Use cases & success stories

Learn from our use cases

• Battery

  The battery plays an important role as a storage buffer in local electricity management, both for self-generation, optimal use of price volatility, and for the security of electricity supply. How the battery is used, however, is crucial for its quality and lifespan.

  
  The Embion EMS provides functionality that allows the user to efficiently manage electricity, achieve good returns, and respect the battery's lifespan.

• Curtailment

  Curtailment literally means limitation or shutdown and is an EMS function used when generating local electricity from renewable sources such as wind or solar energy.

  On a sunny day, solar panels can generate so much electricity that it cannot be stored locally because all buffers, such as batteries or boilers, are already fully utilized. If the electricity price on the market at that moment is also negative, it is more cost-effective to temporarily limit or shut down the solar panels.
  Curtailment is also applied when the feed-in of locally generated electricity exceeds the maximum contracted feed-in capacity. Without limitation, this could lead to penalties for the end user.

   

• Energy hub

  An energy hub, or e-hub, is created when multiple companies connected to the same electricity loop of the grid operator share and manage electricity from generation, storage, and consumption.

  The e-hub provides participating companies with greater collectively contracted import and export capacity and more control capacity. This results in more available electricity at lower costs and with lower CO₂ emissions.
  Setting up an e-hub has advantages but requires good organization and clear contractual agreements between participants and with the grid operator. Our recommendation is to first map out your own electricity management in a structured way using the Embion EMS, and then explore and implement the collective benefits of an e-hub together with neighboring companies if it is meaningful.
  The strength of the Embion EMS is that each company with the same Embion Controller can use both individual and collective EMS functions at the moment it suits them.

• Electricity savings

  By implementing an EMS, a user can save an average of twenty to thirty percent on annual electricity costs. The exact savings depend on factors such as the available controllable capacity, the grid management contract, the weather, and electricity price volatility.
  The user’s objectives also play a role. For example, one can prioritize maximum use of green electricity over minimal electricity costs. The Embion EMS ensures that these goals are met daily, something that is impossible to do manually, thereby maximizing results.

• Energy monitoring

  Insight into electricity consumption, generation, and storage is important for awareness and for monitoring the performance of the entire installation.
  Additionally, governments are introducing more regulations that companies must comply with and report on. The Embion EMS provides multiple dashboards that give all the necessary insights.

• Energy storage in water

  Electricity can be stored in two ways: in a battery or in water.
  Electric boilers are a good alternative to battery storage. Excess electricity can be used to heat water in the boiler. Since the boilers are well insulated, the water remains hot for a long time and can be used during the day for heating, cleaning, or showering.

  The Embion EMS ensures that buffer capacity, whether battery or boiler, is effectively utilized both when electricity is abundant and when prices are low or even negative.

• Managing import and export limits

  Every company with an electricity connection has a contract with the grid operator that specifies maximum import and export capacity. This is important during grid congestion; exceeding these limits results in a warning, then a penalty, and repeated breaches may lead to temporary disconnection from the grid.
  The Embion EMS prevents exceedance by starting, stopping, or dimming connected devices at the right moment within the user-defined goals and control limits.

• Controlling charging stations

  The transition to electric mobility is mandated by the EU. It is important that charging of electric trucks, vans, and cars can take place quickly and safely throughout the country. This leads to charging stations and plazas equipped with solar panels and batteries.
  Vehicle charging is influenced by many variables that are not always predictable. An EMS is essential to ensure optimal charging, both in terms of user experience, efficiency, and operational reliability.

• Load shifting

  Load shifting involves moving energy consumption from peak hours to times with lower energy rates or when more renewable energy is available.
  During peak hours, electricity is often more expensive and the network is heavily loaded. The Embion EMS uses load shifting to move energy consumption to cheaper or greener periods. This reduces peak loads, optimizes energy use, and contributes to more sustainable and cost-conscious energy management.
  Load shifting plans consumption smartly throughout the day to minimize costs and impact on the grid.

• Avoiding grid congestion

  Generated energy is used or stored immediately, preventing feed-in to the electricity grid. This results in more efficient use of renewable energy sources, lower energy costs, and contributes to a sustainable energy supply. By coordinating energy consumption and storage with production, waste is avoided and the energy transition is supported.

• Peak shaving

  Peak shaving prevents high spikes in energy consumption. By managing grid load within controllable limits, peak shaving ensures the electricity network is not overloaded.
  The Embion EMS uses smart inverter control to automatically limit power when load is high. This prevents unexpected costs, distributes energy efficiently and sustainably, and contributes to a more stable electricity grid.

• Control according to energy prices

  Electricity prices are set on external markets and depend on factors such as supply and demand, fossil fuel prices, and CO₂ pricing. There are multiple markets, such as day-ahead, intraday, imbalance, and futures markets, where electricity is traded and prices are determined.
  If the end user wishes, the Embion EMS can respond directly or indirectly to price fluctuations in these markets to purchase electricity more cheaply or sell self-generated or stored electricity at a higher price.
