James Watt on the subject of contracting.

“We will let you have a steam engine at no charge.

[…] We guarantee you that the coal for the machine will cost less than you must currently spend on fodder for the horses.

[…] And all we ask of you is that you give us one third of the money you are saving.“

James Watt (1736 – 1819)

Energy contracting in the technical perspective

Delivered energies and media

Contractor Useful energies and media e.g.

Electricity

Fuels(natural gas, oil)

Water (drinking water)

Hot water

Compressed air

Steam

Cold water

sewage refuse

Improvement of energy efficiency

in all steps or parts of theprocess

starting from production / conversion into

useful energies and theirdistribution to the

customer

Partial renewal of electrical systems

Compressed air:

Partial renewal of entire compressed air and feed air systems at the factory

HOCHTIEF Energy ManagementTechnical concept

Organisational measures

Transition from customer staff in accordance with BGB §613a (German Civil Code)

Changed the technical department from “cost center” to a “profit center”

Additional internal benefits (pensions, wages etc.)

More responsibility and shorter decision routes

Highly trained stuff through continued education

Motivated stuff “Energy service is our core business”

Contracting also means:A fair distribution of risks!

Risks born by the contractor HTEM:• Efficiency risk (realization of guaranteed savings)• Availability risk (liability and insurance)• Risk of a prime contractor (investment)• Risk of legally compliant operations

Risks born by the customer:• General price development (end consumer energy, specific working costs etc.)• Location risk

- Financing (based on customers creditworthiness) - Collateralization
