Renewable Energy
Generation is no longer the hard part. Solar and wind are the cheapest new capacity in most markets, and in 2026 they make up the overwhelming majority of what actually connects to grids — around 79 GW of the 86 GW being added in the United States alone.
The hard parts have moved downstream: what the power is worth when everyone generates at the same moment, whether the wires exist to move it, and how much firm capacity a variable resource can be credited with. BrightVolt covers wind, solar, hydro, grids and home electrification with those questions in front.
System Strength: The Grid Service Inverters Can’t Fully Fake
As grids fill with wind and solar they run short of system strength – the fault current that lets protection sense a fault. Why it happens, and why the fix is often a machine that generates nothing.
Alberta’s $14 Solar Panel Recycling Fee Starts Oct 1
From October 1, Alberta charges C$14 to recycle every new solar panel and bans them from landfill. The industry backs recycling but calls the fee a punitive tax set with math it won’t show.
Electrified Homes Shield UK Bills – but Not Evenly
Ember says an electrified home – solar, battery, heat pump, EV – is ten times better shielded from price shocks. Its own numbers reveal a shield bought upfront, and a widening gap with homes that can’t.
Scarcity Pricing and the ORDC, Explained
In an energy-only grid like Texas, no plant is paid just to exist. Scarcity pricing does that job: the ORDC adder lifts real-time power prices as reserves run low, toward a $5,000/MWh cap. Here is the mechanism.
The BrightVolt Take: The VPP Dispatch That Beat Our Forecast
Sunrun and Tesla dispatched a record 580 MW from 140,000 home batteries. A month ago we pegged that fleet’s real output at 300 MW. We were too cautious – but 16.8 GW is still wrong.
Energy-Only vs Capacity Markets: What Each Rewards
An energy-only market pays a plant only for the power it makes; a capacity market pays it again, years ahead, just to stay available — the design choice behind Texas’s battery boom.
Renewable Curtailment: Why Grids Throw Away Clean Power
Curtailment is a grid deliberately spilling wind and solar it could have used. Why it happens, why the official rate can be a third of the real one, and how grids stop wasting it.
US Solar Modules Hit 100 GW. The Cells Are Imported
The US has built 100 GW of solar modules, most of it since the IRA. But module assembly is the easy step, and domestic cell capacity sits near 3 GW against 65 GW of module lines.
The BrightVolt Take: How Texas Out-Built California on Batteries
Texas has more grid batteries than California and built them faster, with no storage mandate and no capacity market. The lesson isn’t politics. It’s market design.
