ENERGY PARK MORGENTAL

In Morgental sewage gas is produced together with other renewable energies. © Mensi / pixelio.de

From energy user to producer of green power and heating. The sewage of eight municipalities in the Arbon region is treated at the common sewage treatment plant Morgental. The sewage association Morgental has decided to develop a comprehensive energy park. The focus will not only be on energy efficiency and the use of the generated sewage gas but also on the use of other renewable energy sources such as wood, the sun and biomass for power and heating.

I Description of the measure

Title in original language: Energiepark Morgental

Location of CNA: Switzerland

Municipality / regional entity: Steinach

Category of the experience: Measure
Type(s) of CNA:

Principal nomination: Technological

Thematic field(s):

Principal field: Energy 
Secondary field(s): Energy, Industry & services

Spatial scale: Regional (small scale)
Time & duration:

Start date: 2011
Duration: 2011-2015

Key word(s): energy autarchy, Energy park, renewable energies

Objectives:

Transform the existing sewage treatment plant (ARA) into a comprehensive energy park. Energy autarchy of ARA to the extent possible. Familiarizing the public with a wide variety of methods for generating renewable energy. Contribution to Switzerland's energy and CO2 policy.

Activities:

Six energy projects (as of February 2012) 1) Power plant (2011/2012) (under construction) 2) Local heating network (2011/2012) (under construction) 3) Sewage plant power plant (2012/2013) (funding secured) 4) Wood-based power plant (2012/2013) (funding secured) 5) Solar Field One (photovoltaic plant (2014/2015) (under planning) 6) Biogas plant (2014/2015) (under planning)

Results:

Power: At present, the sewage plant uses 1,4 GWh/year, of which 0,7 GWh/year is produced with the existing gas turbines. The realization of the energy projects will allow an increase of power production to 9-13 GWh/year. Heat: The sewage plant now uses 1,6 GWh/year. The renewable energy of the sewage plant can cover 110% of this heating requirement. With the realization of all energy projects renewable heat production can be boosted to 12-22 GWh/year. CO2 reduction: up to 15,500 tonnes/year (long-term objective). The SF 60 million energy park will eventually be able to provide power and heating for 3,500 households, which corresponds to a municipality with 15,000 inhabitants.

II Assessment criteria

Mitigation effects: Very high

see 13 Results

Impacts on adaptation: Very positive

-

Impacts on environment:


- Landscape: Positive
- Alpine ecosystems / biodiversity: Positive
- Water / soil / air: Positive
- "Other": None

The site of the energy park will also be upgraded ecologically: stream restoration, areas for pioneer plants, wetlands and drylands, afforestation. Appreciable reduction of CO2 emissions, positive effects on air quality.

Impacts on society:


- Social justice: Neutral
- Regional / cultural identity: Neutral
- "Other": None

Impacts on economy:


- Employment / job creation: Positive
- Added value / income: Positive
- Know how / competitiveness: Positive
- "Other": None

Orders for project design and construction. Increased know-how for clients and contractors.

Public relations impact and awareness-raising: High

Predominantly positive response from the population. Strong media response in the region, to an extent the project also has a national and international impact.

Transferability: Very high

Sewage plants can in principle be optimized for the production of renewable energy. To establish an energy park like Morgental, however, requires availability of corresponding land surfaces.

Cross sectoral and integrative approach: Very high

Establishment of a comprehensive energy park (for various renewable types of energy) is inherently a multisectoral and integrative task.

Good governance: Very high

Cooperation between the sewage treatment association, local government, research institutions and private enterprise. Individual projects were/must "have the blessing" of the population (referendum)

III Executive body and contact information

Executive body: Administration

Sewage treatment association Morgental in cooperation with the municipalities, the cantons Thurgau and St. Gallen, the federal government and private enterprise.
