More and more wind and solar farms are on the way. This growth in sustainable energy is taking the electricity grid to full capacity, with the result that sustainable energy is sometimes being curtailed out of necessity. That’s a lost opportunity, since what we actually want is to accelerate the energy transition. SemperPower has the solution: energy storage systems. Safe and reliable.
Our electricity grid can no longer rely on gas and coal plants
The Netherlands is in the middle of transitioning to a one hundred percent sustainable energy system. Fossil fuel power stations must be closed down more quickly due to the large quantities of CO2 they emit. Challenges such as balancing supply and demand, and handling peaks in generation and consumption, have until now been managed by these gas and coal power stations. But now we have to wean ourselves off these fossil fuel power stations, we face a new challenge.
These are the four greatest challenges in the Dutch energy transition
- A new energy mix results in a discrepancy between supply and demand.
- Grid imbalances produce large swings in electricity prices.
- Sustainable energy is wasted because of lack of grid capacity.
- Long lead times for new business electricity connections.
Challenge 1: Discrepancy between supply and demand due to new energy mix
We’re making good progress; the energy mix is changing. There are ever more electric vehicles, wind and solar farms are popping up everywhere, roofs are full of solar panels and households increasingly are turning away from gas. Unfortunately, generation from wind and solar power isn’t easy to predict. Peaks in production and consumption, and discrepancy between supply and demand, are set to increase even more in future.
Challenge 2: Grid imbalances produce large swings in electricity prices
The discrepancy between supply and demand makes the grid more difficult to balance, and the supply of electricity more uncertain. This creates sharp fluctuations in electricity prices, adversely impacting the whole population and bringing all of the attendant economic consequences.
Challenge 3: Sustainable energy is wasted because of lack of grid capacity
Ever more wind and solar energy is being generated. But this rise in simultaneous generation of green power results in sharp spikes in production. The result? Generated sustainable energy has to be wasted. There is simply no capacity to transmit this over the high-voltage grid. For a successful energy transition, generated sustainable energy needs to be fully and better utilised.
Challenge 4: Long lead times for new electricity connections
The congestion in the Dutch grid means that businesses are unable to obtain new electricity connections. In fact, supply and stability can no longer be guaranteed by the grid operators. This means long lead times! The Dutch economy is growing but long lead times for a connection mean that not every business can share in this growth. One temporary solution for the planned grid expansion is the construction of an energy storage system.
Large-scale energy storage is the future
Flexible energy storage is needed by wind and solar farm developers, grid operators (DSOs and TSOs) and industrial consumers. SemperPower has the solution, by deploying ‘large batteries’ - also known as battery energy storage systems (BESS) - with which we can store sustainable energy during times of oversupply, releasing it again when demanded by the market.
Only by working together can we can accelerate the energy transition
Large-scale energy storage is needed now. So that we can fully utilise sustainable energy. So that together, we can contribute to the Sustainable Development Goals (SDGs). So that SemperPower, together with the grid operators, authorities, landowners, wind and solar farms and industrial consumers, can get on with accelerating the energy transition in the Netherlands. We all have to work together on the road to a fully-sustainable energy system.
All about SemperPower energy storage systems
1. What is an ESS or BESS?
2. What type of battery is being utilised?
We currently employ high-grade lithium-ion (Li-ion) batteries for our energy storage systems. They’re the safest option, and are highly versatile in technical applicability. We install the energy storage system in a modular configuration, in which the various elements can be in any desired configuration.
3. What about fire safety?
The modular units in our battery energy storage systems are very safe. That’s because unlike Li-ion batteries for electric bicycles and vehicles, they are not in direct contact with the weather. In addition, our batteries comply with the most stringent fire-safety standards. Their static configuration means any fire cannot spread to a neighbouring element, and no question of explosion hazard arises.
4. How is the quality and service life of these batteries?
5. How can the battery be controlled?
SemperPower has developed its own management software (trading and asset management IT systems). A BESS is a complicated system that is complex to manage. We have translated this into our software and as part of that developed a client portal. This allows consumers to easily communicate with the systems through the API.
Our software makes controlling the system easy.
6. Where will a BESS be located?
7. What about the permitting of a BESS?
The spatial impact of a battery energy storage system is small. It isn’t a fire risk, emits little noise and there’s almost no visual impact. A BESS is also a temporary, no-regrets measure. Unfortunately, little has so far been set out in current legislation and regulations. That’s why we’re happy to help authorities with the challenging task of fitting-in energy storage.
