Simply put, the storage is a hole in the ground with a liner able to withstand a maximum of 95oC hot water. But the PTES is the first heat storage in Copenhagen, located outside in the distribution network but optimized by the transmission network.
VEKS (municipality owned heat transmission company) and HTF (consumer owned heat distribution company) has implemented a Pit Thermal Energy Storage (PTES) in Høje Taastrup, Denmark to provide flexibility to the

These include solar heating, large-scale heat pumps, biogasification of organic waste, geothermal energy, and surplus heat from industry. Denmark is also heavily invested in wind turbines and thermal storage facilities that give
"Thermal energy storage offers numerous benefits, including improved economic performance and increased flexibility in district heating systems. Decoupling production from consumption enables the integration of more sustainable heat sources."
The plant contributes an annual value of DKK 6-7 million to the district heating network for the entire Copenhagen metropolitan area of Copenhagen and makes a decisive contribution to decarbonization.
These include solar heating, large-scale heat pumps, biogasification of organic waste, geothermal energy, and surplus heat from industry. Denmark is also heavily invested in wind turbines and thermal storage facilities that give consumers access
The projects are operated through a central control system that optimizes storage and power flows helping stabilize and balance the grid. This final stage is where the full value of the project is realised through active management, trading

Since the 80ties large scale thermal storages have been developed and tested in the Danish energy system. From 2011 five full scale pit heat water storages and one pilot borehole storage have been built.
This paper followed the process of realizing a sector-coupling investment in a thermal energy storage in Copenhagen from 2017 to 2020. The analysis shows that while plans may help to define technological qualities and purposes, they do not always convince actors.
The projects are operated through a central control system that optimizes storage and power flows helping stabilize and balance the grid. This final stage is where the full value of the project is realised through active management, trading strategies, and ongoing optimization.

Copenhagen''''s district heating relies largely on biomass and waste incineration power plants, but net-zero carbon targets are now encouraging suppliers to harness energy from renewables and industrial by-products.
VEKS (municipality owned heat transmission company) and HTF (consumer owned heat distribution company) has implemented a Pit Thermal Energy Storage (PTES) in Høje Taastrup, Denmark to provide flexibility to the electricity production system and the heat production system in Greater Copenhagen.
