Transmission

Most BESS revenue forecasts aren't wrong, they're just being used for the wrong thing. The gap between a valuation-grade forecast and what a project actually earns in a live market is where BESS developers win or lose. The developers who survive that gap are the ones who design for uncertainty from the start - not after the fact.
Recorded live at the Investing in Battery Energy Storage conference, Paul Mason, Chief Investment Officer of Harmony Energy, joins Ed Porter for a return appearance on Transmission.
They cover:
- Why treating a revenue forecast as a fixed cash flow is the most common mistake in BESS development.
- How the listed fund model enabled GB BESS to scale.
- Why splitting BESS revenues into ancillary, wholesale, and balancing mechanism streams is now a misleading framework.
- How Harmony selects new markets in France and Germany: renewable penetration, grid-first site selection, and why any business case dependent on high ancillary revenues is a losing strategy.
- What good optimizer relationships actually look like.

Battery storage in Africa is one of the most misunderstood opportunities in global energy. Only 8% of the continent’s hydro power has been tapped. In Malawi, just 14% of the population is connected to the grid. Africa needs to add an estimated 100 GW of capacity in the next decade and the fastest way is with renewables and storage. Michael Cupit develops BESS projects in Malawi and Kenya, and he’s spent years working inside the gap between how these markets look from the outside and how they actually operate on the ground.
In this episode of Transmission, Ed Porter sits down with Michael to break down the real risk picture in Sub-Saharan Africa: why mid-to-high-teen IRRs are the reality, how 20-year capacity payment contracts compare to merchant BESS in Europe, and what it actually takes to get a project from bare earth to operational - a journey that took eight years in Malawi.
They cover:
The two biggest misconceptions about doing business in Africa
How South Africa, Malawi, and Kenya's grids differ and where batteries fit in each
The role of DFIs, MIGA guarantees, and multilateral risk wrappers in making projects bankable
China's declining role in African infrastructure and what's replacing it
The O&M challenge: building operational capability from scratch in frontier markets
Why winning the argument for renewables means making the commercial case - not just the climate one

Biomethane currently supplies just 1% of UK gas demand. Could it reach 30% by 2050? Philipp Lukas, founder and CEO of Future Biogas, makes the case.
The UK uses around 700 terawatt hours of gas every year. Even as electrification reduces that to 150–250 TWh by 2050, the gas that remains will be harder than ever to replace. Industrial heat, steel, glass, shipping, aviation.
Biomethane, produced from organic waste and agricultural byproducts through anaerobic digestion, could supply 50–60 TWh of that demand. That's roughly 10 times what the UK produces today.
In this episode of Transmission, Ed speaks with Philipp Lukas, CEO of Future Biogas. Philipp explains how the technology works, why the gas grid is the biggest battery in the country, and why turning it off would be a mistake.

Eight in ten clean energy projects never make it through development. Not because of bad ideas, but because of how the process is run: sequential, analog, and fragmented across consultants, spreadsheets, and months of waiting.
In this episode of Transmission, Alejandro speaks with Stuart Pomeroy from Paces .Stuart breaks down exactly why the traditional development model fails, what a parallel workflow looks like in practice, and how compressing land, environmental, interconnection, and permitting work into a single ecosystem can cut development timelines by more than half.

Tax insurance helps clean energy projects manage the risk of the IRS challenging their tax credits - like the Investment Tax Credit (ITC), Production Tax Credit (PTC), or bonus depreciation. Instead of carrying that uncertainty, developers and investors can transfer it to insurers, adding confidence to project financing.
In this episode, Alejandro speaks with James Chenoweth Managing Director at Alliant Insurance Services, about how the market works and who’s using it. They also touch on the key areas of risk today, such as whether projects properly qualify for credits, potential recapture issues, and structuring above the project level, along with ongoing uncertainty around foreign ownership rules (FEOC), which are still awaiting clearer IRS guidance.
