KPIs originally described in the Roadmap had to be
reviewed and made more concrete, testable and
quantifiable … assumptions were needed!
It was difficult to trace the link between
objectives/accomplishments in the monitored projects and
the KPIs

KPIs on Shallow geothermal:
Costs reduction
Version 2018 Value of the KPI and general statements
Decrease the energy input for operating the geothermal heat pump system by 10% in 2020 and 25% in 2030
(from 2014 value: 44.6 MWh electric, for a geothermal system capacity of 50 kWth in a new building, supplying heating at T = 35°C during 2200 h per year and cooling at T = 7°C during 1200 h, in western Europe climate conditions, use a SPFheating of 4)
• A lot of expectations from ongoing RD&I
• Decreasing by 5% to 10% in 2018 in mature markets, more in juvenile markets
• Value of 40.1 - 42.4 MWh electric
Reduce costs for operating the geothermal heat pump system, leading up to 20% costs reduction of the O&M in 2020, and 30 % in 2030
(from 2014 value: 9430 € per year, for a geothermal system capacity of 50 kWth in a new building, supplying heating at T = 35°C during 2200 h per year and cooling at T = 7°C during 1200 h, in western Europe climate conditions), assumed with stable energy prices (or statistically levelled).
• Annual maintenance, control costs have decreased
• Performance improved so less electricity input
• Assume a 5% costs reduction of the O&M between
2014 & 2018
• This should lead up to 10% costs reduction of the
O&M in 2020, due to many R&D actions.
• But cost in € is stable as electricity price rose.
KPIs on Shallow geothermal:
Costs reduction
Reduce investment costs for a geothermal heat pump system, leading up to 20% costs reduction in 2020, and 30 % in 2030
(from 2014 value: 68’000 €, i.e. 1360 €/kW, for a geothermal system capacity of 50 kWth in a new building, supplying heating at T = 35°C during 2200 h per year and cooling at T = 7°C during 1200 h, in western Europe climate conditions)
• Assume a 5-10% costs reduction of the
investment costs between 2014 & 2018
• Drilling: reduction esp. in juvenile
markets
• Materials: reduction of 5-10%
• Installation: reduction of ca 10%
• HP: reduction in mature markets
• First assumption of a 10 to 15% costsreduction of the investment between2014 & 2018 for large projects, inparticular in juvenile markets.
Improve efficiency SPFheating
Increase value of Seasonal Performance Factor in the order of 4.5 for 2020 and 5 for 2030
(from 2014 value: SPFheating average of 4, for a geothermal system capacity of up to 50 kWth, supplying heating and DHW at T = 35°C, in western Europe climate conditions)
• Average European SPF is in the range 4 to 4.5 in 2018 for these systems (50 kWth)
• This Performance Indicator has been improved by more than 40% over the last ten years, as shown by field tests and monitoring (cf. SEPEMO, Fraunhofer field study).
Increase value of Seasonal Performance Factor in the order of 5 for 2020 and 5.5 for 2025
(from 2014 value: SPFheating average of 4.5, for a geothermal system capacity of 50-100 kWth, supplying heating at T = 35°C, in western Europe climate conditions)
• Average European SPF is in the range 4.5 to 5 in 2018 for these systems (50-100 kWth)
