What does a DMES earn at your site?

Fourteen questions provide enough information for an initial conversation. They are the same questions our engineers ask before calculating a plant.

It requires about 5 minutes and does not commit you to anything. If you do not know an answer, simply choose “Not known yet”. This will not count against you.

What is this about? Where would the system be located? (postcode and town) Sector What do you have in mind first and foremost?

Not clear yet? Then leave it open, we will work it out together.

Energy basis

This section covers renewable generation, the surplus you can actually use and the energy scale of the project.

Annual electricity consumption

Under 50 MWh/year 50-100 MWh/year 100-200 MWh/year 200-500 MWh/year 500 MWh-1 GWh/year 1-2 GWh/year 2-5 GWh/year Over 5 GWh/year Not known yet

You will find it on your annual statement from your energy supplier. An estimate is sufficient.

Renewable energy

No renewable energy in place or planned Renewable energy is being considered but no specific installation is planned An installation is specifically planned Renewable energy is already in place A large renewable-generation capacity is in place Several renewable sources, or sources secured long-term, are in place

Surplus energy

There is no usable renewable surplus The surplus is small or rarely usable A material surplus occurs occasionally A surplus occurs regularly There are large, frequent or curtailed surpluses Not known yet

Which renewable sources are in place or planned?

Photovoltaics Wind power Hydropower Biomass and biogas Renewable grid electricity or PPA Other

Site and permitting

This section covers the available space, technical siting and the current position on permitting and fire protection.

Space available

There is no suitable space The space available is not known yet Space is tight and conversion work would be required Sufficient space is available in principle Sufficient space and room for expansion are available

Siting

No suitable site is apparent The site still needs to be assessed Siting would only be possible with major adaptations Indoor, outdoor, rooftop or covered siting is possible Several suitable siting options are available

Permitting and fire protection

A permit is unlikely to be possible Permitting and fire protection remain completely open A permit appears possible in principle Authorities or fire-protection have already been involved informally A positive preliminary assessment is already available

Which type of siting would be an option?

Outdoor siting Container siting Plant room Indoor siting Roof Covered siting Still to be determined

Use and economics

This section covers electricity and heat use, the required storage duration, economic benefits and flexibility potential.

Use of the electricity

The electricity generated cannot be put to sensible use Use would only be possible occasionally The electricity can be used regularly The electricity can be used all year round and as required

Use of the heat

The heat produced cannot be used Use of the heat remains unclear The heat can be used occasionally The heat can be used regularly The heat can be used all year round at a suitable temperature level

Storage duration required

Storage is required only for minutes to a few hours Mainly day-to-night shifting is required Storage over several days is required Storage over several weeks is required Seasonal or long-term storage is required The required storage duration required is not yet known

Economic benefit potential

No additional economic benefit is apparent Limited economic benefit is apparent An economic benefit appears possible in principle Relevant energy, grid or operating costs can be reduced Very high economic benefit or flexibility potential The economic potential has not yet been quantified
