| Case study | Mazovia |
| Description | Mazovia Region – Mszczonów Municipality (Central Poland – Polish Lowland) |
| Region>City>location | Stakeholders of Geotermia Mazowiecka SA (total 52 shareholders: 33 individual and 19 legal entities (incl.: 4 municipalities, 2 regional funds for environmental protection & water management, several local ESCOs, municipal services companies, housing cooperatives). Local authorities: 71% shares, regional funds: 27%, other: 2% |
| Owner | Geotermia Mazowiecka SA |
| Operator | Total 8.3 MWth, incl.: 2.7MWth absorption heat pump (AHP) driven by gas-oil boiler, 1 MWth compressor heat pump (CHP), peak gas-fuel oil boilers 2×2.3 MWth. Average heat production 50 TJ/y incl. ca. 35% geothermal |
| Installed capacity ( MWth) |
4156 m (incl. ~ 250 m separate part supplied by compressor heat pump, CHP) |
| Installed geothermal capacity | 67 geoDH receivers (in 44 buildings), ~31% of flats, 3030 inhabitants (ca. 50% of Mszczonów city population) |
| DH length (m) |
Preinsulated pipes |
| Inhabitants connected | Separate files |
| subsurface and surface technical schemes |
90/70°C and 70/50°C for geoDH cooperating with compressor heat pump, CHP (since 2012) |
| significant pictures if any | 41 – 41 max. discharged water temperature (60 m3/h), no injection (wide range of heat extraction, down to ca. 10 deg. C) |
| Operating Temperature of the DH | 60 |
| Temperature of the geothermal ressource (production – injection) |
6.4 MWth = 6400 kWth |
| Geothermal flow rate |
Absorption heat pump, AHP 2.7 MWth (COP ~1,5) + 1 MWth compressor heat pump, CHP since 2012 |
| Heat Pump if any (power in Mwe and COP) |
11.8 5 TJ/2012 (ca. 40% of heat produced by geoDH in Mszczonów), no cooling |
| Production of heating and/or cooling | part of geothermal water stream produced by Mszczonów IG-1 well supplies the pools in recreation centre (“Termy Mszczonów”) since 2008; part of cooled geothermal water after passing CHP (ca. 10 deg C, TDS ~ 0.5 g/dm3) is supplied as drinking one by local waterworks |
| Others uses (drinking water, cascade uses…) |
2000, under constant modenisation and optimisation (eg. 1 MWt compressor heat pump added in 2011 to extract more heat from geothermal water and to extend the geoDH) |
| Dates of begining and end of construction | early 1990s – 2000, including: early 1990s – first concepts and pre-studies (based on information on geothermal water inflow during drilling deep (4119 m) oil-gas exploration well Mszczonów IG-1, 1996 – launch of the investment project “Construction of geothermal plant in Mszczonów” – that stage included, among others, in 1996-1999 reconstruction of deep oil-gas exploration well Mszczonów IG-1 and its adaptation for geothermal water production (from the aquifer at depths 1602-1714 m), 2000 – completion of geoDH plant in Mszczonów |
| Administration scheme | single well system (production well only) – oil- gas exploration well drilled in 1976-77 was reconstructed and adapted for geothermal water production in 1996-1999. Costs of reconstruction and adoption for geothermal production: ~1.3 mio PLN /330k eur) |
| Investement for geothermal well |
by 2000: ~9.7 mio PLN /~2.6 mio eur/: DH plant, basic installations (AHP, gas boilers, etc.), geothermal water pipeline (production well – heating plant); 2011-2012 (compressor heat pump + acc. Infrastructure): 2.9 mio PLN /~ 700 k Eur) |
| Investement for geothermal heating station |
by 2000:~2.5 mio PLN /~620k Eur/ |
| Investement for DH network and substation |
For total investments in 1996 – 2000 – own sources of Geotermia Mazowiecka SA, regional funds for environmental protection and water management, banks (total 10.6 mio PLN /~2.5 mio Eur/: Own sources (52%), subsidies (32%), commercial credit (12%), preferential loan (4%); Total investments in 2011-2012 (installing of 1 MWth compressor heat pump, CHP and auxilliary infrastructure): 2.9 mio eur /~770k eur): 42% own sources, 58% preferential loan |
| Financing (banks, funds, PPP…) |
1996 – 2000; 32%, 2011 – 2012: no subsidy |
| Amount of Subsidies if any |
No substantial difficulties |
| Difficulties faced | similar as above |
| Administrative permits | according to Polish Energy Law cost of energy production is similar to the price of energy sales (incl. all costs of energy source and district heating, for heating sources >5MWth) |
| Cost of the produced MWh | 64 Euro/MWh (net, including distribution costs) |
| Cost of the MWh sold | 37-101 Euro / MWh (net value, including distribution) |
| Final energy cost structure | VAT 23% for heat price (all sources – fossil, RES) |
| Taxes | 14 years |
