Energy tender and energy optimization

Based on your consumption profile we evaluate the potential for savings regarding your power and gas supply contracts. We handle the tendering for your consumption point in compliance with public procurement directives. Moreover, we also implement energy optimisation measures. These could for example consist in the construction of a solar power system or the installation of hydraulic power recovery turbines to generate energy.

Analysis and tendering of your energy supply contracts

As an engineering office, we have worked with municipalities and water boards in the areas of water supply, drainage, sewer systems and wastewater treatment for many years now. In the course of our daily work we often notice that clients tender their electricity and gas supply contracts only sporadically or not at all.

We therefore support municipalities and water boards, regularly and legally compliant with energy tendering / energy optimization by conducting tenders for electricity and gas supplies. We are often able – through advice and assistance – to reduce our clients’ expenses dramatically.

How do we do that?

With our“OPT-Energie” product, we help you to achieve optimum conditions when awarding supply contracts for electricity and gas.

What are the concrete steps we take?

Free of cost and without obligation, we analyse your consumption profile and point out saving potentials. When conducting tenders according to the regulations, we can rely on years of experience and our extensive knowledge of the electricity and gas markets.

How do you benefit?

You will not have to monitor contract deadlines anymore, and neither do you need to keep track of electricity and gas prices or deal with the tender procedure, because we will do all of these tasks for you.

The special feature:

We will not bill you for our service. Instead, if you successfully save costs, we will receive a certain amount of the annual savings for two years.

Case studies

Municipality in Hesse

A municipality of about 7,900 inhabitants in Hesse has annual energy needs of approx. 860,000 kWh of electricity and 1,300,000 kWh of gas for its real estate, street lighting and metered delivery points. Based on our analysis of the relevant data, we were able to show the municipality great potential for savings. Through orderly tendering with separate lots for electricity and gas supply, the energy costs will be reduced by about €59,000 per year.
