The US solar industry installed 7. 5 gigawatts direct current (GW dc) of capacity in Q2 2025, a 24% decline from Q2 2024 and a 28% decrease since Q1 2025. Solar accounted for 56% of all new electricity-generating capacity added to the US grid in the first half of 2025, with a total. . We expect 63 gigawatts (GW) of new utility-scale electric-generating capacity to be added to the U. power grid in 2025 in our latest Preliminary Monthly Electric Generator Inventory report. This amount represents an almost 30% increase from 2024 when 48. EIA's latest monthly “Electric Power Monthly” report (with data through November 30, 2025), once again. . Solar has become the largest renewable source of installed power capacity in the United States, surpassing wind after 27 consecutive months as the leading source of new grid additions, according to the Federal Energy Regulatory Commission (FERC).

The "Dog Days" of summer, from late July to late August, are traditionally linked with heat and heavy air. While the term describes sultry weather, power grids also face their own Dog Days. They were historically the period following the heliacal rising of the star system Sirius (known colloquially as the "Dog Star"), which Hellenistic astrology connected with heat, drought, sudden thunderstorms, lethargy, fever. . Dog Days, the phrase invokes the hottest, most stifling days of summer. Once blamed for stirring fever and unrest, this seasonal. . The solar industry has done a spectacular job lowering costs in the past three years, slashing per-watt costs in half. But that price freefall, driven by the massive scale-up of Chinese manufacturers, has put dozens, if not hundreds, of solar companies on the endangered list. Of the many recent solar startups, the MIT spin-off has been notable for playing its cards right.

What are Dog Days astrology?
The dog days or dog days of summer are the hot, sultry days of summer. They were historically the period following the heliacal rising of the star system Sirius (known colloquially as the "Dog Star"), which Hellenistic astrology connected with heat, drought, sudden thunderstorms, lethargy, fever, mad dogs, and bad luck.
Why does the Dog Star Rise before the Sun?
Around late July, the Dog Star rises in the eastern sky just before the sun. Ancient observers believed this alignment with the sun contributed to the extreme summer heat, thinking it intensified the season's already sweltering conditions.
When did the Dog Days start?
In antiquity, the dog days were usually reckoned from the appearance of Sirius around 19 July (Julian) to relieving rains and cool winds, although Hesiod seems to have counted the worst of summer as the days leading up to Sirius's reappearance.
Are the Dog Days still a thing?
The concept behind the dog days hasn't disappeared. While most of us aren't tracking Sirius at dawn, the phrase still captures the unmistakable feeling of late summer, when the air is heavy, energy dips and people instinctively seek out shade or air conditioning.
As part of their information disclosure regulations, Transpower and all 29 EDBs are required to report the duration, frequency, and causes of power outages. The duration and frequency of outages are normally expressed in (system average interruption duration index) and (system average interruption frequency index). In the five years to 31 March 2024, the 29 EDBs reported an average unplanned-outage SAIDI of 204.04 minutes and a SAIFI of 1.87, and an average planned-outage SAIDI of 101.16.
