My reason for assuming that they would have made the same choices or in any case a broadly equivalent one is the fact that the BNetzA, the BMWE, and political stakeholders knew from the beginning of the renewable buildout that the combinati

I know how re-dispatch works. The issue is that the physical reality of the network and the location of generators and loads is fixed at time of [re-]dispatch. Regardless of how you reconfigure the dispatch mechanism, there is energy that c

Not all markets, and not even all European markets, assume a single trading zone (i.e. a copper plate network). Re-dispatch costs are high because policy choices have created a physical reality that drives high constraints. That could have

It's fine but a proposal to do something without the political will to make any of the difficult compromises required to achieve them is meaningless.

I mean, ok, fine guys but this is just more empty gestures from a club of empty heads in the GroenLinks/PvdA clown-car. I don't recall that they were against (in fact they were in favour) of the removal of the 30% tax rules intend

This is a terrible article, written by someone who is either dishonest or doesn't know what they're talking about and has never been to London, covering a paper that appears to be reasonably well done but has some serious limitati

>And while they are shutting down coal, they still have a huge former coal plant that is now burning biomass in London. That's a single plant that powers most of London. Do you mean Drax? That's nowhere near London. >And tho

Which damage? The electricity system has done most of its decarbonising under either the coalition or Conservative governments, they used quite a lot of the machinery (the CfDs, capacity market, etc) setup at the end of the last Labour gove

The timelines for encyclopaedia article contributions, editing and publishing are such that I highly doubt that an encyclopaedia bought in 2024 has much if any LLM generated content. I wouldn't want to make that bet for an encyclopaedi

Part of the problem is that heat pumps aren't really well suited to a use case where you frequently have to bring a house up to temp in the way you're describing. If you have a big overnight set-back and then the heating comes on

London as well, or at least broke even. (Although of course this is complicated to assess and contested). Same reason, all infrastructure was either already there or usable after (the Olympic stadium was sold to a football team). Generally

I think this is a dumb idea, but come on, all prosecutions are retroactive.

There's a policy decision to cover as much as possible of the operating costs of the network from fares rather than government funding. The operating costs of UK trains per passenger-km is actually pretty competitive to European compar

The heavy forged sections of a pressure vessel are really thick and there is a limit to how thick a single weld can be using conventional techniques. So you have to do many passes. Each one of those requires bringing the temperature of the

The tides are not constant but they are predictable. The majority of tidal flow is during relative short periods of only a few hours. In order to harvest tidal energy, truly enormous volumes of reinforced marine concrete have to be deployed

There's a huge amount of North-South capacity being built as part of the holistic network design programme which will unlock a lot of capacity and substantially reduce curtailment.

We (an engineering consultancy, so not software but physical infrastructure) have an internal ChatGPT so that people can use it for work. I find that it is quite good at answering textbook type questions and giving background on things. Bas

Plea bargains are heavily restricted in the UK and many of these cases were heard in Crown courts. I agree about getting rid of private prosecutions though.

There's broadly two reasons for this: One, the evidence for it being a carcinogen remains relatively weak compared to many other substances we know of. It's in that category of chemicals where possible effects show up at the lim

The Polish wholesale power price is above even what nuclear power costs to deliver in higher-cost UK and US markets on an LCOE basis (not that LCOE is a great way of comparing power costs but there it is).

PGE will finance it on-balance sheet, the way they would a coal plant. Most likely there will be US export finance for the elements coming from the US but most spend on big nuclear plants is local. >The recent nuclear plants constructed

In many places (but not the US because of thermostat standards) HVAC systems are now typically inverter driven as well so that does remove some of the advantages of three-phase since any individual load is single-phase anyway.

by Mvandenbergh 3y ago
The US also uses a different primary network configuration, typically running a three-phase network as main primary with single phase primary laterals. The pole-mount single-phase transformers then turn this single-phase into split-phase LV

The latest quantitative risk assessment of hydrogen in a domestic context is that slightly greater explosion risk is outweighed by the slightly lower fire risk. Hydrogen has a wider explosion range... but most natural gas explosions are fro

To be fair, while all of those things are true (and in fact the poor state of many rivers is more due to farming and to fully consented but still high-nitrate effluents from waste water treatment than to CSOs) the industry has really not ev

Nobody will build a heat-pump system with an on/off control system like that because the performance will be awful. Certainly not an air-to-water system.
