Megapack Demand Surges
The wave of orders underscores accelerating demand for grid-scale battery storage as utilities race to integrate renewable energy. Among the largest commitments is a multi-year agreement with NatPower, signed on June 23, to deploy more than 25 GWh of battery storage across Italy and the United Kingdom — one of the largest cross-border storage deals announced in Europe to date, according to Reuters. Tesla will supply its Megapack units and handle engineering, procurement, and construction, while also optimizing energy trading through its Autobidder platform. energiesmedia.com reuters.com
The initial phase covers five projects, with an ambition to scale beyond 100 GWh and a construction budget of $4 billion to $5 billion. NatPower and Tesla said revenue from the partnership could surpass $15 billion over 20 years. reuters.com
Tesla Home and Opticaster
Separately, Tesla on July 6 launched Tesla Home, a home energy management system powered by an AI engine called Opticaster that comes standard with every Powerwall. The software predicts household energy consumption and solar generation, then automatically shifts loads to off-peak hours, charges batteries when grid prices are low, and sells stored energy back during peak demand through virtual power plant programs. driveteslacanada.ca notateslaapp.com basenor.com
No additional hardware is required. Tesla Home connects existing Powerwall, solar panels, Solar Roof, and Wall Connector installations into a single coordinated system managed through the Tesla app. According to Tesla, Opticaster has accumulated over 100 million hours of operational experience across the Powerwall fleet. basenor.com
Energy Business Momentum
The announcements arrive as Tesla’s energy division posts strong growth. The company deployed 13.5 GWh of energy storage products in Q2 2026, up 40% year-over-year from 9.6 GWh and 53% sequentially from 8.8 GWh in Q1, according to Tesla’s official production report. The quarter represented Tesla’s second-largest deployment total ever, trailing only Q4 2025’s 14.2 GWh. Tesla plans to release full Q2 financial results on July 22. pv-magazine-usa.com stocktitan.net ir.tesla.com
