Enhanced Geothermal Systems Explained: Fervo and the Tech Behind Deep Drilling Geothermal

In my latest episode, I break down the following key details from the project updates and industry filings: Fervo's 33 MW Launch at Cape Station: Fervo Energy has begun producing 33 MW from its first commercial project in Cape Station, Utah under a Power Purchase Agreement (PPA) with Shell Energy. Phase one consists of three 33 MW "GeoBlocks" (with the remaining two expected by year-end), an additional 400 MW under construction for 2028, and environmental permits allowing expansion up to 2,000 MW. Hydrothermal vs. Hot Dry Rock: Traditional hydrothermal systems (such as The Geysers in Northern California, which dropped from 1,875 MW to ~900 MW due to steam depletion) rely on rare natural underground water reservoirs. Next-gen geothermal drills 3 to 4 miles deep into 400°F–450°F granite lacking natural water. Advanced (Closed-Loop) vs. Enhanced (Fracked) Systems: Advanced geothermal (such as Eavor’s project in Geretsried, Germany) uses closed-loop underground pipe "radiators," but faces complex lateral drilling challenges (connecting 6 of 12 planned lateral pairs). Enhanced geothermal (used by Fervo) utilizes parallel well pairs, cemented steel casing, perforating guns, and multistage hydraulic fracturing to open micro-fissures directly in the granite. Water Recapture & Heat Exchange: Fervo circulates degraded water (such as saline or agricultural runoff) through rock micro-fissures to absorb heat, bringing superheated water to the surface to vaporize a secondary working fluid in a closed loop. Fervo reports an 80% to 90% water recapture rate. Commercial Offtake & Pricing: Major PPA deals include Fervo’s 396 MW contract with Google, 320 MW with Southern California Edison, and a publicly filed 115 MW Clean Transition Tariff contract with NV Energy priced at $107 per megawatt-hour . Houston Geothermal Ecosystem: Over a dozen advanced and enhanced geothermal startups are leveraging Houston's oil and gas fracking expertise, including Sage Geosystems (partnering with Ormat on a 150 MW deal with Meta) and XGS Energy. Geographic Constraints: U.S. Geological Survey mapping shows suitable hot rock at 1.5 to 3 miles depth in the Western U.S. versus 5 to 8 miles depth in the Eastern U.S., meaning near-term development will remain concentrated west of the Continental Divide.

Optimizing Our Transmission System

In this episode, I examine the U.S. Department of Energy’s $1.9 billion SPARK initiative funding 31 grid-improvement projects across 26 states, and explain how Alternative Transmission Technologies (ATTs) and Grid Enhancing Technologies (GETs) can unlock significant grid capacity without waiting decades for new transmission lines. Here are the key topics and technologies I break down in today's video: The Transmission Permitting Bottleneck: Why building new transmission lines takes over a decade—highlighting the 3,600 MW SunZia wind transmission line, which took 17 years from permitting to first power—and why a recent study showed only ~15 miles of high-voltage transmission built in the U.S. between 2022 and 2024. The DOE SPARK Initiative: How $1.9 billion in federal funding (catalyzing an additional $3.35 billion in recipient cost-sharing) aims to make 23 gigawatts (23,000 MW) of additional transmission capability available across existing rights-of-way. FERC Regulatory Mandates (Order 2023 & Order 1920): How FERC Order 1920 shifted from merely encouraging grid operators to requiring them to evaluate and document cost-effective GETs before receiving approval to build new interstate transmission. Advanced Re-conductoring: Replacing old ACSR (aluminum conductor steel reinforced) wires with lighter, trapezoidal composite-core conductors that can double line capacity on existing towers at less than half the cost of new lines. Dynamic Line Ratings (DLR): How sensors and software monitor real-time wind and temperature conditions—acting like "an MRI on your wires"—to allow significantly higher power flows during cooler or windier periods. Topology Flow Optimization: How grid operators like MISO and SPP use software to switch breakers and redirect electron traffic around bottlenecks—acting as "Waze for the power grid" to reduce congestion costs. Advanced Power Flow Controls: Adjusting line characteristics and injecting reactive power to push electricity off overloaded lines onto underutilized capacity.

How PG&E’s SHARE Virtual Power Plant Turns Homes Into Grid Support

In this episode, I break down Pacific Gas & Electric’s (PG&E) announcement of a new Virtual Power Plant (VPP) called SHARE (Smart Home Assets for Reliability and Efficiency). I examine why Google is funding the program and what this initiative reveals about grid-edge capacity arbitrage and AI data center growth. Here are the key points covered in today's analysis: The SHARE VPP Structure: PG&E is collaborating with Rewiring America, Carrier, Tesla, Sunrun, Renew Home, Demand Side Analytics, Encoord, and Google. Starting in fall 2026, the program plans to enroll approximately 21,000 flexible energy devices totaling about 12 MW to shift peak demand away from high-stress periods. Carrier Heat Pump Subsidies: Single-family home participants in Alameda and Santa Clara counties with central AC are eligible for Carrier battery-enabled heat pumps with a $5,000 discount, with the first 25 households receiving twice that incentive. Google's Funding & Capacity Arbitrage: Google is covering all program costs, customer incentives, and heat pump subsidies. This setup serves as a model for capacity arbitrage, where tech companies pay to free up capacity on the grid edge that can subsequently be claimed to connect additional data load sooner. The Economics of AI Data Centers: Compute leases for AI data centers operate in a unique economic tier—with Crusoe leasing compute at roughly $1.25 billion per month per gigawatt and BloombergNEF estimating revenue around $1.76 billion per month per gigawatt. This provides strong economic rationale to pay for grid-edge capacity to get online faster. Grid-Edge Arbitrage vs. Data Center Flexibility: While data centers are also testing operational flexibility to reduce load during peak hours, neither grid-edge demand response arbitrage nor data center operational flexibility has been fully proven at gigawatt scale yet.

PJM’s New IRAS Filing: How Grid Operators Plan to Regulate Large Data Center Loads

In this episode, I break down PJM's recent filing to the Federal Energy Regulatory Commission (FERC) for an Interim Resource Adequacy Service (IRAS) . As massive new data center loads exert a tremendous pull on grid reliability, power quality, and energy prices, this interim proposal represents a major new regulatory mechanism to manage large electrical loads . Here are the key details from the proposal that I analyze in this video: The Scale of the Problem: Out of 32 gigawatts of forecasted demand growth in PJM between 2024 and 2030, a massive 30 gigawatts of that growth is driven by data centers . What is IRAS? PJM’s proposed Interim Resource Adequacy Service focuses specifically on new Large Load customers (primarily data centers) that do not provide their own power supply . The Emergency Shedding Protocol: Under IRAS, during periods of high grid stress, PJM would initiate an emergency notification procedure . This signals utilities to reduce or transfer the electricity demand of these new large loads before calling on standard demand response resources or proceeding to rotating blackouts . The "Build, Bring, or Buy" Standard: Large loads that do not bring new capacity or cover their demand through the upcoming Reliability Backstop Procurement will be subject to IRAS . This matches the White House Ratepayer Protection Pledge to "build, bring, or buy" the generation resources needed to satisfy new energy demands . The Large Load Registry: PJM plans to maintain a registry to track large loads and furnish information to state regulators and utilities . This allows state-level entities to manage retail load reduction and cost allocation while PJM retains the tools needed to handle grid reliability . Emergency Demand Reductions: If utilities do not acquire capacity equal to or above the combined peak demand of these new large loads, PJM would direct those specific zones to reduce demand proportionally during emergencies . Large loads may also waive compensation for cutting demand to protect ratepayers from rising bills . The 2029/2030 Capacity Auction Shift: Starting in December with the 2029/2030 base residual capacity auctions, new large loads that arrive without the necessary power supply won't be included as demand when future power needs are calculated . The Ratepayer Cost Impact: Over the last four capacity auctions (mid-2025 to mid-2029), PJM's capacity charges totaled over $63 billion . The Independent Market Monitor calculated that data loads drove up capacity costs by $29.4 billion—accounting for approximately 46% of total capacity payments . Most of these data loads are currently only projected rather than actually built . This December's auction results will give us a clear look at how data loads continue to impact ratepayer costs .

Texas Grid Collision: ERCOT’s Batch Zero & Governor Abbott's Data Center Audit

In this episode, I break down three major developments on the Texas electric grid that are rapidly changing the landscape for large-power interconnections. Here is what I unpack in today's analysis: What is "Batch Zero"? I explain ERCOT's new vetting process requiring large load applicants over 75 MW (primarily data centers) to meet strict criteria before they can interconnect. To proceed, applicants must prove site control, show financial capability, submit an initial qualifying study, and pay a fee of $50,000 per megawatt of load. The 500 GW Queue Reality Check: While ERCOT's interconnection queue recently reached a massive 500 GW , 294 GW was disqualified for failing to provide required details, leaving approximately 205 GW eligible for the Batch Zero study. Governor Abbott's Mandate & The Regulatory Pause: I detail Texas Governor Greg Abbott’s directive ordering ERCOT and the PUC to audit all prospective data centers for their water and power consumption, alongside any tax benefits received, due to concerns about grid reliability. ERCOT's "Good Cause Exception" Request: I discuss ERCOT's subsequent request to slow down the Batch Zero timeline while addressing these audit requirements, as well as their ask to continue processing 23 specific large-load projects to hold their place in line. Market & Political Implications: I look at Bloomberg New Energy Finance’s estimate that this regulatory pause puts 20% of the U.S. data center pipeline at risk . Finally, I touch on how data center regulation is quickly evolving into a bipartisan issue across the country.

The Texas Power Paradox

On July 2nd, the Texas power grid did something extraordinary: it shattered its all-time record peak, surging past 91,000 megawatts (91 GW). Even more surprising? ERCOT kept the lights on and prices remarkably low, all while adding almost no new fossil fuel capacity. But as demand continues to skyrocket, is this grid stability a sustainable reality or a temporary dream? In this episode, we go behind the scenes of the ERCOT dashboard to analyze exactly how Texas is surviving the summer heat, the secret weapon keeping wholesale prices in the $20 range, and the massive hurdles looming on the horizon. What We Cover: The 91 GW Record Smasher: Breaking down the massive July 2nd peak and how ERCOT managed the load without traditional fossil fuel additions. The "Cowboy Hat" Grid: A look at the state's unique supply mix, where wind energy forms the nighttime brim and solar power makes up the midday crown. The Battery Arbitrage Revolution: How Texas's rapidly growing battery fleet absorbs up to 8.5 GW of solar power in the morning and injects nearly 10 GW back into the grid during the crucial 7 PM to 11 PM evening peak. Why Gas Generators are Struggling: How cheap solar and battery arbitrage are making it incredibly difficult for new dispatchable gas-fired plants to turn a profit. The AI Data Center Threat & The $33B Battle: A look at Governor Abbott's recent directive to audit data centers for water and power usage, and the fierce political battle over the proposed $33 billion Permian Basin transmission expansion.

Why is the EV battery revolution still stuck on the runway?

I have a confession to make: my past predictions about Vehicle-to-Grid (V2G) and Vehicle-to-Everything (V2X) technology have been way too optimistic. Theoretically, the opportunity is massive. We have gigawatt-hours of batteries on wheels sitting idle in driveways more than 95% of the time. In fact, right now in the United States, there are over 250,000 bidirectional-capable GM electric vehicles on the road. At 10 kW of export capacity each, that is 25 megawatts of nameplate capacity sitting on wheels at a time when data centers are fighting over every single kilowatt of grid capacity. So, why are personal EVs still completely locked out of the grid-scale energy transition? In my latest episode, I dive deep into the real-world barriers holding this technology back—and the simple truth of what utilities are doing wrong.

The $29 Billion Power Bill: Inside PJM’s Capacity Shortfall

The power grid is hitting its limits. In this episode, we break down the critical results of PJM’s capacity auction for the 2028/2029 delivery year, where the price cap of $325 per megawatt-day was hit for the third consecutive auction. We examine the widening gap between skyrocketing electricity demand and lagging supply, and what this means for future grid reliability. Key Topics Covered: The 6,830 MW Shortfall: Discover why PJM cleared 149,181 MW of capacity, falling significantly short of its desired 20% reserve margin and leaving the grid at a tight 15% margin under worst-case scenarios. The Data Center Cost Explosion: Actual and forecasted data center loads have added a staggering 6.3 billiontothisauctionalone , makingup 4629.4 billion) of all capacity-related charges over the last four auctions—costs that ultimately fall on everyday ratepayers. The $555 Simulated Reality: Learn why PJM's simulated auction shows that without the current price cap, prices would have soared to $555/MW-day across most markets, and reached nearly $777/MW-day in the Chicago area. Why New Generation is Sitting Out: We look at why only 525 MW of new supply cleared. Skyrocketing costs for gas turbines—which are up 15% in a single year and 50% over the last five years—combined with manufacturers being sold out through 2030, mean developers are struggling to build new generation. The September Backstop Auction Loophole: We explain how developers might be bypassing the main auction to wait for September's Reliability Backstop Procurement (RBP) auction, which offers longer contracts (2 to 15 years) and a higher average price cap of $555. The Order 2222 Mystery: We discuss the surprisingly low turnout of demand response and why absolutely zero aggregated distributed energy resources (DERs) showed up to the party, despite being eligible to participate for the first time. As FERC Chair Laura Swett warns that this consecutive shortfall is an "alarm bell" for the industry, we ask the tough question: Is PJM’s complex system of price caps and regulatory patches sustainable, or are we heading toward a Texas-style market with no capacity guarantees at all?

Inside PJM’s $555/MW-day Reliability Backstop Plan for Data Centers

In this episode, we dive into the labyrinth of PJM's latest regulatory moves to address the insatiable electricity demand from data centers and the looming generation supply shortfall. We break down the newly approved Reliability Backstop Procurement (RBP) plan , which will allow utilities and large loads to secure capacity directly from suppliers through a one-time bilateral auction starting in the 2028-2029 delivery year. Key topics covered in this video: The New Auction Rules: Learn how load-serving entities will secure contracts spanning 2 to 15 years with a volume-weighted price cap set at $555 per megawatt-day . The Price Jump: Discover why this new price cap is considerably higher than the current $325/MW-day limit, and how the sequential auction formula is designed to keep generators from getting too greedy and gaining immense leverage. The Supply Chain Reality Check: We explore PJM's recent white paper, "Powering Reliability Through Market Design," which reveals that the estimated Cost of New Entry (CONE) for new gas-fired turbines has nearly doubled due to overwhelmed global supply chains. The Risk of Capital Flight: Could capping prices at $555 simply push energy developers to invest in supply resources in other states or countries with better revenue opportunities? The Future of Energy Markets: We discuss whether this crisis will eventually push PJM toward a Texas-style approach with no capacity market at all, and examine the irony of calling today's highly complex energy landscape "deregulated" Support the show 🎙️ About Energy Future: Powering Tomorrow’s Cleaner World Hosted by Peter Kelly-Detwiler , Energy Future explores the trends, technologies, and policies driving the global clean-energy transition — from the U.S. grid and renewable markets to advanced nuclear, fusion, and EV innovation. 💡 Stay Connected Subscribe wherever you listen — including Spotify , Apple Podcasts , Amazon Music , and YouTube . 🌎 Learn More Visit peterkellydetwiler.com for weekly market insights, in-depth articles, and energy analysis.

FERC Issues Show Cause Orders to Six Regional Grid Operators

The unprecedented rise of AI and massive data centers is putting severe strain on the electric grid, prompting a major regulatory crackdown . Large loads pose a unique threat because they are huge (sometimes requiring gigawatts of power), desperate for quick interconnection, and highly unpredictable due to the prevalence of "phantom loads"—projected facilities that sit in interconnection queues but may never actually be built . Furthermore, these large language model operations can physically destabilize the grid by interfering with the 60-hertz sine wave and abruptly snapping offline during minor power quality fluctuations, which has already caused over-frequency events . To bring order to this chaotic "land rush" for power, the Federal Energy Regulatory Commission (FERC) has issued a show cause order under Section 206 of the Federal Power Act . The directive targets six major regional grid operators: PJM, MISO, SPP, CAISO, ISO-NE, and NYISO . Finding that current tariffs are likely "unjust and unreasonable," FERC is demanding that grid operators either justify their existing rules or file reforms within 60 days . FERC requires the grid operators to address five specific categories of reform: Developing more efficient transmission study processes and evaluating Grid Enhancing Technologies (GETs) to maximize existing grid capacity without waiting for multi-year physical upgrades . Providing greater cost transparency to ensure the massive infrastructure costs of these upgrades are not unfairly shifted to everyday ratepayers . Accommodating co-location agreements, establishing clear procedures for data centers that bypass traditional grids to build directly next to power plants . Creating new transmission services for flexible loads that can throttle their operations or switch to onsite batteries to support grid reliability . Developing a transparent process to study how local grid stability is impacted when massive new loads are placed close to existing generation assets . In addition to the 60-day reform deadline, the grid operators have just 30 days to submit a detailed report outlining how they will ensure sufficient generation exists to serve both everyday users and these massive new data centers . Ultimately, the mandate is designed to force grid planners to look at best practices across the country and implement rigorous rules so that existing ratepayers do not get hurt by the rapid expansion of AI technologies Support the show 🎙️ About Energy Future: Powering Tomorrow’s Cleaner World Hosted by Peter Kelly-Detwiler , Energy Future explores the trends, technologies, and policies driving the global clean-energy transition — from the U.S. grid and renewable markets to advanced nuclear, fusion, and EV innovation. 💡 Stay Connected Subscribe wherever you listen — including Spotify , Apple Podcasts , Amazon Music , and YouTube . 🌎 Learn More Visit peterkellydetwiler.com for weekly market insights, in-depth articles, and energy analysis.
