    Considerations for forecasting non-commodity costs for large users

    Electricity non-commodity costs, also known as Third Party Charges (or TPCs), are faced by the vast majority of end consumers that use electricity. They represent a significant proportion of the energy bill for domestic, SME and large industrial user types; however, their applicability and scale can vary depending on the...

    Network charging – what’s been going on and why should I care?

    Across Great Britain there are ~810,000km of wires and underground cables that make up our electricity network. Split between the higher voltage, transmission system and the lower voltage distribution system, these lines and cables are responsible for transporting electrons up and down the country to provide consumers with the necessary...

    What to look out for in Third Party Charges in 2022-23

    In recent months, the GB energy market has been exposed to extreme volatility as wholesale prices have grown rapidly, leading to a significant number of supplier exits and questions over consumer affordability of energy bills. This has resulted in notable movement across a number of non-commodity costs (also known as...

    Location, location: The increasing complexity of embedded benefits

    There is growing recognition of the need to reform our current network arrangements to support a more dynamic and flexible electricity system as we undergo the transition to net zero. Among the network elements currently going through a period of review are Distribution Use of System (DUoS) charges, which recover...

    Electricity transmission charging reform – overtaken by changing priorities?

    Charging for the transmission network is never out of the development process for long. From major reviews, such as that initiated under Project Transmit in 2010, to significant reforms such as removing the triad benefit from distributed generation in 2018, and a host of smaller developments, change seems the only...

    Up north and down south – trends for generator TNUoS charging

    The topic of generator Transmission Network Use of System (TNUoS) is becoming a subject of increasing interest for stakeholders as regulation, policy, and the generation mix create potential volatility for future charging trends. The significant costs posed through TNUoS are an important consideration for generators, with high variability between regions...

    New transmission charge forecast will help generators managing cost uncertainty and volatility

    Transmission network use of system (TNUoS) charges represent a significant proportion of operating costs for many renewables generators, often exceeding 50% of annual running costs. For some, as recently highlighted by SSE in a recent report and to Members of the Scottish Parliament, they could present a barrier to investment in generation...

    Ofgem’s Network Access and Forward Looking Charges review – should I be interested

    Spoiler – if you are a distribution connected generator, yes, In a big way Ofgem is currently progressing one of its biggest overhauls of network charging; with the Targeted Charging Review having only recently concluded that is quite a statement. We have already seen the value to distribution connected generators...

    Editor’s Pick | Ofgem delays Transmission Demand Residual change to 2022

    The regulator has accepted a request by National Grid ESO (NGESO) to replace the current CUSC proposal to implement the Targeted Charging Review (TCR) decision for a fixed residual transmission network use of system (TNUoS). A new implementation date of 1 April 2022 will replace 1 April 2021. NGESO submitted...

    Storage story: a regulatory run-down

    While electricity storage has long been recognised as a crucial solution to mitigating the drawbacks of some types of renewable generation, it has taken some time for the regulatory and charging framework to catch up. It has taken years, but recent progress on the licensing and exemptions from some final...

    Tomorrow evening could see electricity demand peak for this winter

    The latest forecasts from National Grid for electricity demand indicate that tomorrow’s (21st January 2020) evening peak will see the highest half-hour demand so far this winter, with approximately 49GW for the period commencing 17:30. As such, this is therefore likely to be one of the Triad periods used to...
