What does the National Grid’s BSUoS cost increase mean for you?


What does the National Grid’s BSUoS cost increase mean for you?

June 17, 2020

Covid-19 and lockdown has seen demand for electricity fall in Great Britain by up to 20%. National Grid, the electricity network operator who manages the electricity system, forecast that the low demand will cost them an additional £500 million in balancing the electricity transmission system.

The additional costs will be recovered through a charge known as Balancing Services Use of System charges (BSUoS) – which generators and end-users are liable for – set to be applied between June and August and an increase of around 90% on average.

BSUoS costs are charged on a half-hourly basis and can range from £0-£20 an hour in a single day, dramatically changing the dispatch patterns of all generation and supply. Furthermore, the charges are only accurately reported around one month after delivery, making it even harder to forecast the real BSUoS cost of supplying as a generator or importing as an end-user.

What do additional BSUoS costs mean for electricity generators and consumers?

If you generate a large amount of electricity (typically 50MW and upwards) and connect to the national transmission system, you will be charged these increased costs per hour of generation. Therefore, your marginal costs will rise by an unknown amount and you will need to charge more for generation. This, in turn, will directly impact the wholesale price of power.

Generators that are connected to the distribution network lower down the system, rather than to the high voltage National Grid (also known as ‘embedded generators’), will be paid these BSUoS rates. Thus, the cost of generation will decrease.

For end-users, the cost of electricity will increase at an uncertain half-hourly cost. Depending on who supplies your electricity, some of this risk may sit with your supplier; especially if you have a fixed fee contract with them that includes assumed BSUoS costs vs higher BSUoS costs.

This is why some larger suppliers are attempting to defer the impact of BSUoS. They want to spread the cost of additional balancing during COVID-19 equally across all the settlement periods during 2021/22 to ease the pain the unprecedented charges could have on them.

In addition, OFGEM is currently consulting on whether BSUoS should be recovered on demand-only (and not with generators) so that we better align with Europe. This would see an increase in BSUoS costs for end-users but would be offset by an equivalent reduction in wholesale market prices. This in turn will impact the power that is flowing to and from Europe to the UK.

The benefit of being a Hartree client in light of BSUoS and Covid-19

For most businesses, there’s a divide between their energy supplier and their asset optimisation partner. Ultimately, this means that they do not benefit directly from the optimisation of assets, instead, the benefits flow to their current supplier.

Here at Hartree Solutions, we become your energy supplier and your optimisation partner so that you are the one who benefits. We pass additional revenues (like those highlighted in the chart below) to you directly or we guarantee you a long-term fixed power price discount. This gives your business savings and certainty that’s not offered elsewhere.

AMPYR Solar Europe Signs Deal with Edinburgh Airport to Develop Renewable Infrastructure

AMPYR Solar Europe (ASE), a pan-European solar developer, and Edinburgh Airport Limited today announce the…

AMPYR Solar Europe (ASE), a pan-European solar developer, and Edinburgh Airport Limited today announce the signing of a deal to develop a new solar farm linked with battery technology and electric vehicle charging infrastructure at Scotland’s busiest airport.

Under the agreement, ASE along with its local construction partner, Absolute Solar & Wind will build approximately 9MW of solar PV, 1.5MW of battery storage and 40 EV charging points. The large ground-mounted solar PV system and battery will be situated next to the runway on a 16-acre plot of land, connected to the airport via a high voltage private wire network.

The development will be a cornerstone of Edinburgh Airport’s goal to achieve Net-Zero by 2040 by generating clean, renewable energy that will cover about 30% of the airport’s total consumption.

“Our commitment to a net zero future is underpinned by the various strands of work we have going on across the airport as part of our Greater Good sustainability strategy and one of the most visible projects will be this solar farm,” said Gordon Dewar, Edinburgh Airport’s Chief Executive. “We are happy to confirm our partners in this exciting step and our collaboration will enable us to implement this technology and allow us and Scotland to benefit from it as soon as possible.”

The project is in the late stage of design, with construction planned to start this summer and be fully operational by the start of next year.

“We are really pleased to be partnering with Edinburgh Airport on this important step towards a net-zero future and in support of its impressive “Greater Good” sustainability strategy,” said Andrew Gould, Executive Chairman of ASE. “Edinburgh Airport’s leadership shows a way forward to zero carbon for the airport sector. This is the first of ASE’s five renewable energy projects in Scotland to reach the delivery stage: the commitment and support of the Scottish Government and its strong policy position on climate change is clearly attractive to international investment.”

Edinburgh Airport will purchase the power produced by the solar farm through a long-term Power Purchase Agreement with ASE. This PPA will generate long-term energy and carbon savings for the airport.

“We are delighted to support Edinburgh Airport with its ongoing drive to reduce its carbon impact,” said Matthew van Staden, Senior PPA Originator at Hartree Partners. “Through our expertise within Hartree and AMPYR Solar Europe, we can drive and deliver innovative energy solutions for companies within energy-intensive sectors. Our understanding of sustainable generation and commercially viable strategies in this space helped bring this project to life for Edinburgh Airport.”

The construction is further supported by the Scottish Government’s Low Carbon Infrastructure Transition Programme, which have provided a grant for a portion of the capital expenditure.

“We are proud to be delivering this pioneering project and helping to decarbonise Edinburgh Airport alongside our funding partners ASE and the Edinburgh Airport project team,” said Tom Newall,  Managing Director at Absolute Solar & Wind. “The co-location of utility scale battery storage and solar PV has enabled us to maximise the green energy generation on site whilst working with the grid connection constraints. We look forward to entering the construction phase before progressing to carry out the operation, maintenance and optimisation of the system, as it generates clean power for years to come, providing energy security for a major, Scottish transport hub.”
