The grid has been straining under the weight of new AI data centers, and that has utilities courting fusion startups.

I recently built a complete IT ticket management system in Power Apps — 9 screens, role-based access, live SLA tracking, and automatic email notifications. The part I want to actually talk about here isn't the UI, it's the SLA engine, because I built it to work without Power Automate , and the trick is simpler than it looks. The problem SLA tracking normally means: a ticket is "Critical" → 60 minute target → somebody needs to know if it's about to breach or already has. The obvious way to do this is a scheduled Power Automate flow that checks every ticket on a timer and flags the ones in trouble. I wanted this app to run on Power Apps collections only — no flow, no external data source — so a scheduled flow wasn't an option. The question was: can you get "live" SLA status without a background job? The trick: recalculate on every read, not on a timer Instead of a flow updating a SLAStatus field periodically, I recalculate it every time the app or a screen is opened, using Now() against the stored due date: \ UpdateIf( colTickets, Status <> "Resolved" && Status <> "Closed", { SLAStatus: If( Now() > DueDate, "Breached", DateDiff(Now(), DueDate, TimeUnit.Minutes) <= SLAMinutes * 0.2, "At Risk", "On Track" ) } ); UpdateIf(colTickets, Status = "Resolved" || Status = "Closed", {SLAStatus: "Met"}) \ \ This runs in App.OnStart , at the top of every screen's OnVisible , and behind a manual "Refresh SLA" button. The At Risk threshold is 20% of the SLA window remaining — so a Critical ticket (60 min target) goes At Risk with 12 minutes left; a Low ticket (1440 min / 24 hrs) goes At Risk with 4.8 hours left. The honest tradeoff: this only updates when someone has the app open. A ticket breaching at 2am with nobody looking won't trigger anything until the next visit. For a real production deployment I'd pair this with a scheduled flow for after-hours detection — but for a demo, an internal tool with regular traffic, or anything where "eventually consistent within the next visit"

Dealing with multiple Excel or CSV files is a common task in business. Whether it is sales reports from different regions, customer data across various campaigns, or financial records by month, the need to combine these files into a single, cohesive dataset is constant. Manually copying and pasting or even using complex formulas can quickly become a time sink, prone to errors, and a source of frustration. What if you could automate this repetitive process? Imagine setting up a workflow that automatically merges your Excel files for you. That is where Microsoft Power Automate comes in. And when your data is messy, inconsistent, or riddled with duplicates, AI tools can take your automation to the next level. This guide will walk you through building robust workflows in Power Automate to combine your Excel workbooks. We will also explore how AI can address the often overlooked challenge of data cleaning and standardization, turning disparate data into a clean, unified source. Why Automate Excel Merges? The benefits of automating Excel data consolidation extend beyond simply saving time. Consider these advantages: Time Savings: Free up hours spent on manual data handling, allowing you to focus on analysis and strategic tasks. Reduced Errors: Eliminate human error from copy-pasting, formula mistakes, or missing data. Consistency: Ensure data is merged and formatted uniformly every time, regardless of who runs the process. Scalability: Easily handle increasing volumes of files without proportional increases in manual effort. Timeliness: Get up-to-date consolidated reports faster, enabling quicker decision-making. The Old Way: Manual Merges and VBA Limitations For years, consolidating data meant either painstaking manual copy-pasting, using VLOOKUP or INDEX/MATCH across sheets, or resorting to VBA (Visual Basic for Applications) scripts. Manual methods are slow and error-prone, especially with large datasets or many files. VBA offered a significant improvement, providing c

The UK’s energy regulator is using a variety of tricks to keep speculative data center projects from plugging into the power grid. The country’s AI ambitions hang in the balance.

Fusion startup Pacific Fusion broke ground on a demonstration facility in New Mexico that it says will generate enough energy to power itself.

Capacity will rise by a record 45GW this year, according to S&P Global Energy.

Tesla's solar roof was an experiment that never really caught on for the company. But does that mean the concept of roof-integrated solar is dead?

Fusion power startup Inertia Enterprises reduced the fuel filling process from a week to just a few hours. It's one of ten hurdles the company must overcome to make a profitable power plant.

Y Combinator alumnus Apollo Atomics is shrinking a key nuclear reactor part, which promises to slash the cost of electricity below natural gas.

TerraPower's nuclear power plant possesses a strategic advantage over competitors, especially when chasing after data center deals.

Companies including Tesla and Base Power are vying for a piece of the rapidly growing market for home batteries. One technology has made it all possible.

This isn't a syntax error or a bug in the query — it's Power Query's Formula Firewall refusing to combine data from more than one source until it knows whether that's actually safe. Combining a private/organizational source with a public one (an internal database and a public web API, for example) can leak data from one into the other; the firewall blocks it by default rather than guessing. Why This Exists Every data source in Power Query has a privacy level — Public, Organizational, or Private — set the first time it's connected to. When a query's steps end up needing to send data from one source into a call against a different source, Power Query checks whether the privacy levels involved allow that combination.

Fusion startups have raised $7.1 billion to date, with the majority of it going to a handful of companies.

Utility-scale solar leads by a mile, followed by batteries. Fossil fuels, not so much.

A massive new gas plant in Texas will be built with much less efficient technology than regular gas plants. It’s far from the only data center power project to rely on dirty turbines.

Tesla wants to build a massive solar factory in Texas, but first it wants the state to chip in to defray the costs.

Fusion power startups are turning to Kyoto Fusioneering to supply components for future power pants. The Japan-based startup just received a grant to build a part of the fuel system.

One thing Microsoft is not good at is naming things, and sadly it's happened again. But let's go back to the beginning: what are Skills? Skills are targeted prompts/context that are modular, so they are not always included in the LLM session. They are Markdown files with selected metadata in YAML, all in a file normally named skill.md (the parent folder and YAML metadata identify it). They were created by Anthropic (Claude) and were designed for both the user to add in a prompt ( /Skill ), or for the LLM to decide. Similar to Skills are Plug-ins. These can (and often do) include skill.md files, but can also have scripts, MCP servers, and other tools. So back to Microsoft naming things badly. Copilot Studio (Azure Bot Framework version) had skills, but they were not skills. The new Copilot Studio has Skills, but they are not Skills, they are actually Plug-ins. Plug-ins include Skills, so why does it matter? Well, it doesn't really, but I like to moan, and it means sometimes cool functionality can be left on the table because we presume Microsoft names things accurately. Anyway I digress (I like to do that), now we understand what Skills/Plug-ins are I wanted to dive into them within Copilot Studio and cover: Why Are They Cool Building Powerful Skills Adding Scripts/Templates Using Skills 1. Why Are They Cool I often go on about skills being cool, but why? There are a few reasons. Context Management Before skills, the standard approach was to give the LLM everything and let it figure out what it needed. The problem with this is twofold. First, more context equals more tokens, which equals more cost. Second—and more importantly—too much unrelated context can have a detrimental impact on the LLM response. LLMs work by using input tokens to predict the next token, so polluted input tokens can make the LLM predict the wrong next token (this is a huge simplification, but you get what I mean). Transferable As skills are simple Markdown files, they can easily be transferred
