Feb 4, 2026 Tired of BESS commissioning delays? Start the process earlier than you think Teams often treat the commissioning of battery energy storage systems (BESS) as a late-stage checkbox rather than a project-defining discipline. Projects can succeed or fail during commissioning. However, most commissioning failures stem from organizational, contractual, and procedural lapses rather than technical issues. While many engineers and project managers bring deep experience in solar and wind, you can’t apply the same approaches to energy storage. Energy storage systems are more complex — both technically and commercially — and require a higher degree of integration, training, and engineering discipline to commission a battery energy storage system successfully. A structured, phased commissioning plan brings every discipline together from the outset with clear tasks, ownership, dependencies in their sequential order, and minimizes surprises and delays. This approach not only safeguards project integrity and compliance but also establishes clear responsibilities, fosters ownership, collaboration, and accountability among project stakeholders. Ownership, transparency, and accountability are non-negotiable. Commissioning is not simply that final checkbox at the end of the project. Instead, effective commissioning begins at project initiation and continues as an ongoing process, overlapping with construction, through to acceptance testing. Risks from early decisions made in isolation are often overlooked. However, their impacts become evident later in the project — triggering delays and costly fixes precisely when the schedule can least absorb them. Commissioning problems often result from a lack of a cohesive, integrated plan that considers all stakeholders. While each contractor may have its own comprehensive Responsible, Accountable, Consulted, and Informed (RACI) matrix, minimizing commissioning risks requires a single, fully integrated RACI matrix that addresses all the project’s components and phases. Defining ownership, clear roles, responsibilities, accountabilities, and dependencies at the outset of the project ensures smooth handovers. EPCs, subcontractors, OEMs, owners, and other involved parties often identify scope gaps too late to avoid scheduling delays. These details, although small, are easily overlooked, yet can cause massive headaches and costs. A fully integrated commissioning may seem prohibitively long, detailed, and too complicated for practical use. However, the lack of a master plan often results in rework, confusion, back-and-forth, and ultimately, schedule delays and liquidated damages. Planning for the entire commissioning sequence from the beginning through to project final acceptance reduces surprises later in the project. A good rule of thumb is to plan for the worst and be pleasantly surprised at the end. From silos to signal: coordinating the whole commissioning team Facilitating communication across the entire team helps close gaps. While large calls with multiple parties may seem inefficient, so are commissioning delays! As painful as these calls may be, they remain a necessary investment of time to catch inconsistencies and miscommunication. Daily check-ins focused on commissioning and testing serve as essential touchpoints, breaking down silos, synchronizing activities, and clarifying accountability. At this stage, a third-party commissioning expert becomes invaluable. A seasoned facilitator knows which questions to ask, spots potential red flags long before they turn into schedule killers, and guides both live discussions and asynchronous communication to keep progress on track. Robust standards exist, but compliance doesn't always follow. A common misconception is that BESS is too new and lacks robust regulatory standards, especially for fire risk and safety compliance. In reality, the National Fire Protection Association (NFPA) and the National Electrical Code (NEC) have evolved in step with the industry, with meaningful updates such as UL9540A (5th edition), UL9540 (3rd edition), and new ESS-specific requirements in the upcoming 2026 NEC edition. Additionally, long-standing international standards, like IEC 62619 and the IEC 62933 Series, provide comprehensive safety and performance codes and standards that are well-established, vetted, and globally referenced for decades. The real issue with standards isn’t their existence — it lies in how seriously they are taken. It may be tempting to accelerate the design or testing process by selectively interpreting statutes and accepting the “minimum viable compliance” rather than delivering true industry best practices and high-quality adherence. This pressure often stems from the substantial financial incentives tied to the contractual completion milestones. When completion milestones trigger large contractor payments and give owners progress to report to investors, both sides feel the pull to “just get it done.” Under pressure, shortcuts can start to look appealing. Common shortcuts I’ve seen include incomplete test reports, missing serial numbers and calibration certificates, omitted verification steps, and insufficient photographic documentation. In the worst cases, critical equipment such as medium‑voltage transformers or battery modules — impacting system capacity — end up on the punch list. Once that happens, the finger-pointing begins, or worse, teams walk away assuming “someone else will deal with it.” Experienced contractors know the compliance standards. Shortcuts rarely result from ignorance — they come from gaps in structure, accountability, and oversight. A robust, well-designed commissioning plan is the strongest tool you have to minimize the opportunity for mistakes, both intentional and unintentional. Commissioning ultimately tests project leadership, and many projects stumble right at the final stages. Yours does not have to be one of them. Don’t let your project fall into these preventable pitfalls; develop a well-informed plan from the beginning. Lynn Appollis Laurent < Back Back

Feb 2, 2026 PJMInterconnectivity The Base Residual Auction The 27/28 Reliability Pricing Model (RPM) Base Residual Auction (BRA) cleared ~ 135 GW of Unforced Capacity (UCAP) at an RTO wide cap of $333.44 per MW-day Only ~ 809 MW of UCAP did not clear due to those resources being priced above the temporary price cap of $333.44 per MW-day Note, this price cap is expected to go away in the upcoming auction in June/July 2026 For those struggling to convert, this is equivalent to $10 per kW-mo In the absence of the cap, the auction would have effectively cleared at $529.80 per MW-day (Rest of RTO) with a reserve margin of 15.1%, clearing somewhere in the range of $26.3B The RPM cleared 14.8% of Installed Reserve Margin (IRM), 5.2% below the 20% IRM. For context, the IRM is the margin required to maintain a one-day-in-10 years Loss of Load Expectation (LOLE) According to estimates, PJM is short of 6.62 GW of UCAP The Bottom Line The price came in at the FERC-approved cap, $333.44/MW-day (UCAP) for the entire PJM footprint, a slight increase (+1.3%)from the 2026/2027 Base Residual Auction . The cap, agreed to be in place for the Base Residual Auctions for delivery years2026/2027 and 2027/2028, is calculated using the accredited capacity of the PJM reference resource. The cleared supply in the auction times the clearing price totals $16.4 billion, although not all load pays this clearing price because of the impact of self-supply and bilateral contract arrangements. Generation Resource Mix The cleared resource mix in this auction includes: 43% natural gas, 21% nuclear,20% coal, 5% demand response, 4%hydro, 2% wind, 2% oil and 1% solar The latest auction results were driven by a 5,250-MW increase in PJM’s demand forecast, almost entirely driven by datacenters, and a roughly 370-MW increase in cleared “unforced capacity” compared to the last auction Reliability risk has shifted from ‘fuel security’ to ‘capacity sufficiency’ Where prior reliability concerns focused on winter gas performance, this time around, the system is short of accredited capacity itself Even perfect performance wouldn’t fix a structural MW/MWh gap Effective Load Carrying Capability Even at record capacity prices, PJM is still not able to attract meaningful storage capacity as well as large-scale renewables This is telling because if high prices are not enough to incentivize investment, the issue is less to do with cost of revenue capture , but more to do with interconnection, accreditation, and rules-based risk Clues from the Queues Based on the interconnection queue, there is ~2,500 MW of offshore wind , 914 MW of solar, 732 MW of BESS, and 569 MW of natural gas under construction at the time of writing Withdrawals took center stage in the last 12-18 mos., where we saw ~37,442 MW of solar, 35,659 MW of BESS, 21,669 MW of natural gas, 7,414 MW of hybrids, 5,117 MW of offshore wind, 3,602 MW of onshore wind exit the queue due to a variety of reasons The greatest number of withdrawals took place in PA, VA, IL, and IN, respectively By capacity, VA and MD have the most projects currently under construction, whereas from a pipeline perspective, IL, VA, and OH have the most projects currently active in the queue This underscores the fact that ne generation response continues to remain weak in PJM. The BRA is signaling scarcity and it’s not going to get better without serious reforms The auction increases the probability of an ‘out of market’ action by PJM, indicating market design as a hurdle this weakening investor confidence in RPM Load Growth PJM has flagged that one of the major drivers of the tight supply-demand balance is the increase in forecasted load , to the tune of + 5,249.9 MW, mostly attributed to large loads Summer: Projected to average 3.1% per year over the next 10-year period and 2.0% over the next 20 years Annualized 10-year growth rates for individual zones range from 0.1% to 6.3%; median of 0.7% Winter: Projected to average 3.8% per year over the next 10-year period, and 2.4% over the next 20 years. Annualized 10-year growth rates for individual zones range from 0.1% to 6.0%; median of 1.6% Some Key Takeaways There was no price discovery this auction – it hit a wall When every LDA clears at the cap, price loses locational signaling value Demand Response was the quiet winner. Required Demand Response (DR) availability increased to all hours in the year, and the calculation of the winter peak load was updated to a coincident value. This was a major driver to an increase of the ELCC value for DR from 69% in the 2026/2027 BRA to 92% in the 2027/2028 BRA If the shortfall continues for two consecutive BRAs, PJM will trigger a Reliability Backstop Auction (RBA) with prior filing with FERC This is almost certain given the large gap between supply and demand The clearing solution may be required to commit capacity resources out-of-merit order but still in a least-cost manner to ensure that all these constraints are respected. In those cases where one or more of the constraints results in out-of-merit commitment in the auction solution, resource clearing prices will be reflective of the price of resources selected out-of-merit order to meet the necessary requirements PJM submitted $0 offers for specific Reliability Must-Run units and will allocate the revenue as a credit to the associated load The Chanceford-Doubs 500 kV backbone transmission line was delayed , which significantly impacted MAAC, SWMAAC and DOM CETLs.

Jan 14, 2025 New Acquisition Opportunity in ERCOT At Camelot, we always try to keep a finger on the pulse of the solar and energy storage M&A market, as many of our clients turn to us for technical and market due diligence on these sorts of engagements. We just had a noteworthy M&A opportunity come across our desk from our friends at Enerdatics and wanted to share this opportunity with our network. It’s for one hybrid (Solar + BESS) project in ERCOT – a region where many folks have had development and acquisition interests. A few details to highlight: Project located in Reeves County (West Hub) Point of Interconnect PV Capacity is 16.1 MWdc and BESS Capacity is 28.2 MWh (Assumed to be a 2-hour battery with an overbuild). It’s designed to participate in ERCOT as a Settlement-Only Distribution Generator (SODG) with Clip Charge and Energy Arbitrage. Solar PV will employ bifacial modules with single-axis tracker and the BESS equipment will use Li-ion technology. Interconnection is planned with Texas New Mexico Powe Company (TNMP), with a 12.47 kV voltage specification, connected to a substation, which is 0.3 miles from project to Point of interconnect. Key milestones such as the completion of Initial Assessment (IA) studies and Phase I ESA have been achieved for both sites. Due to its location, there are no county requirements for environmental permitting. Given the project size, state permitting requirements are also favorable. Lease agreements for 30+ years have been secured Approx. 70 Acres secured, possibly allowing future additional buildout Anticipated COD in Q4 2025. Camelot has recently performed diligence on, and supported the development of, several projects in ERCOT (“TX 10’s”) and we find that revenues can vary widely based on the specific node, though volatility in the region is moderate and favorable to BESS project economics. The DC-coupled configuration is somewhat unique to the market, allowing clipping capture from the solar side, but making market participation more difficult; In ERCOT, regardless of the coupling configuration, the solar and the BESS systems apply for interconnection separately. Camelot also has recent data on CAPEX and OPEX applicable to the region, and can perform a wholistic economic analysis of the projects to verify the seller’s assumptions. Overall, depending on the quality of the development of course, this could be good opportunities in an active market.

Feb 13, 2025 NERC’s New Compliance Threshold Big changes are coming for renewable energy projects in North America. Starting in May 2025, NERC will require all inverter-based resources (IBRs) with an aggregate nameplate capacity of 20 MVA or more—connected at 60 kV or higher—to register as a Generator Owner (GO) and/or Generator Operator (GOP). If your solar, wind, battery storage, or fuel cell project falls into this category, compliance is no longer optional—it’s mandatory. 1. Understanding the New Requirements Historically, NERC registration was only required for facilities above 75 MVA and 100 kV, but these new thresholds mean that many mid-sized energy projects will now be subject to NERC oversight for the first time. The goal? Enhancing grid reliability as more inverter-based resources connect to the bulk power system. 2. Key Steps for Compliance If your project meets the new criteria, here’s what you need to do: Assess Your Facilities – Determine if your current or planned projects exceed the 20 MVA and 60 kV thresholds. Begin the NERC Registration Process – Registering with NERC isn’t an overnight task. The process can take 6–12 months, depending on factors like documentation requirements, technical assessments, and coordination with regional reliability entities. Early registration helps avoid bottlenecks and ensures compliance well ahead of the May 2026 enforcement deadline. Develop a Compliance Plan – This includes: Meeting NERC Reliability Standards , such as PRC-024 (Generator Frequency and Voltage Protection) to ensure proper coordination with the grid. Updating operational procedures , like implementing real-time monitoring systems to log and report grid disturbances. Training personnel on cyber and physical security best practices to align with CIP (Critical Infrastructure Protection) requirements. Conducting regular audits to ensure ongoing compliance with evolving regulations. Engage with Experts – Compliance can be complex, and mistakes can be costly. Partnering with experienced professionals ensures a smoother transition. 3.
