🎧 Transmission: Africa needs 100 GW of new capacity this decade. Battery storage is the fastest way to get there, but most of what outsiders think about these markets is wrong. Michael Cupit spent eight years getting a single project operational in Malawi.

France's solar capture rate fell from 97% of baseload price in 2022 to 60% in 2025. The CRE's new tender framework allows co-located batteries to charge from PV during negative-price hours. It shifts the problem from subsidy cost to developer incentive.

SPP's battery fleet hit 550 MW in December. The region queued 54 GW but only 1% built. Skeleton Creek's 252 MW shows the Surplus pathway works fast. Question is whether the new Consolidated Planning Process finally unclogs the remaining 53.5 GW.

Fun price spread for mid-afternoon in GB where the buy price is below the sale price for domestic supply. All I need is to find 90GWh or so and I’ll have made a million. Those evening peaks are also quite spicy, ideal for batteries 🔋🌶️

Spain's day-ahead market stayed calm during a 62% gas price spike, but the story doesn't end there. CCGTs rarely clear day-ahead but re-enter through technical restrictions needed for grid reliability, adding 78% of CCGT generation. Gas costs still reach consumers, just through a different channel.

NYISO capacity prices for four-hour battery storage jump from $248/kW-year in 2026 to $723/kW-year by 2049. But here's the trap: battery-specific revenue moves the opposite way. Accreditation factors degrade faster than headline prices rise.

Poland recorded over 300 hours of negative prices in 2025, more than double Great Britain's 149. Coal still sets marginal price, but solar's rapid growth is forcing thermal units to bid negative or shut down. Battery storage economics are shifting fast.

Great Britain. 21 GW of solar online. Battery revenues fell 84% on 8 July versus 3 July as solar hit record 14 GW. Solar capture rates projected to fall from 89% to 68% this decade. That cannibalisation is why CfDs were needed to sustain the 45 GW by 2030 target.

🎧 Transmission: Biomethane supplies just 1% of UK gas demand today. But could it reach 30% by 2050? In this episode, Future Biogas CEO Philipp Lukas explains how anaerobic digestion could turn organic waste into clean gas for industry, heating, and hard-to-decarbonise sectors.

NEM. Four-hour BESS is now the default investment choice. Two-hour projects return 6-8% IRR; four-hour systems hit 10-11.5%. Fleet average duration passed 2 hours in late 2025 and will exceed 3 hours by 2029. Falling capex premiums and compressing spreads explain the shift.

🎧 Transmission: Great Britain's largest battery just connected to the grid. But building it required far more than megawatts and megawatt-hours. Lisa MacKay, COO at Fidra Energy, shares what it takes to deliver storage at scale.

SPP's 151 GW interconnection queue just got redesigned. FERC approved the Consolidated Planning Process in March 2026, merging transmission planning and generator interconnection. SPP now identifies where capacity is needed, then invites bids. Faster path for stuck projects.

CAISO's battery fleet hit 15.7 GW in Q4 2025, with 1.24 GW added that quarter alone. SP15 (Southern California) now holds 77% of all capacity. Arizona projects are expanding outside state lines. Full breakdown of regional buildout patterns and pipeline activity.

🎧 Transmission: 80% of clean energy projects fail in development. Not because ideas are bad, but because the process is broken: sequential, fragmented, slow.

When we’re looking to reduce gas consumption. Here’s March for my PV, heat pump, battery system with no gas heating. Roughly, 40% reduction of grid load and no gas on site. Total gas reduction is higher as grid around 25% gas atm.

Poland. Capacity market payments for BESS collapsed 85% by 2025, yet the largest BESS auction on record cleared 5.1 GW. Developers are pivoting from capacity contracts to merchant revenues. Day-ahead arbitrage and ancillary services now drive the investment case.

NEM. Battery storage jumped from 2 GW to 5.6 GW in 2025. As BESS scales from 5% to nearly 40% of peak demand by 2028, the investment calculus is shifting fast. What does this mean for your project economics?

🎧 Transmission: Tax insurance is quietly enabling billion-dollar clean energy deals by transferring IRS risk from developers to insurers.
