$/MWh was up ~76% YoY

Couple of recent renewables observations First, MISO has come from behind to soundly take the lead on peak solar output from PJM. These are the two largest markets in North America, and interesting test cases given quite different geographic attributes compared to early movers CAISO and ERCOT 🔌💡

I'll take any chance to work Work It into a bit of wonky energy market design discussion (the GHG component of LMPs under EDAM) 🔌💡 www.gridstatus.io/insights/423...

Datacenter load growth has been top of mind, but the most rapid demand expansion over the last decade was in ERCOT's Far West Weather Zone This quadrupling of demand started before AI, and predates Texas' spurt of crypto growth. Instead, it's anchored in a traditional Texas industry: oil and gas 🔌💡

SPP's expanded over the the interconnection DC tie line with the first day-ahead market clear that includes SPP West (SWPW) Day one sees regular congestion spreads, with decent consistency in price impact across locations in the newly-RTO territory. Alt text has more #energysky

quick insights post on the PJM principles, a mixed bag of course, curious to see how PJM responds 🔌💡 www.gridstatus.io/insights/336...

PJM’s long-term load forecast saw values rise once again in 2026, but the new forecast is outpaced by 2025’s until the 2030s in both the summer and winter 🔌💡 insidelines.pjm.com/pjms-updated...

With winter in full swing, households across the country have dialed their thermostats up, but the fuels and technologies keeping homes warm vary widely by region. This is mostly driven by climate, historical prices, and year of industrialization/electrification 🔌💡

Stop me if you’re heard this one before: the PJM capacity auction cleared at the cap 🔌💡 www.gridstatus.io/insights/310...

ERCOT’s cutover to RTC+B systems went smoothly 🔌💡 We’ll be posting live updates on Grid Status Insights as we explore outcomes today and over the weekend. Through the morning peak we’ve already seen real-time AS prices remain far lower than their day-ahead spike www.gridstatus.io/insights/top...

New England and New York have new ties with Québec coming online over the next 6 months, but is the power there to support them? 🔌💡 Earlier this year we noticed that flows into the US, and particularly New York, had dropped off, years before the threat of tariffs blog.gridstatus.io/more-hqs-tha...

What started as a normal, unplanned outage may leave Midcontinent Independent System Operator (MISO) without 1.25 GW of nuclear generation for an extended period of time 🔌💡 Read more at Grid Status Insights: www.gridstatus.io/insights/280...

Part two of our Western Markets series went up at the end of last week 🔌💡 this time we focus on SPP West, the undecideds, Canada, and risks in the West blog.gridstatus.io/western-mark...

Like any event that changes daily routines, Halloween impacts load curves across the country Over the past 9 years, real-time load has underperformed almost all of PJM’s forecasts over the evening peak, precisely during prime trick-or-treating hours 🔌💡

New blog went out yesterday, part one of our look into the overhaul of western markets on the horizon 🔌💡 blog.gridstatus.io/western-mark... little 🧵

ISO-NE just became the first multi-state ISO to phase out coal, nearly two and a half years ahead of schedule 🔌💡 short 🧵

As PJM prepares its 2026 load outlook utility forecasts show a rapidly shifting landscape, with smaller zones predicting surging demand 🔌💡 A balancing question in play is whether large zones can continue to scale larger, or if small areas have the headroom to steal momentum in the datacenter race

A little teaser of our next product release: Grid Status Insights. Insights is a real-time feed of expert commentary on energy markets and the electric grid — straight from our team of talented analysts. If you’ve enjoyed our blogs or social posts, you’re going to love this. Stay tuned 🔌💡

We’re early in the process of rolling out a new app— Nodal Analysis. DM if you’d like to test it and share feedback 🔌💡 We built it with two key upgrades: 1. A new database that runs on-demand analysis of years of data in seconds 2. An enhanced process for organizing the metadata for 75k+ locations

It’s duck hunting season as California’s summer fades away and demand from batteries takes firm grasp of CAISO’s daily demand curves 🔌💡

Net load volatility is on the rise as SPP enters shoulder season 🔌💡 In decades past, the fall shoulder season left time for autumn fun like apple picking and the pumpkin patch. Today, new metrics like net load drive markets, and they can be most volatile when outages rise and weather varies

ERCOT load-watchers will know that many days this summer have had a strikingly flat peak load curve, driven by curtailment to avoid 4CP intervals. Less clear was just how much of the resulting forecast gap could be driven by extremely flexible crypto demand. It turns out the answer is a lot 🔌💡

New blog! This time on Thunderstorm Alerts in NYISO 🔌💡 TSAs are called when enough lightning strikes the Hudson Valley area in a short amount of time. This triggers line limits on the 345kV system flowing into NYC, to avoid conditions 1977 blackout conditions blog.gridstatus.io/breaking-dow... /1

As Hurricane Erin approached New England last week, a curious thing happened. Wind generation in the ISO plateaued well above forecasts, sitting around the same level through Thursday into Friday Wind was low onshore, and the MW level approximately matches Vineyard Wind's possible output 🔌💡

New blog! 🔌💡 Wildfire impacts are now a regular, if unwelcome guest during Northeastern summers, with smoke affecting both solar output and load patterns in New York and New England. blog.gridstatus.io/canadian-wil...

The Baltimore area (BGE) of PJM just entered load shedding 🔌💡

Wildfire smoke complicated NYISO’s BTM solar forecast this week, overforecasting by over 500 MW on Monday and underforecasting by 1,000 MW on Tuesday This miss was not even, downstate zones, home to >50% ofload, hewed more closely to the forecast, while upstate zones saw large swings 🔌💡

Yup, detailed at the bottom of this blog from last year blog.gridstatus.io/caiso-batter...

Another hot week across the eastern interconnection 🔌💡 ~5 markets look to beat last summer's peak, while 3 seem likely to exceed this summer's forecast peak You can track the outlook on our summer hazards dashboard: www.gridstatus.io/dashboards/e...

new blog! 🔌💡 Digging further into the PPL zone in PJM and capacity constraints in general blog.gridstatus.io/pjm-ppl-capa... a few notes: 🧵

PJM’s 2026/27 BRA cleared at the market cap across the entire RTO, signaling no end to Big Tech’s insatiable demand for datacenter power Look for a blog from us later this week on recent PPA action in PPL and PJM's tight capacity conditions. 🔌💡

ayyy DOM prices are lower in the 26/27 BRA than last year's auction! oh, wait, the entire RTO cleared at the cap 🥴 funny map from PJM 🔌💡

Google’s 670 MW hydroelectric PPA with existing Brookfield hydropower in PJM is a sign of the times. Also in the PPL zone, Amazon’s attempt to take Talen’s Susquehanna nuclear plant behind-the-meter has been in the news since last year Over 2.5 GW of data center PPAs signed in a single zone 🔌💡

During the June heatwave, behind-the-meter solar in New England shifted peak demand by 2 hours and nearly 3 GW. Without BTM solar, ISO-NE may have broken its nearly 20 year-old demand record, challenging assumptions about load growth in the region. 🔌💡

This week, a historic early-season heat wave means grids across the Eastern US and Canada will face record demand 🔌💡 With triple-digit heat indices from the Gulf of Maine to the Gulf of Mexico, here’s what we expect to see across the different grid operators this week:

We’re about to release a new Forecast Analysis app, and we're looking for users to test it out! If you have experience analyzing forecasts or enjoy beta testing new data tools, comment or shoot us a DM for the link 🔌💡 we've been using it to watch PJM's load forecasts for the heatwave next week

This week, CAISO broke its battery discharge record 2x, jumping more than 800 MW 🔌💡 As the battery fleet has grown, the seasonal operations shift has become more pronounced. From winter into summer, the morning discharge peak declines and the evening peak shifts later with a steeper ramps

ERCOT's 4CP season is in full swing with systemwide load set to push into the high 70 GWs this week 🔌💡 Already batteries shifted a peak interval as the 6/2 max is lower than 6/8's once storage load is factored in June 8th was a Sunday, showing that with growing demand, peaks can happen on any day

Tomorrow, Dominion, the epicenter of data center load growth in the US, is forecasted to smash its previous early-June load record by almost 2 GW. Already in 2025 the zone set a new all-time record, reaching 24.6 GW in January. This forecast peak would surpass the peak of 2022’s entire summer 🔌💡

And here's the whole blog! 🔌💡 blog.gridstatus.io/caiso-solar-...

Little sneak preview of what we're thinking about for a forthcoming blog, looking at CAISO load, batteries, and gas ramps on May 20th, the current record-holding battery discharge day in California 🔌💡

Put out a new blog earlier this week on the rise of solar in MISO and PJM - how it's impacting operations across the stack, why geographic diversity matters, and what looks like an uptick in emissions as coal rebounded in both markets 🔌💡 blog.gridstatus.io/pjm-miso-sol...

New blog looking at the first week of IESO's new nodal market in Ontario! 🔌💡 we also made a price map animation, looking at spreads from the first half of this week blog.gridstatus.io/one-week-of-...
