POWER PLANTS

What we design, develop and install:

Standard finished systems, until 200'000 kWh/a

Custom designed systems, until 2'000'000 kWh/a

The smallest powerplant can be loaded into a minibus, while the large ones are made of concrete, steel and stainless steel.

The drawing below shows the scheme of a K1 system with a car as a size comparison:

The power plants have various sizes:

KX - Kompakt WASSERKRAFTWERK

Drop height: 0.58 m, annual production of about 2'600 kWh / year.

K0 - Kompakt WASSERKRAFTWERK

Drop height: 0.66 m, annual production of about 4'000 kWh / year.

K1 - Kompakt WASSERKRAFTWERK

Drop height: 0.93 m, annual production of about 14'000 kWh / year.

K2 - Kompakt WASSERKRAFTWERK

Drop height: 1.4 m, annual output of about 60'000 kWh / year.

K3 - Kompakt WASSERKRAFTWERK

Drop height: 1.9 m, annual output of about 160'000 kWh / year.

K4 - Kompakt WASSERKRAFTWERK

Drop height: 2.3 m, annual production of about 370'000 kWh / year.

K5 - Kompakt WASSERKRAFTWERK

Drop height: 2.8 m, annual production of about 700'000 kWh / year.

K6 - Kompakt WASSERKRAFTWERK

Drop height: 3.3 m, annual production of about 1'200'000 kWh / year.

K7 - Kompakt WASSERKRAFTWERK

Drop height: 3.7 m, annual production of about 2'000'000 kWh / year.

When we indicate the annual production, we take into account an average value between Amin–Amax, related to actual operation, respectively between 5,000 – 8,760 h/a.

Even more plants, larger than the K7 are possible.

With bigger plant sizes, the performance develops more than the increase in volume of the water. Thus larger the power plants are, the more economic potential they have.

For whom

Energy production companies that have their own power plant fleet and also own hydroelectric plants.

The K4 to K7 and even bigger ones of Kompakt WASSERKRAFTWERKE.

Private persons, families, communities and companies who want to generate their own electricity

Private buildings, farms and small settlements

Construction companies and the military for genius work

Often, even very often, construction companies or the military need electricity precisely where there is none, e.g. in bridge building, road construction or engineering work

ROI - Return of Investment

We have here a very good paid back rate.

The diagram below from the Paul Scherrer Institute shows the ROI for various generation methods. Our Kompakt WASSERKRAFTWERKE are in the range of conventional run-of-river power plants. Larger plants from K5 upwards are even better than run-of-river power plants.

Comparison Voltaic-Wind-Hydro

The installed power is given in kW

The installed power is often spoken of. But this size says not so more. In order to make comparisons between different generation methods, annual electricity production is more meaningful and can be calculated in monetary terms.

Some energy production methods only work for some hours or at partial load at times, especially photovoltaics and wind. So, in order to calculate the energy generated, the average duty cycle over a longer period of time, usually a year, must also be known.

Annual utilization factor or capacity factor - Shows the full load hours per generation method:
Voltaic systems             around 10%, wich is 876 hours off full charge per year
Wind turbines               around 20%, wich is 1753 hours off full charge per year
Hydro system KW²       around 75%, wich is 6570 hours off full charge per year

Voltaics and wind are volatile generation methods and are not base load capable. In opposition, hydro is base load capable.

Voltaic systems provide electricity just when the sun is shining, very little in rainy weather and no electricity at night.

Wind turbines supply electricity just depending on the wind strength, not electricity when there is calm.

Hydro systems supply electricity depending on the amount of water, but continuously.

Comparison example of installed power

Voltaic system              1000 kW
Wind turbine                   500 kW
Hydro system KW²    133 kW (one of our systems between K5 -100 kW and K6 - 173 kW). This corresponds to an annual production of 876,000 kWh/a for all 3 types of generation. It can be seen that the installed performance varies greatly.

Energy production is given in kWh and kWh/a
This production can be calculated in money and so you can calculate the income, yield, return of investment etc. The installed power cannot serve this purpose. This only shows the maximum performance of the system, depending on the annual utilization level.

In addition and in general, there are external costs:

If voltaics or wind turbines feed full power into the grid, there are significant external costs because they produce volatile electricity that is unusable. Since production must always adapt to current demand, laws require energy suppliers to purchase this electricity. This means that additional base-load power plants must be available, which greatly increases the overall production costs. They have to go further.

Networks are being expanded, which also increases costs. Countries with a high proportion of voltaic and wind power therefore also have high electricity prices that consumers have to pay (cogeneration tax – which can be found in every electricity bill).

As soon as these compulsory laws are abolished, a voltaic or wind system will no longer be able to feed into the grid in economical and attractive terms.
