Commercial Battery Storage: Cutting Costs, Boosting Resilience, and What’s Next

Russell Reading is joined by clean tech consultant Tristan Dorman to break down why commercial battery storage is surging: covering energy price volatility, grid reliability, falling system costs, and maturing tech. They explore how batteries unlock value through self-consumption of solar, peak shaving, off‑peak arbitrage, and participation in flexibility/capacity markets, plus what businesses should evaluate before investing (including approvals and future load growth). The episode closes with a look ahead at batteries becoming “standard,” rising demand (including from AI/data centers), and improvements in battery chemistry and deployment models.

Why BESS Is Becoming Core Grid Infrastructure

In this episode, Russell and Kenny unpack the rapid rise of battery energy storage systems (BESS) and why they’ve moved from a niche technology to a foundational part of modern power grids. They explore how falling costs, policy signals, and real-world market examples like CAISO are reshaping grid reliability, developer strategies, and corporate energy procurement, while looking ahead to how storage value and contract structures will continue to evolve.

Corporate PPAs in Transition: From Volume to Value in a Changing European Market

On this episode of Renewable Roundup host Russell speaks with Lauren Stewart of Zeigo Network about corporate PPA trends across Europe from 2024–26. They discuss Spain’s surge in solar PPAs, Germany and the Nordics’ market dynamics, and cooling sentiment in 2025.
The conversation highlights a shift toward better‑designed deals—hybrids, baseload and shaped profiles—with examples like Merlin Properties’ long‑term solar deal and Airbus’ baseload PPA with TotalEnergies. Lauren explains how developers and buyers are adapting and where the market may head next.

On‑Site Solar: Opportunities, Obstacles & What Corporates Need to Know

Russell Reading interviews Pascal Olin from Alight about the growing value of on-site (behind‑the‑meter) solar and battery storage for corporates. They discuss how on-site systems offset rising non‑commodity costs, the role of BESS in increasing self‑consumption and tariff optimization, and why markets like the UK and Poland are hotspots.
The episode also covers practical steps to get started: building a business case, engaging stakeholders across procurement, finance and operations, running pilots, and scaling successful projects across sites and countries.

Next‑Gen IPP: How Sonnedix Is Shaping the Future of Renewable Energy

Russell interviews Gregorio Morales, Chief Commercial Officer of Sonnidex, about the company’s evolution into a next‑generation independent power producer. They discuss shifting from project-level sales to portfolio-based strategies, closer customer engagement, and advanced risk management.
The conversation covers practical plans—hybridizing assets with battery storage, building a trading desk, and offering flexible PPA structures tailored to customer needs across Spain, Portugal and Italy. Gregorio explains how these moves add customer value and create quality growth for Sonnidex.
They conclude by outlining the future vision: leading the market transition to resilient, decarbonized, customer-focused energy solutions that balance reliability, competitiveness, and flexibility.

Why Europe’s PPA Market Isn’t Keeping Pace, and What Must Change

Host Russell interviews Killian Daly, Executive Director at EnergyTag, on the widening gap between Europe’s renewable targets and the projects being developed, and how corporate power purchase agreements (PPAs) can help bridge it.
They cover market challenges like falling capture value, the case for firmed/hybrid PPAs with storage, government guarantees and aggregation, and how standardization and hourly matching rules could reshape corporate procurement and scale renewable investment.

Why Everyone’s Buying in ERCOT: A Candid Look at Corporate PPAs

This episode of Renewable Roundup explores North American corporate PPA trends in 2025. Russell Reading talks with Ethan Cox, a Zeigo Renewable Developer Account Manager, about the dominance of ERCOT (Texas) capturing around 50% of corporate PPA megawatts, the sharp decline in wind deals to about 6.5%, and the factors driving those shifts—land availability, regulatory and permitting hurdles, tariffs, and tax-credit changes.
They also discuss the outsized influence of hyperscalers (Google, Meta, Microsoft, Amazon), which accounted for the majority of corporate PPAs, how non-hyperscalers chase the best-priced deals often in ERCOT, and how potential GHG protocol guidance could push buyers to source closer to load.
The episode closes with observations on pricing trends, the recent “gold rush” for projects before policy changes, and uncertainty around future price impacts as tax credits and regulations evolve.
