A trio of renewable-power stocks bought on the same thesis — that solar and storage projects would profit as electricity prices rise with data-center demand — fell an average of about 10.5% over the past month. That average, however, describes no single company. One of the three is up double digits and raising its spending plans; another missed on weather, not cash flow; and only the third is dealing with a real, policy-driven hit to its business.

XPLR Infrastructure, a yieldco spun out of NextEra Energy that owns long-term power contracts on wind, solar and Texas gas-pipeline assets, is up 15% over 90 days and nearly 29% over the past year. Its second-quarter adjusted earnings before interest, taxes, depreciation and amortization (EBITDA) came in at $523 million, the company fully repaid $500 million of convertible notes that had been an overhang, and it reaffirmed full-year EBITDA guidance of $1.75-1.95 billion. XPLR trades at 9x trailing earnings and under 1x sales — cheap, not de-rated.

Clearway Energy, which owns and operates a 13.6-gigawatt fleet of contracted wind, solar and gas plants across the country, is down 21% over 90 days, and its trend has genuinely flipped from a sustained uptrend to a sustained downtrend. But the cause is weather, not a broken business model: an El Niño pattern held wind output to 96% of plan and solar to 95% in the first half, pressuring near-term cash available for distribution. Management still reaffirmed full-year 2026 cash-available-for-distribution guidance of $470-510 million and actually raised its 2026-2029 capital-spending plan 20%, to $3 billion. One analyst note argues the stock is now roughly 24% undervalued ahead of its August 5 earnings report, which will confirm or break that guidance.

Sunrun, the largest U.S. residential solar and battery installer, which finances most systems through subscriptions rather than outright sales, is where the pain is real. The federal residential solar tax credit, known as Section 25D, expired entirely on January 1 with no phase-down, and Sunrun's first-quarter subscriber additions fell 25% year over year with installed capacity down 19% and cash generation negative $59 million. The company still guides to $250-450 million of full-year cash generation, and Jefferies argues Sunrun's subscription model could relatively benefit as owner-financed rivals lose the credit entirely — but the near-term numbers back the stock's 48% six-month decline.

Two adjacent names confirm the split rather than resolve it. Enphase Energy, which makes the microinverters and home batteries used in rooftop solar systems, saw revenue fall 19.6% year over year — a real deterioration matching its stock's decline. Brookfield Renewable, a global owner of hydro, wind, solar and battery assets, posted record quarterly funds from operations, up 11% per unit, and is barely down at all — its stock is following its own business, not the group.

The backdrop cuts both ways. The Energy Information Administration expects summer wholesale power prices to fall 8% this year on cheap gas, meaning the near-term "marginal price" catalyst these stocks were bought for hasn't shown up yet. But PJM capacity auction prices, a forward-looking signal of grid tightness from data-center demand, rose 833% year over year — the multi-year thesis remains intact even as 2026 spot prices disappoint.

On valuation: XPLR at 9x trailing earnings and Clearway at roughly 5x sales both sit well below levels that would price in a business break, and both have reaffirmed the guidance a reader can check against the tape. Sunrun's 0.75x sales multiple already reflects distress, leaving less room for further multiple compression even if subscriber growth stays weak.

The setup

Where it stands — XPLR is rising on reaffirmed guidance, Clearway fell on weather with cash-flow guidance intact, and only Sunrun shows a real policy-driven deceleration. Would confirm — Clearway's August 5 print holds $470-510 million CAFD guidance; Sunrun's subscriber adds keep falling below 2025 levels next two quarters. Would invalidate — Clearway cuts CAFD guidance below $470 million, or Sunrun's quarterly cash generation turns positive and subscriber adds stabilize. Watch next — Clearway Energy reports second-quarter results after market close on August 5, 2026. Valuation — XPLR trades at 9x trailing earnings versus its own multi-year range near lows; Clearway at ~5x sales versus a analyst-flagged 24% undervaluation into earnings.
