As Tesla prepares to report its quarterly results, all eyes are shifting away from its electric vehicle lineup and toward the division quietly holding the company together. According to Reuters, Tesla's solar and energy storage business is poised to outperform the automaker's struggling core Electric Vehicle (EV) segment, offering a rare bright spot as the company navigates shrinking vehicle margins and a turbulent policy environment.

For enterprise technology and infrastructure leaders, the signal matters as the same large-scale battery storage systems propping up Tesla's balance sheet are the ones powering the data centres your organisations increasingly depend on.

Tesla Energy Growth Cushions Regulatory Credit Decline

Tesla's vehicle profitability has deteriorated significantly from its peak. High-margin regulatory credits which was once a dependable profit driver have declined sharply following policy changes under the President Donald Trump's administration. The combined pressure of eroding automotive margins and a regulatory credit cliff is pushing Tesla toward its first quarter of negative cash flow in two years.

CEO Elon Musk's plans to build new assembly lines and scale humanoid robot production are projected to cost $20 billion in 2026 alone which is a significant capital commitment against a backdrop of weakening core revenue.

The energy division is stepping in to cushion that . Fuelled by surging enterprise demand for large-scale battery systems to power AI infrastructure and data centres, the business is growing faster and generating roughly twice the profitability of Tesla's ageing vehicle lineup. Wall Street forecasts energy revenue reaching approximately $18.3 billion in 2026, up from $12.8 billion in 2025, with gross profit climbing to around $5.3 billion and margins holding near 29 per cent. Industry analysts caution that the offset has limits. According to Reuters, Adrian Balfour, founder and chairman of advisory firm Envorso says:

Energy storage is cushioning the but not yet large enough to fully offset the combined pressure from both the credit cliff and automotive margin erosion. The trajectory is encouraging; the current magnitude is still insufficient.

How Tesla Megapack Is Powering Enterprise Data Centres

For CISOs and technology leaders building resilient infrastructure, Tesla's energy trajectory has practical implications beyond the stock market. The company is expanding Megapack and solar manufacturing capacity specifically to meet surging demand from hyperscalers and enterprise data centre operators which are the same facilities that underpin cloud services, AI workloads, and critical digital infrastructure.

Energy storage revenue is expected to account for roughly one-fifth of Tesla's total projected revenue in 2026, a major shift for a company whose $1.5 trillion valuation has historically rested on future bets of robotaxis, fully autonomous vehicles, and humanoid robots; none of which are yet commercially mature.

As reported by Reuters, Matt Britzman, senior equity analyst at Hargreaves Lansdown, noted that energy storage remains an inherently unpredictable revenue stream: 

That tends to be a lumpy business, so it is hard to read too much into it until we get more detail on the next earnings call.

For enterprise buyers, that variability is a procurement consideration. As Tesla scales its energy infrastructure ambitions, organisations with large data centre footprints should monitor both supply availability and the downstream implications of Tesla's capital priorities shifting between energy, robotics, and autonomy over the next 12 to 24 months.
