  1. https://euroweeklynews.com/2025/06/18/spains-blackout-cause-finally-revealed/ The report itself https://d1n1o4zeyfu21r.cloudfront.net/WEB_Incident_ 28A_SpanishPeninsularElectricalSystem_18june25.pdf From here https://www.ree.es/en/operation Interestingly: - "The incident was NOT caused by a lack of system inertia. Rather, it was triggered by a voltage issue and the cascading disconnection of renewable generation plants, as previously indicated. Higher inertia would have only resulted in a slightly slower frequency decline. However, due to the massive generation loss caused by voltage instability, the system would still have been unrecoverable." The TL;DR sequence of events is summarised in the report as follows: - (Note: The generation that must comply with P.O. 7.4 regulates, in a mandatory way, voltage dynamically and independently of the active power they are generating, thus it ensures stable voltages in the network. and RCW = Renewable, Cogeneration, and Waste) 1. Forced oscillation at 0.6 Hz, possibly originating in a photovoltaic power plant in the province of Badajoz,triggers system-altering protocolized actions. Shunt reactors are operated, lines are coupled due to oscillations, and schedules are modified. (N-1) 2. Natural oscillation at 0.2 Hz triggers further system-altering protocolized actions. Shunt reactors are operated, lines are coupled due to oscillations, and schedules are adjusted. (N-2). 3. Generation under P.O. 7.4 does not absorb the required reactive power. (N-3). 4. Variations in RCW generation during active power regulation affect voltage control and many of them don't fulfil their obligations. (N-4). 5. The conventional generation requested after the oscillations was not connected. 6. Generation loss in distribution: P < 1 MW and self-consumption of 435 MW before 12:32:57 (N-5). 7. Inappropriate tripping of a generation transformer in Granada (N-6). 8. Inappropriate tripping of solar thermal generation (Badajoz) and tripping of photovoltaic (Badajoz) withoutpoint-of-interconnection data from transmission network (N-7). 9. Inappropriate tripping of a photovoltaic power plant connected also in the province of Badajoz but in a different transmission substation (N-8). 10. Tripping of three wind farms (Segovia) without point-of-interconnection data from transmission network. 11. Tripping of one wind farm and a PV plant located at the province of Huelva, without point-of-interconnection data from transmission network. 12. Inappropriate tripping of photovoltaic power plant in Seville (N-9). 13. Inappropriate tripping a PV generation located in the province of Cáceres (N-10). 14. Tripping of PV generation connected to a 220 kV substation located in the province of Badajoz, withoutpoint-of-interconnection data from transmission network. 15. Tripping of one CCGT unit located at Valencia (N-11). 16. Load shedding of pumping units and loads due to underfrequency results in increased system voltage. 17. The HVDC link operating in constant power mode continues exporting 1,000 MW to France. 18. Tripping of Nuclear Power Plant. (N-12)
  2. Elkie Brooks in fine voice, should have been a single!!
  3. It might be worth a trip to the Ampur office in the relevant area. They usually have a bunch of free construction plans on file which have cost estimates. Pick something that looks like what you want, check the date on the drawings, adjust for inflation, and you're gold.
  4. Are there any other clues?? And, of course, what is the purpose of the inquiry?
  5. It certainly looks like a shophouse as was originally noted if it has a living area, so it would be 16, 17 or 18. That said it could also be a commercial building. This would be a commercial building (no living area) which could look like the intial photo.
  6. Yeah a No.16, 17, or 18 would be more accurate then 🙂 Missed those on my first scan through of the document. Makes the construction cost rather cheaper 🙂
  7. I reckon ^^^, No.23 => Commercial Building <23m Looks something like this from outside. Add another floor and you could be approaching No.24 territory.
  8. Why did I immediately think of this scene? Fetching my coat 🙂 Warning - grown up language!!
  9. And then die when you "discover" that the original sparks put the switch in the neutral line or that your light has a "borrowed neutral"! Kill all the power at the main switch.
  10. I believe not at this time, I'm going to give it a go probably next week, maybe try with pink ID which has a Thai ID compliant 13 digit number.
  11. I've had a few "Genuine Fake Lorex" over the years, always the automatic Submariner. if they keep going it's usually the plating that wears off. One memorable incident in Hong Kong. Pete a workmate and long time friend, wandered into the office sporting a Submariner. "That's a nice fake Pete" "It's a bloody real one"
  12. High last night (big tide) nothing to worry about right now.
  13. Mine was yesterday the 12th. One assumes they staggered dates to avoid being over-run with people trying to activate the face thingy.
  14. Sadly, Ackybang hasn't been seen since 2020, Resa since 2018 😞
  15. Some posts that contravene AseanNow Community Standards have been removed. I know it's hot, but let's keep US politics out of unrelated threads please.
  16. More like a "duck-ati" Fetching my coat ...
  17. A few posts not conforming to AseanNow Community Standards have been removed.
  18. Dam level update from Gemini. Here's the latest information as of June 12, 2025, or as close as possible: Current Situation (June 12, 2025): Overall Reservoir Storage: As of June 9, 2025 (the most recent comprehensive data available), national reservoir storage had reached 43,246 million cubic meters, accounting for 57% of total capacity. These reservoirs still have the capacity to receive an additional 33,245 million cubic meters (43% of their full capacity). This indicates a healthy overall water situation for the start of the rainy season. Major Dams (Chao Phraya River Basin - as of June 9, 2025): The four major dams in the Chao Phraya River Basin (Bhumibol, Sirikit, Kwae Noi Bamrung Dan, and Pasak Jolasid) currently store a combined 13,158 million cubic meters, which represents 53%1 of their total capacity. They can still accommodate 11,713 million cubic meters of water. Specific percentages for individual dams (as of early June/late May 2025 reports): Bhumibol Dam: Around 55-57% of normal capacity (28% usable storage as of latest Thaiwater.net). Sirikit Dam: Around 53-58% of normal capacity (23-28% usable storage as of latest Thaiwater.net). Pa Sak Jorasit Dam: Around 16% of normal capacity (16% usable storage as of latest Thaiwater.net). This dam consistently shows lower levels compared to the others. Wachiralongkorn Dam: Around 55% of normal capacity (21% usable storage as of latest Thaiwater.net). Srinagarind Dam: Reported at 72.94% capacity (April 2025 data). Bang Lang Dam: Reported at 82.28% capacity (April 2025 data). Rajjaprabha Dam: Reported at 62.52% capacity (April 2025 data). Chao Phraya River & Discharge Rates: Recent continuous rainfall across several regions has increased water inflows. The Royal Irrigation Department (RID) has been actively managing discharge rates. As of a recent report (early June 2025), the RID found it necessary to gradually increase the discharge through the Chao Phraya Dam at station C13 (Sapphaya district, Chai Nat province) from2 600 cubic meters per second to 700 cubic meters per second, effective from June 9, 2025. This was due to rising water flow from the North. River water levels in northern Thailand's major tributaries remain within normal ranges. For instance, the Ping River near Banphot Phisai District in Nakhon Sawan was about 4 meters below the riverbank, and the Nan River in Chum Saeng District was 6 meters below (as of June 9, 2025). The water flow at station C.2 in Mueang Nakhon Sawan District (where the Ping and Nan rivers converge to form the Chao Phraya) measured 710 cubic meters per second, still approximately 7 meters below the riverbank. Recent Warnings/Events: On May 28, 2025, residents in Ang Thong and Ayutthaya were warned of possible Chao Phraya River overflow due to increased discharge from the Chao Phraya barrage, which had increased its water discharge to 1,000 cubic meters per second. This raised downstream levels by 0.6 to 1.7 meters. The Thai Meteorological Department has issued warnings of continued heavy rain in the North due to a passing monsoon trough, raising the risk of flash floods and landslides. Comparison with Last Year (2024): Higher Overall Storage: A significant point is that the total water volume in large-scale and medium-scale reservoirs as of May 25, 2025, was 3,022 MCM higher than in 2024 for all reservoirs, and 2,918 MCM higher for large-scale reservoirs specifically. The Northern region's reservoir volume was also 2,525 MCM (or 23%) higher than in 2024. This indicates a generally better water reserve situation at the start of the rainy season this year. Chao Phraya Dam Discharge: Last year, around late September 2024, the Chao Phraya Dam increased its outflow from 1,500 to 2,000 cubic meters per second due to higher water from the North. This was a significantly higher discharge rate compared to the current 700 cubic meters per second. This suggests that while there is an increase in discharge this year, it's not at the same critical levels as late last rainy season. Drought Concerns: In early May 2025, the Lam Takhong Dam in Nakhon Ratchasima was reported at its lowest water level in 20 years (9% capacity), highlighting that some regions are still facing drought challenges despite improved overall national storage. Last year, in November 2024, farmers in Korat were warned against a second rice crop due to low dam levels, indicating ongoing regional water stress. In summary: As of June 12, 2025, Thailand's major reservoirs appear to be in a better water storage position than at the same time last year, thanks to recent rainfall. The Royal Irrigation Department is actively managing dam discharges, with current increases being implemented in response to northern runoffs, though these rates are generally lower than peak discharge events seen in late 2024. The emphasis is on balancing flood mitigation with ensuring sufficient water for the dry season. However, localized drought concerns persist in some areas, like Nakhon Ratchasima. For the very latest real-time data, it is always recommended to check the official websites of the Royal Irrigation Department (RID) or Thaiwater.net, as water conditions can change rapidly with weather patterns.
  19. "Yeah guv, I found a decent looking plastic box by the bins and took it home". "Nah, when I opened it to clean it, it was empty apart from a few spiders". "12M in cash? Who would leave that by the bins?".
  20. Due to Madam's love of all things green, especially trees, I'm fighting a losing battle with leaves in our 16' above ground pool 😞 After a bit of a blow the pool is full of flowers, leaves etc. etc. The standard PVC covers keep the leaves out, but they flll with rain water (which rapidly goes yukky) and stretch requiring to be bailed out before swimming. Also, if I'm away for work, I return to a lovely green pool with a zillion, now sunken, leaves that need hooking out. Is anyone supplying mesh leaf covers in Thailand? Something like the Pooltree system https://www.pooltreesystem.com/collections/pool-tree-ball-system/products/pooltree-system-only?variant=21740801392718 although prefererably rather lower cost of course
