Distribution Future Energy Scenarios (DFES)

Distribution Future Energy Scenarios (DFES)

Distribution Future Energy Scenarios (DFES) is an annual report that forecasts the energy pathways to 2050.

This annual report creates a picture of how the energy system might look by 2050. The analysis models different ‘drivers’ of change; like the uptake of electric cars, low carbon heating, renewable energy or changing consumer behaviours and how they are spread across our licence areas.

The result is four ‘scenario worlds’, each offering a different picture of the future. We publish this as an interactive summary, a technical report, and as interactive maps. We also publish the raw data so users can create their own analysis.

The DFES each December feeds into our strategic forecasting system so it influences our forecasts of demand and generation on every substation for the following year. However, the research isn’t just for our drive to lowering emissions. We want to share insights with local councils, regional planning authorities, businesses, or charities to help them create their own climate action plans.

Benefits

Having excellent data forecasting is a vital tool for us to be able to plan investment in our network, support customers, and deliver insights for stakeholders to enable more electric vehicles, renewable energy, low carbon heating and smart technology.

With a clearer picture of the future, we can make sure we’re doing everything possible to reach Net Zero emissions and help our stakeholders do the same. After our round of engagement last year, we found 90% of local authorities who responded to our survey said they plan to use DFES data to inform their climate action plans.

Flexibility Tender Data

This dataset provides data on eligible postcodes, expected utilisation rates and guide prices, to support Flex Providers in evaluating participation in a flex tender.

Flexibility Tender Data

This dataset provides data on eligible postcodes, expected utilisation rates and guide prices, to support Flex Providers in evaluating participation in a flex tender.

We have consolidated data on each flexibility competition, previously in two places into one. This dataset has two key machine-readable tabs – providing eligibility by postcode and guidance on expected revenue. This makes it easier for Flex Providers with large numbers of assets to automatically evaluate their participation, without manual data-reformatting and matching.

To support all our flex providers, we have also retained the tabs which present the information in a more human-readable way. All our flexibility tender data can be found in the Flexibility Tender Library.

Benefits

Simplifies how Flex Providers can decide whether to participate and how to bid for Flex tenders. It reduces the amount of matching / cross-checking that Flex Providers need to do between multiple datasets.

Distribution Network Options Assessment (DNOA)

This suite of documents outlines UK Power Networks’ approach to flexibility and reinforcement for the future of our electricity network.

Distribution Network Options Assessment (DNOA)

This suite of documents outlines UK Power Networks’ approach to flexibility and reinforcement for the future of our electricity network.

UK Power Networks uses forecasting such as our Distribution Future Energy Scenarios (DFES) to identify our future system needs and network capacity over the next five years. We then source all possible options to meet these needs, compare them and make a recommendation for the optimal solution, presented in the DNOA.

As part of the annual DNOA process, we publish two types of data – the methodology, which explains the process, followed by three documents containing the results for each license area.

This transparent framework helps UK Power Networks prioritise flexibility and reduce related expenditure by £410m by 2028, while meeting the future capacity needs across our network.

Benefits

The DNOA is designed to help customers plan their investment in flexibility, opening up new markets and facilitating lower-cost capacity.

Curtailment Events

Daily generation curtailment data showing reduced network access for our flexibly connected renewable generation customers.

Curtailment Events

Daily generation curtailment data showing reduced network access for our flexibly connected renewable generation customers.

Curtailment is where a generator is required to reduce its export capacity so that the network can continue to operate safely, reliably and securely. For example, if the reverse power flow across a transformer is above its allowed rating, we must secure the network by reducing it through curtailment.
This dataset is updated daily and shows all instances where flexible-connection customers have been curtailed by our DERMS system aggregated to the constraint.
Due to commercial sensitivities we do not share individual customer information, however, customers will have access to their own site-specific curtailment soon.

Benefits

  • Help to inform any future developments that you may have.
  • Help you see the nature of that quoted constraint, which adds greater transparency and critical investment information to your business case.

132 kV Historic Power Flow Data

Historical half hourly power flow data (active power and current) across 132kV circuits within UK Power Networks licence areas aligned to our long term development statements.

The cables and overhead lines that travel between our grid supply points and our grid substations are known as 132kV circuits. The DSO will release the historic power flow data for all monitored 132kV circuits within our licence areas. This includes the release of historical half hourly active power (MW) and current (Amps) flows across all 132kV circuits (where possible) from 2021 to last month.

To make the data more accessible and interoperable, the cables can be linked with the equivalent naming in the Long-Term Development Statement Publication (LTDS).

 

 

Benefits

Customers applying for non-firm access arrangements have been requesting historic power flow data to facilitate their own curtailment studies to gain deeper insight on the level of curtailment the site could operationally be subject to and to inform the viability of the investment.
