Advantages of our services

high share of renewables

With our analysis, we aim for the highest possible share of renewables given your case-specific boundary conditions. This will help you to meet your climate goals and surpass the political targets and make it easier to be eligible for public funding. Further, renewables can make your energy system more resilient since you are independent from fuel price shocks or fluctuations.

cost-efficiency

Traditional analysis uses rough estimates for renewable energy sources and the corresponding infrastructure and thus overestimates the size of inverters as well as batteries. However, these components significantly contribute to the overall cost and an overestimation here leads to either a low percentage of renewable energies or a higher cost for electricity distribution. Our analysis works with more accurate models saving cost.

reliability of the grid

A low power quality leads to lasting damages and a shortened lifetime of grid infrastructure as well as your customers’ industrial and household appliances. With our analysis, you can check on the influence of connecting renewable power plants or electric vehicles and whether your grid remains in an operation with high stability and power quality. For different weather and load scenarios we  help you to collect the necessary data for better understanding your power system. Further, we can advise you on how to best build grid stabilizing infrastructure. This way, grid operation is made easy and a high power quality is ensured for your customers.

basis of decision-making

In the decision-making process, many stakeholders are involved with their own needs and goals. We can show different pathways to a higher share of renewables or different future scenarios and analyse the technical and economical implications. Our reports and analysis results deliver a thorough foundation for our customers critical business decisions.

streamlined processes

With our experience in project management and by structuring our processes for data acquisition, modeling and communication of results, we offer streamlined processes around our analysis. By taking into account all the details from the very beginning, we help you to stay in the scheduled time frame.

 

Our Services

Grid Optimisation Report

for an optimal grid

With our tools for asset management with optimal power flow solvers we minimize investment and maintenance cost and show you how to build your grid in an optimal way. Here, we point out how much capacity of which energy carrier makes the most sense for your project and on its impacts on cost and the energy mix. By also taking the grid into account, we can deliver deeper insights into the technical feasibility and static stability. This helps you to plan your resources efficiently and save cost.

Dynamic Analysis

for a stable grid

With our novel methods for dynamic or transient stability analysis, we are closer to reality than other analysis tools or consultancies. We can do estimates on the possible amount of renewable energies in the grid and give realistic recommendations on where additional infrastructure needs to be built if the share of renewables is increased. These analyses give you the assurance that there will be no problems in operation and that a high power quality can be guaranteed to your customers.

Scenario Analysis

for transparent decision making

No matter how good our engineers are: Nobody knows the future. What will be political guidelines for renewable energy in the next 10 years? How many electric vehicles will connect to the grid within 5 years? In order to be prepared for changes the future might bring, we offer to develop realistic scenarios and perform grid optimisation and dynamic analysis for each scenario. This way, you are well prepared for events that are likely to happen.

Data generation and validation

to master big data

In order to perform analysis, a lot of data is needed. How to generate load profiles for households, renewables or electric mobility? How to aggregate the data needed from different systems and databases? We offer solutions for these challenges helping you to deal with your data efficiently and deliver good estimates when there is no data available. We also offer the possibility to extract data from commercial software like Neplan, Homer, PSSE or PowerFactory for our analysis. Like this, we are helping you to make the most out of your data.

Individual Analysis and Services
