This Week in Storage: Aecon's 1,200 MWh Deal, InoBat's $1.27B Nasdaq SPAC, and Italy's Tolling Boom

GLOBAL — August 1, 2026 — As July closes and August begins, the energy storage industry delivered a week of transactions spanning North America, Europe, and the public markets. Here's your 4-minute Saturday briefing.

Canadian infrastructure giant Aecon Group executed an energy storage agreement for a 1,200 MWh BESS project in Ontario (July 30, Energy-Storage.News).

Ontario is emerging as one of North America's hottest storage markets, driven by the province's nuclear-heavy grid that needs fast-responding balancing resources. The 1,200 MWh scale signals that Canadian utilities are now procuring storage at the same magnitude as California and Texas.

The takeaway: North America's storage market is no longer a two-state story. Canada is scaling.

Slovakian battery and BESS manufacturer InoBat agreed to merge with SPAC Cartesian Growth Corporation II in a deal valuing the company at $1.265 billion (July 27, multiple sources). Shares will list on Nasdaq under ticker INBT, with closing targeted for late 2026.

InoBat — backed by Gotion High-Tech (which bought a 25% stake in 2023) — is Europe's most prominent independent BESS manufacturer. Its public listing provides a pure-play European storage stock at a time when investors are hungry for non-China battery exposure.

The takeaway: A European BESS manufacturer just proved it can command a billion-dollar valuation. The market for storage equities is deep and growing.

Swiss energy trader Axpo and Spanish developer Zelestra agreed on a 207 MW BESS tolling deal in Italy — Axpo's second Italian tolling agreement this month. Under a tolling structure, Axpo pays Zelestra a fixed fee for the right to operate and dispatch the battery, capturing all energy and ancillary service revenue.

Italy is rapidly becoming one of Europe's most attractive BESS markets due to its high wholesale price spreads, aging thermal fleet, and grid congestion that storage solves efficiently.

The takeaway: Tolling structures — where a third party pays for the right to operate your battery — are becoming mainstream. Asset owners who build storage don't need to be energy traders to profit.
