General Conference Theme: How UK could have a low-cost, low carbon and reliable renewable energy-based system.
We have selected speakers to give their insights into how a renewable and reliable power supply can be constructed at minimum cost and maximum feasible speed, bearing in mind:
- the interactions and limitations of the grid and distribution system,
- the differing loads and patterns that different heating and other power demands may impose,
- considering the cost of various energy storage options,
- what building fabric improvements are cost-effective,
- the benefits and cost-effectiveness of interconnection
- dealing with a renewable non-availability dunkleflaute
- Impact of widespread electric car usage
Speakers this year:
1. Dr Alan Whitehead, MP. October 2016 – April 2020: Dr Alan Whitehead, MP. Shadow Minister for Energy Security. Speaking at 11.30.
2. Professor Mark Barrett UCL.Title – Modelling the least cost energy system for the UK Summary:
In the Green Light report (GL), Mark Barrett develops eleven 2050 net-zero system designs with variations of climate change, central and low demands, efficiency, heating shares and renewable generation. GL uses a model (ETSimpleMo) of the UK, without interconnector trading. The system capital, operational and fuel costs are calculated and the designs are optimised to find the least cost. The transition of capacities, operation, and costs between 2020 and 2050 is modelled.
(Note: The model uses an optimizer, a standard algorithm, that picks a mixture of all possible generating sources (wind, nuclear, solar, batteries, electrolytic hydroent etc) that will meet the loads, and finds the total cost of running that mixture against 30 years of half-hour weather data; the weather data also determining the heating and power load. At the same time various energy conservation measures, principally insulation etc for buildings are picked. The algorithm tries all possible combinations and iteratively arrives at the lowest-cost and lowest carbon solution. This is across all sectors, building, industry, maritime, aviation, and transport.-Ed)

3. Eric Lewis: Chief Engineer for Converteam, and then GE Power Conversion before starting a limited company trading as Enstore. Eric Lewis now mainly works as an external expert with NGESO particularly on the development of the “Grid Forming Grid Code”.
Summary: “How to stabilise, plan, control and operate the National Grid in a high renewable all electric future.”The author explains the various techniques and devices that can be used to ensure that a grid with close to 100% renewable sources can maintain stability. This entails replacing the present-generation large power stations which offer high inertia and ability to rapidly increase output by other electrical devices, some of which can use stored fuels such as renewable power generated hydrogen based fuels. This can be done at an affordable cost.
The presentation has data on why existing inverters are destabilizing the Grid and how GB grid-forming inverters solve this problem.
This includes data on why a limit on Grid Phase Jump Angle is now needed and how this could affect the Type Testing of all inverters connected to the Grid including existing and future renewable energy systems and HVDC systems. The presentation includes a new EITV method for calculating Grid stability and a GB Grid Forming inverter simulation model and examples of the technologies that can be used to stabilize, design, and control the Grid including the energy storage needed for a dunkelflaute weather event.
The presentation will come in two parts:
Part 1 on GB Grid Forming inverters and Part 2 on Stabilising, design and control of the GB Grid.

4. Christian Fabricius, Managing Director of SAV Systems & EnergiRaven Title: Heat Highways and Green Heat Grids. Lars, originally from Denmark, has spent most of his life in the UK. Since 1988 and with Lars at the helm, SAV Systems has been supplying best practice technology solutions from leading Danish technology partners to the Heat Network industry in the UK. Lars has contributed to many industry guidelines and has been a key campaigner for the expansion of Heat Networks in the UK. In 2022 Lars setup EnergiRaven. EnergiRaven’s purpose is to help eliminate energy waste through energy monitoring and system optimisation in commercial and multi-residential (communal heat network) buildings, as well as, a key focus on promoting Danish experiences, knowledge and best practice from their energy systems, most notably regional Heat Highways and Green Heat Grids. Summary The paper notes among other things the success of Danish DH in that 85% of dwellings are connected, that major pipelines are constructed to bring waste heat long distances to heat users, and that industry tends to cluster along this pipeline. It notes that DH is not confined to city centres as it is in UK, ( but without any valid reason being given – DA) and all suburban and village areas even at low density are considered feasible – anywhere where dwellings are clustered in fact.

5. Professor David Pearson– Summary: Aside from sharing the project details from Drammen, Queens Quay, Jarrow, Bristol and soon Liverpool, I’d probably take some time exploring how district heating can emerge to decarbonize high-density city areas and how heat pumps driven with renewable electricity offer a simple and proven way to achieve that……whilst identifying policy opportunities to make it happen quicker. 23-12-07.Large Heat Pumps in Cities.PEARSON.R0.dfp
6. Oliver – Martin-Du Pan– Energy Engineer, Geneva University Hospital Title: Novel gas engine applications with District Heat
Summary By 2035, there is a mandate to connect Geneva University Hospital to the GéniLac network, an ambient loop system, and to utilise locally an open-loop heat pump and to connect to it. To facilitate this, the hospital’s flow and return temperature of 165/100 ℃ will need to be reduced. In the interim, for the purpose of decarbonising the hospital, three CHP technologies are compared. After assessing the exergy alongside their energy efficiency, Scenario 2 is selected. Scenario 2 combines the use of a CHP engine and a high temperature heat pump to generate heat and power with respective efficiency of 47.3% and 28.3%, and an overall exergy efficiency of 45.4%. To save more primary energy and to provide grid support during peak demands, this paper emphasises the importance of employing decentralised energy and CHP technologies during this transition period. Finally, this paper suggests incorporating both energy and exergy efficiency calculation in Combined Heat and Power Quality Assurance standards. 231026 231026-PowerEx3pdf
7. Steve Harris, RIBA,Technical and Policy Director, Energence Ltd. 01873 852147 / 07958 992292. Title: Energy planning policy consulting and monitoring on behalf of Ealing Council Planning Services steve.harris@energence.co.uk & Adrian Hewitt adrian.hewitt@energence.co.uk is projects director at Energence Ltd. Synopsis: When a politician announces a renewable energy/CO2 reduction target – do you really think it is going to be met? When they then say their target is being achieved – do you believe them? How many renewable energy installations on the roofs of buildings do you think are actually switched on – or even installed? How can ambition match reality? Since 2013 Energence Ltd. has been working with Ealing Council, and (now) Greenwich, to set planning conditions that require all new building developments to meet hard energy/CO2 reduction targets – and then uniquely legally requiring them to fit Energence’s meters that send the kWh data to their Energy Monitoring Platform to confirm that they are achieving what they predicted they would in their planning application energy strategies. We have some stories of what actually happens when policy hits reality and how the powerful underused legal tool that is planning permission can be fully used to achieve energy policy targets Keeping zero carbon promises Dec 2023

10. Dr Fred Starr FIE, FIMMM, MIMechE, C.Eng. Hydrogen Fuelled CCGTs: The Back Up to Wind Power. Summary: This article falls into two parts. The first emphasizes that the cost of renewable hydrogen will limit its use in the domestic sector for home heating. As such, hydrogen’s almost certain use will be as a fuel for CCGTs that provide backup for wind energy. The second part of the article is a critical assessment of a recent ESO-National Grid paper which looked at the kind of backup for wind that would be in place in 2035.In the opinion of this author, the ESO paper makes a major mistake in thinking that much of the backup will come from imports and the so-called V2G power. This is where power from electrical cars flows back into the grid. If I am right, it follows that there will have to be much greater reliance on CCGTs fuelled by hydrogen and carbon capture-type CCGTs running on natural gasMIMA 3 Hydrogen – The backup to Windpower … Version 3
