Summary
In this episode of the Fully Charged Show Podcast, Imogen sits down with Ed Porter from @modoenergy one of the UK's leading experts on battery energy storage systems (BESS), to demystify the critical role batteries are already playing in balancing the grid — and what’s still to come. From frequency regulation and price arbitrage to blackouts and the path to clean power by 2030, we explore how grid-scale batteries are transforming our energy system faster than you think. Ed shares his insights on:
- Why batteries are replacing gas in grid services — and slashing costs.
- What dynamic frequency response actually means
- How the UK went from 0 to 5.3 GW of battery storage — and where we go from here
- Why the “1.5-hour” battery duration isn't a limitation, but a smart design choice
- How we plan to survive “Dunkelflaute” and keep the lights on in winter.

| 0:00.0 | Hello and welcome to another episode of the fully charged show podcast where today we're catching up with Ed Porter, Director of Insights for Europe of Modo Energy. Now, Modo Energy are the experts when it comes to understanding battery storage systems on the grid. |
| 0:23.5 | So in this conversation, we're going to talk about things like decoupling the cost of electricity from the price of gas, |
| 0:28.7 | the role of batteries for storing energy when it's abundant and releasing it when it's less abundant, |
| 0:33.9 | frequency regulation, the future of the grid, and loads of other tasty things as well. Of course, |
| 0:39.8 | this is a very, very complicated topic. So there are so many things that we didn't get a chance |
| 0:43.8 | to get into in any real detail. And I think it's only sensible to have a follow-up conversation |
| 0:48.7 | with Ed in the very near future. But please do let us know what you think. Let us know which |
| 0:53.1 | questions we didn't answer and any thoughts that you may have as well. Now, before we get into our conversation |
| 0:58.8 | with Ed, a very, very quick advert break. We've teamed up with Jurosell Energy to celebrate their |
| 1:04.5 | brilliant ecosystem of home energy products and their platinum home owner offer by giving |
| 1:09.8 | away a Juriselle bunny. To win, simply watch |
| 1:13.1 | to the end and answer a question about fully charged. Ed, thank you so much for joining us on the |
| 1:19.2 | podcast today. And your really wonderful set up there, which I know you used for your own podcast, |
| 1:24.0 | the transmission podcast. It's looking very fabulous. Yeah, well, Imogen, thank you for |
| 1:28.4 | having me. Honoured to be here. Now, I'm going to ask you to kick us off by explaining |
| 1:33.7 | exactly who you are, what Modo Energy is, and can you give me your dinner party response for the |
| 1:40.2 | people who have no idea about electricity or anything like that. |
| 1:44.9 | Okay, so at Modo Energy, essentially we track battery storage. |
| 1:49.3 | So how does it operate today? |
| 1:50.7 | We also forecast how it operates in the future. |
| 1:53.4 | And then we write research around that. |
| 1:55.8 | So if you were to own or to operate or to finance battery storage, |
