"Anticipation is growing around the release of version 4 of the NERC CIP-014 standard, which is expected to broaden the criteria under which locations fall within the CIP-014 eligibility scope. This standard, designed to enhance the security of transmission station locations in the bulk electric system and bulk power system, aims to prevent catastrophic cascading outages from the failure of single or multiple components. Here's what you need to know about the anticipated changes and how they might impact operations."

🔔Join our webinar: Countdown to Market-Wide Half-Hourly Settlement 🔔 📅 Date: 18th July, 2024 We are inviting all REC Parties to a Market-Wide Half-Hourly Settlement (MHHS) webinar on July 18th, 2024. In this webinar, we will explain the important changes MHHS will bring to REC arrangements, as well as the activities REC Parties must complete over the next nine months to ensure REC compliance. Key topics: ➡Changes to REC-owned data flows ➡Impact on CSS Switching arrangements ➡REC Change Proposal R0083 (changes to the supply number format) ➡Introduction of a table detailing metering configuration domain data ➡Support for forward/reverse migration ➡REC Performance Assurance and MHHS ➡Changes to the Electricity Enquiry Service Register now: https://lnkd.in/e_-YZEpX Find out more: https://lnkd.in/eCNrQPCg

As is currently practiced, the four Nordic TSOs, including Energinet, procure a fixed 600 MW of FCR-N (Frequency Containment Reserve for Normal Conditions) capacity for every hour, totaling 5,256 MW of capacity annually. FCR-N is activated when the frequency deviates between 49.9 and 50.1 Hz. In our recent work (https://lnkd.in/dfizykDi), we challenge this "static" reserve dimensioning approach and explore the potential benefits of a "dynamic" approach, where Nordic TSOs procure time-variant capacity on still an hourly basis. By developing a diffusion process to model frequency dynamics, calibrated with 300 million frequency data points from the Nordic grid, we found that dynamic dimensioning—while still procuring the same 5,256 MW of capacity annually—could reduce the probability of frequency deviation outside the 49.9-50.1 Hz range by 37%, while maintaining the target safety level of 98% (i.e., exceeding ±100 mHz for a maximum of 10,000 minutes per year). Disclaimer: This analysis assumes perfect forecasting of the frequency's standard deviation before the activation of FCR-N. Question: Is it the right time for Nordic TSOs to move toward dynamic dimensioning? As a conservative first step, a dynamic approach could be implemented while maintaining a minimum procurement floor of 600 MW. Jöbke Janssen, Alessandro Zocca, Bert Zwart

What share of converter based generation out of total generation could a "smaller" DSO expect? Asked and answered we turn to PowerBI and modify some of the graph for our own distribution system. The question was indirectly raised by Antti Harjula at Fingrid Oyj via a post here on LinkedIn (see comments) where the show that they have a 60%-ish penetration of converter based production. Well, given that we're a smaller system than the Finnish system my guess was that we would have both higher and lower shares which was confirmed by our data. We're reaching level's of up to 80% converter based penetration as of total production level and up to 200% as of share of total load. Given that we're connected to Svenska kraftnät it would be interesting to see a graph estimating the short circuit levels in their system at our connection points during times of high penetration levels. It'd also be interesting to estimate the levels of short circuit contribution by the converter based generation.

Reliability in the West: Inverter-based Resources—Registration Wednesday, April 3, 2024 11:00–12:00 p.m. Mountain Time The increasing integration of IBRs has led to a reliability gap where many IBR owners and operators connected to the Bulk Power System are not registered with NERC or complying with its Reliability Standards. In response, FERC issued an order in 2022 directing NERC to identify and register these unidentified IBRs. In March 2024, NERC filed proposed revisions with FERC that would lower the registration threshold for these resources. This discussion will highlight and review the effects of the proposed threshold changes. https://lnkd.in/gFPcWbeg

The Jury is back... 🐻 📉 Last week I asserted we were at an inflection point in relation to the upward trend for W24 #gas. We needed either a break above the previous high in order for the trend to continue, or for a break lower to signal a change. We have seen the latter, and both the medium term upward trendline and the short term support (S1) broken. The implication is that further losses are likely, a narrative which the broader supply/demand fundamentals would support. The next substantive support level (S2) is around 87ppt, though I suspect the whole number of 90ppt will also lend support in what is a tentative move at this stage. Decision making in this market is tough, as volatility and uncertainty have become the norm. If you aren't getting the support, analysis or firm recommendations based on your businesses position/strategy, then reach out to us at L&C Utility and we can support.
