Economic reasons for the operation of a wood-CHP 
2.1 Which form of energy is the best?
 

Energy is the source of energy in various forms. Gas is collected in square meters and kWh, liquid gas in liters and also oils in liters. 
If you want to compare energy prices, must bring the energy to a common denominator. 

 

For considerations for CHP operation, it makes sense with price / kWh to be expected. 

 

These energy carriers on a unit must be converted. 

1 square meter natural gas corresponds to approximately 10.05 kWh (Factor see gas billing) corresponds to 1 liter of fuel oil approximately 10.00 kWh 

 

1 liter of LPG equivalent to about 6.70 kWh (at 18 ° C) 

1 liter of rapeseed oil equivalent to about 7.00 kWh 

1 kg of wood pellets corresponds to 5 kWh electricity can be counted directly into kWh.

 

 Energy is a commodity and is buying into the various sources of energy or to reflect in the most refined form, as electric power.

2.2 CHP: energy prices compared 

 

When electric power is to be produced from organic waste and wood, then you have created an advantage over the reference to the market electrical price. 

After consolidation of the electricity market, ie from the 2000's the difference between the kWh price of gas, oil and electric grown so large that the "refinement" of wood gas has become useful to electrical energy. 

 

For the assessment of whether a CHP is economically, electricity costs are to provide the supply of electricity compared to. In the overview, the difference between the prices can be clearly seen . 

 

The average price (gross price determined from prospective inquiries) were in 2014: ·

 

Natural gas about 5.5 cents / kWh 

Heating oil about 5.5 cents / kWh ·

LPG about 6.5 cents / kWh ·

rapeseed oil ca. 7.5 cents / kWh ·

Electric energy about 28.0 cents / kWh (Work Retail Price) 

Commercial customers have to keep in power references to current to reflect low. 

 

Here, the kWh price is often very opaque about 17-24 cents / kWh are common. 

 

In order to determine its average kWh price is the surest way, the total cost with respect to calculate electrical counter charges by consumption in kWh.

 

This all serves as power prices, energy tax, CHP surcharges and current control are taken into account. 

 

2.3 Wood gasification CHP:

 

From the most inexpensive form of energy for the highest quality power electric energy is the most widely used energy. 

 

Extensive power grids allow the consumption of electric energy almost at each location. 

 

If you want a pro rata basis to create your own energy from wood, needed an inexpensive energy source. 

 

The example is intended to show what costs in the generation of electric energy. 

 

For example, fuel wood chips as residual material in carpentry or landscaping [insert calculation example] 

 

2.4 wood gasification cogeneration

 

Heat is not a waste product in the production of electric power generates heat. 

 

Prorated depending on the drive of the CHP. As an example, a CHP with an electrical capacity of 15kW and a gas 4Y engine is assumed (power to heat ratio 0.33). 

 

Also, the heat generation must be taken into account. 

 

The heat makes the most of the production of the CHP out. 

 

Only when the heat is needed, the electric energy can be produced economically. 

 

For this reason, calls for the legislature that the wood CHP as opposed to large-scale power plant "heat run" have to work. 

 

If the fuel is purchased too expensive, the overall balance is too high heat generation costs negatively. 

 

This point must be borne in mind especially with expensive wood chips or pellets, which are requested erstärkt due to the increased demand. 

 

Here is often looked at the feed-in tariffs, without considering the heat generation costs. 

 

Take finally the opportunity to claim to seek to create a factual and not based on commission feasability study by professional wood gasification energy consultant!

 

In the heat generation costs are in addition to share maintenance and capital costs also saved energy tax refunds considered. This however applies only to oil and gas CHP.
