demand Early Season Heat Stressed The Eastern Interconnection PJM, NYISO, ISO-NE, and IESO exceeded last summer's peak demand, and did so before July. With load climbing beyond forecast, we break down how each region responded and navigated this record-breaking early-season heat event.
ancillary services ERCOT's 4CP Summer Demand Roller Coaster Takes Off as Storage Flips Outcomes ERCOT's 4CP program is a bellwether for the shifting face of electricity demand and grid services. We explore the new landscape and how real-time data is key for managing the risk of escalating transmission charges.
batteries In CAISO, Solar Generation Jumps Again While Batteries Reshape Demand April 2025 saw another round of record solar and storage participation in CAISO. We’re taking a look at how these resources, on both sides of the meter, continue to reshape market dynamics across the Golden State.
batteries The Sun Also Rises in the Eastern Interconnection MISO and PJM have finally seen substantial solar growth over the past year, but this new generation resource is also affecting the existing stack, altering the operations of coal and gas.
IESO One Week of Data from Market Renewal in IESO From nodal spreads to capture rates, we’re taking a look at the first week of action and outcomes in Ontario’s new nodal market.
batteries Exploring extreme prices in ERCOT with Grid Status On 2/19/2025 a single location in ERCOT experienced all-time-high prices. What happened, and was the local battery, Rabbit Hill, able to capitalize on these extreme prices?
batteries Byte Blackouts: How large data center loads are surfacing new issues With continued rapid growth in data centers, PJM's demand ecosystem is changing, but the market's resource mix has yet to add its own flexible assets.
IESO Market Renewal in Ontario: Navigating IESO's Shift to a Nodal System Ontario's power market administrator, IESO, is about to undergo major changes. We explore the history of the ISO and examine the impact these reforms will have on participants.
congestion PJM's Peninsula Problem The Delmarva peninsula is penned in by geography with limited internal generation and strong demand. Managing transmission will be key as the region's fuel mix evolves.
ERCOT West Texas and Northern Virginia, Harbingers of Load Growth Prior to the current datacenter demand explosion, far west Texas in ERCOT and Dominion in PJM were already experiencing significant demand growth.
ISO-NE Tariffs Challenge the Interconnected Northeast New York and New England are heavily interconnected with the Canadian grid, importing cheaper and cleaner power than internal generation. Tariffs are driving uncertainty in both operations and planning.
batteries ERCOT is on a hot streak during a cold winter ERCOT set new records in load, net load, solar, prices, and battery discharge within a few days, let's explore the data.
ERCOT Batteries have Reshaped ERCOT’s Ancillary Services Procurement For most of their tenure on the ERCOT grid, batteries have largely made their bones supplying ancillary services as opposed to energy, but that is beginning to change.
ERCOT Winter is Here, its Risks are Growing As the first major winter storms of 2025 unfold, the unique risks of winter weather on the grid are coming into focus. Let’s explore winter's impact on the grid and how regions are adapting to these evolving challenges.
ERCOT Year in Review: Solar Generation in 2024 Tracking solar's growth across US markets and its contribution to peak demand in 2024.
PJM In Dominion, the needs of Data Centers Drive Demand Parsing Dominion Energy's place in PJM, now and into the future.
CAISO Peak Western Conditions Reveal a Changed CAISO On September 5th and 6th, 2024, the California ISO (CAISO) was under stress from both within and without. High temperatures, spiking day-ahead prices, import cuts, and wildfires — a problematic milieu. Despite this, real-time prices remained low and neither conservation calls nor emergency alerts made an appearance. Let's dig
