Tieto – decentralising the centralised – why district heating must change electricity history united states


Its monopoly-like market position is slowly receding, and emissions are hard to push down. Deep geothermal heat and small modular nuclear reactors are unlikely to reach commercial status soon enough to offer a silver bullet for climate battle or improve short-term competitiveness of district heating. save electricity images Large-scale excess heat sources are scarce, and biofuels won’t secure sustainable heat production in the long run, either. This means it is time to stop the ongoing adversarial dialogue between camps of district heating and distributed heat production.

District heating has been a great way to warm buildings in densely populated areas in the Nordics. This is because of economies of scale and a highly developed and efficient operating model. That is why district heating demand has grown steadily in the Nordics – with a market share in Finland and Sweden around 50%. During the last ten years, though, the average price of district heating in apartment buildings has gone up roughly 30% in Finland and 20% in Sweden in real terms. mp electricity bill payment online bhopal Fuel costs, emission allowances and other regulatory costs are rising, and without a major decline in district heating companies’ margins, prices will continue to go up and dig into customers’ wallets. gas leak los angeles california Customers will be enticed to seek ways to lower their heating costs.

At the same time, competing technologies, mainly heat pumps, have developed fast. Today, the levelized cost of heat produced with ground source heat pumps and air-to-water heat pumps is of the same magnitude as the district heating tariffs in the large cities of Finland and Sweden. Increasing variable electricity production in the Nordic area further improves the competitiveness of heat pumps by lowering the electricity market price. Why decentralise?

To optimise the whole district heating value chain, companies need to be able to also have access beyond the building’s heat exchanger. District heating companies can and will update their production capacity on the primary side as well, but value-adding services will be introduced on the secondary side, in buildings. gas monkey monster truck hellcat There is lots of recent research on large-scale heat pumps in district heating systems, but from a more systemic perspective of the subject, multiple benefits arising from decentralised model can be identified:

Decentralisation is inevitable. It will happen regardless of the decisions district heating companies make. The only uncertainty is how the decentralised assets are operated in the future. gas under 3 dollars Who is taking the driver’s seat? What role should the district heating company take? How are the costs and benefits divided between stakeholders? These are just a few questions company executives should be asking today. Towards virtual heating plants?

From a district heating company’s point of view, the change could mean decentralisation of assets or decentralisation of both assets and control. Economies of scale could be applied, if decentralised heating assets are controlled in centralised manner. f gas certification logo Together with larger heat production units, these assets form a virtual heating plant, which is the heating sector counterpart to a virtual power plant.

In addition to cutting down emissions and having control of the whole heat value chain from production to consumption, there are also other benefits in a virtual heating plant. Decentralised assets, such as heat pumps, enable district heating companies to participate in various energy marketplaces and offer flexibility to the market, thus improving return on heat pump investment. Also spot market optimisation can be profitable, especially when heat pumps are used against marginal heat production capacity in a district heating system. electricity production We understand the scope of the challenge

Tieto supports district heating companies by providing tools and expertise to manage a decentralised and data-driven future. electricity youtube Yet we understand that as the complexity of the energy system increases, the more partnerships need to be formed, because there is no one solution that alone can change the game. We know this from experience: we are already piloting distributed energy solutions in the electricity sector. Best practices from there can be used in future-proofing the heating sector as well.
