to accelerate grid modernization, with energy storage as a buffer for tomorrow’s power grids. With the introduction of energy storage, we now have the technical capabilities to create resilient grids that work effectively with renewables, microgrids and local generation and can limit investments in larger grid capacity.
Unlock the full potential of renewable energies. By combining renewable energy sources with storage, the peaks of solar and wind energy can be captured and offered to the market when it is most interesting. Renewable energy projects with energy storage will offer added value in the coming years compared to projects that are only renewable. At the moment we are working with multiple owners of solar and wind farms to integrate the business case for solar farm and energy storage, the bottleneck of transport costs is an important challenge.
By linking your solar roof to storage, you can use as much solar energy as possible yourself. GIGA Storage is working with developers of solar roofs on the business case for installing energy storage on their solar roofs, so that as much green energy as possible can be used even when the sun is not shining. Energy storage can also be used to reduce peak consumption, which can result in significant savings on transport costs for larger consumers. In addition, there are increasing restrictions on having grid connections adjusted. There are both supply restrictions and redelivery restrictions, depending on the region. GIGA Storage is working with a developer of solar roofs to calculate the business cases to realize self-sufficient new-build energy. The aim is that the user of the building no longer obtains energy from the grid, but uses the generated energy on his own roof. This goes a step further than energy neutral on an annual basis and results in enormous CO2 savings.
Reliability of the distribution system
Increase the system operational efficiency and improve the stability during failures. The distribution network is increasingly burdened by new tax sources, such as electric vehicles, and local generation. Battery storage can accommodate intermittent local generation and isolate the grid from sudden spikes in local load, and so unloading the distribution infrastructure. Energy storage can manage the output of reactive power, usually simultaneously and independently of the real power. Such reactive power can be used to provide services that maintain the mains voltage. This is a vital local service that protects equipment, maintains power quality and reduces transmission losses. GIGA Storage will soon start a study with a DSO to further develop the use of energy storage in its network, more information will follow.
Energy storage is the most responsive and flexible asset available and can neutralize the volatility caused by, for example, renewable energy sources in the grid. Energy storage has no minimum set point and is bi-directional – it can supply power from the network, absorb it and act as a buffer.
Transmission and distribution
Increase the existing transport capacity without immediately building new lines. Traditional grid capacity expansion projects are large capital investments and have a long lead time. The strong growth of renewable energy sources cannot be solved by expanding grid capacity alone. In addition, the grid was built to be able to transport the top 10% of peak demand, which usually occurs in less than 1% of the year. With the energy storage systems of GIGA Storage, these peaks can be absorbed, which means that investments in the network can be partly reduced. By including energy storage in strategic locations in the distribution network, congestion is avoided and the disconnection of renewable energy sources is avoided.
