Gore Street Capital is a London-based investment manager focused exclusively on battery energy storage. Founded over a decade ago, the firm manages over £650m million in assets and operates one of the most geographically diverse battery portfolios of any specialist investor. Its flagship fund, Gore Street Energy Storage Fund PLC (LSE: GSF), has operational assets across five grids — Great Britain, the Island of Ireland, Germany, Texas (ERCOT), and California (CAISO) — spanning 32 investments. The firm recently completed the first close of a new European energy storage fund, initially targeting Poland, Germany, Spain, and Ireland, and launched Japan's first dedicated energy storage fund.

Gore Street's in-house commercial team manages everything from market research to algorithmic trading — giving it unusual operational control for a fund manager.

"We got into batteries about 10 years ago and we've been expanding globally since then," said Alan, Principal at Gore Street Capital. "We see ourselves as specialists in the battery market, helping the transition to net zero."

The challenge: Five markets, one small team

Battery storage revenue depends on variables that differ fundamentally from market to market — grid codes, capacity mechanisms, subsidy schemes, and regulatory frameworks all vary across every geography Gore Street operates in. What drives revenue in Great Britain has little correlation with what works in ERCOT, and markets move fast.

For Gore Street's commercial team of six, staying on top of all of this is the central challenge.

"We're active in five different geographies, and with a small team, it's difficult to keep on top of all the changes and make sure we're extracting all the value we can," said Alan.

Each analyst specialises in specific markets — Priya Adinamozhi, Commercial Associate, focuses on the US, while colleagues cover GB, Ireland, and Germany. But when major projects arise, particularly the new European fund, everyone gets involved.

The Solution: One platform for a global portfolio

Daily benchmarking across five markets

Every morning, Gore Street's commercial team opens the Modo Energy Terminal. Each analyst has bookmarked the indices most relevant to their markets and checks how Gore Street's sites performed relative to the wider fleet.

"We come into work and want to check the performance of our sites every day," said Priya. "We've all bookmarked the indices we're most interested in — we want to see what batteries achieved and benchmark ourselves against that."

Gore Street runs its own in-house optimization and algorithmic trading in GB and ERCOT — a rare capability among battery fund managers. An independent benchmark is critical.

Gore Street runs its own in-house optimization and algorithmic trading in GB and ERCOT — a rare capability among battery fund managers. An independent benchmark is critical.

"I look at the Modo Energy Terminal daily — what other people are doing with their assets, how my performance compares to the fleet," said Alan. "We're constantly figuring out what we could do differently, what we're doing well, what we might change."

Without the Terminal, the alternative is fragmented — logging into individual optimizer platforms, navigating grid operator websites, and searching for competitor data across energy news sites.

"It's the difference between looking at our own assets in isolation versus assessing our fleet against the market," said Priya. "The Terminal has it all in one place."

Research that sharpens internal analysis

Gore Street does substantial in-house research — analysing historical revenues, tracking price peaks, and forming views on where each market is heading. Modo Energy's research serves as both validation and a source of new insight.

"We either agree with Modo Energy, or we challenge their opinion," said Priya. "If we disagree, we ask — why? What data are they using? If we agree, we ask the same questions. Both are valuable."

When Modo Energy published analysis showing that ERCOT's West Hub achieves better price spreads — a finding aligned with Gore Street's own data — the team could cite it with confidence. When Modo Energy published data on declining interconnector applications in ERCOT in late 2025, it prompted the team to reconsider assumptions about battery demand in Texas.

"That interconnector data shaped our long-term view," said Priya. "Seeing Modo Energy's analysis made me think — maybe there's a downward trend in the build-out case for Texas."

"Even when we do our own research, it tends to point us back towards Modo Energy," said Alan. "We know we can go there and see professionals who know what they're talking about, explaining a situation clearly."

An independent source that stakeholders trust

Gore Street uses Modo Energy's data not just internally, but in conversations with optimizers, at industry conferences, and in board-level reporting. Modo Energy's independence — no affiliation with any optimizer, developer, or fund — gives its data a credibility that internal analysis alone cannot match.

"Modo Energy is one of those names that everyone knows," said Priya. "You can talk to someone at a conference and say — this is what Modo Energy published. What do you think?"

"An independent view of market performance is essential," said Alan. "We run our own trading, and I need to show our investors that we're getting the most out of our assets."

Accelerating new market entry

As Gore Street expands into European markets through its GSE fund, Modo Energy is directly supporting due diligence. The Modo Energy team has visited Gore Street's offices to present on markets including Italy, France, and Germany.

"Five of the Modo Energy team came in and presented on Italy, France, Germany," said Priya. "That directly supports our new market research."

A Modo Energy article on Spanish battery storage optimizers gave Gore Street a shortlist of potential partners — saving significant time on manual research.

"Modo Energy published an article on Spanish BESS optimizers, and we reached out to all of them," said Priya. "It would have taken much longer to find them otherwise."

Getting new analysts up to speed — fast

When Priya joined Gore Street, she was new to battery storage. Modo Energy's podcasts, Energy Academy, and research library became her primary onboarding resource.

"I was completely new to the industry," said Priya. "I went through the ERCOT podcasts in half a day, and within a week I'd caught up on the basics of every market we operate in. Without Modo Energy, that would have taken two to three weeks longer."

Alan sees this as a strategic advantage: "New joiners don't necessarily have experience in batteries. We point them towards Modo Energy's articles and they get a head start into how the different markets work."

The impact: Faster decisions with more confidence

Modo Energy feeds into Gore Street's daily operations across five markets — from morning benchmarks to optimizer accountability to research for new fund launches. For a team of six managing a global portfolio, it is infrastructure.

When Gore Street needed to decide whether to register its GB assets in the Balancing Mechanism, the Terminal provided the data.

"We could see what other assets were doing, what decisions they'd made, and how well it was working for them," said Alan. "That was a key input in how we registered our assets."

Going further and faster together

Gore Street's vision is to build battery storage globally. With a new European fund and a Japan fund making its first acquisitions, the geographic footprint is set to widen — with Modo Energy supporting the expansion.

"As we expand into new geographies, having independent data sources is critical," said Alan. "Modo Energy is a company we're very comfortable with. Expanding into new territories together is something we're keen to do."

"We look forward to Modo Energy updating the Terminal with benchmarks, indices, research, and podcasts for new markets," said Priya. "Helping us understand how these market structures work."

And when asked what she would tell a peer considering Modo Energy, Priya was direct: "If you're in this industry and you don't use Modo Energy, you're missing a trick. Modo Energy has become the Bloomberg for batteries. You can access great research, benchmark yourself against the market and see how competitors are performing.”
