Why not convert all #elevators to operate with #gravitybatteries? #Cities could power their #grids with the savings.

They’re also a great storage companion to rooftop solar.

Starting January 2024, new residential heat pumps and EV charging points in Germany 🇩🇪 will need to be able to temporarily reduce ⚡ on a grid operator's signal. Consumers benefit from quicker connection times (instant approval) and reduced grid fees.

I'm looking forward to presenting how grid capacity transparency, price signals, and flexibility procurement are three tools in the toolbox to mitigate grid capacity constraints for heavy-duty vehicle electrification. This can benefit both grid and fleet operators.

I'm also excited about the other presentations on Dutch experience, the role of bi-directional charging in this segment, and the panel discussion.

Join us on 16 November 👇

The dreaded 'Dunkelflaute' has spread across Europe (and beyond) as a word, a Germanism, but not as a reality: periods of more than 24 hours in which wind & solar together generate less than 20% of their theoretical maximum did not occur at European level in the period analysed 2015-2021.

#Dunkelflaute #grids

Box 5
Dunkelflaute or 'dark doldrum' (a) indicates a meteorological condition when little or no energy can be generated using wind and solar power for a whole day or longer. Such events are difficult to predict but put large stress on a decarbonised energy system. Fortunately, they are mostly localised in specific regions and hardly ever occur on larger geographic scales. While Dunkelflaute periods can persist in individual countries, they have not happened at the European level in the analysed 2015-2021 period.
Notes: (a) Defined as periods when wind and solar generation present a capacity factor (electricity generation / theoretical maximum as per rated power) below 20% for at least 24 successive hours.

Last month, two 🇪🇺 EU agencies (ACER, the European Union Agency for the Cooperation of Energy Regulators, and EEA, the European Environment Agency) published this joint report looking at what countries should do to increase flexibility and resilience in the energy system: flexibility from all resources, large and small, and better interconnection for more cross-border flexibility.

Renewable energy developers are increasingly experiencing delays in getting connected to the grid (IEA report on grids just out - more on that later). The Danish grid operator Energinet has got tired of having to say "see you later, alligator" and has taken the second part of the phrase literally. New solar and wind projects can now be connected to the grid years earlier, by connecting to the overhead lines via "alligator plugs" in advance of a proper connection.

And the #OpenSimStatistics for September are in:

Metaworld Opensim Social wrote the following post Sun, 15 Oct 2023 18:31:28 +0200 OpenSim roundup

Land area records have been broken again, both for all #OpenSimulator #grids that have reported stats this time, for all those amongst them that are connected to the #Hypergrid and for some individual grids.

Not only is #OSgrid alone still bigger than #SecondLife, but it is so by almost 11%, even in comparison with Second Life's September 10th stats which I used the last time. For today, GridSurvey has reported that Second Life has slightly shrunk since September 10th. This does not change the fact that OSgrid has grown beyond 30,000 standard regions as well as beyond 2,000km².

The #WolfTerritoriesGrid is still hot on Second Life's heels at 94% of its land area. Now, while OSgrid is almost entirely hosted by the owners of the respective sims, all of #WolfTerritories was created and is owned by @Lone Wolf, and it runs on his servers. Granted, it helps that the grid mostly consists of large varsims which are made of multiple standard regions.

#Kitely is now larger than Second Life's Private Estates combined. Still, Kitely requires only a fraction of Second Life's server power because sims with nobody on them are automatically shut down and powered back up when someone wants to visit them.

As always, add #ZetaWorlds, and you've got three times Second Life's entire landmass. And the nine biggest #OpenSim grids, all on the Hypergrid, make up four times Second Life's landmass. Last month, this still required eleven grids. Down from there, grids quickly get smaller. The 13th-largest grid is already under 1,000 standard regions, and around the 40th place, grids have only 140 standard regions, so I'm not sure if five times Second Life's landmass can be amassed, especially if only grids on the Hypergrid count.

It's a pity that there are no stats on the actual number of sims. It'd be interesting to see their average size, and especially sailing grids would be way up this ranking.

TIL notes that the 🇸🇪 Stockholm region has three distribution system operators. It is good that they are working together in a single local flexibility market that is open, for example, to EV charging.
It's a winter-only market, with the next round running from 1 December 2023 to 31 March 2024. Applications before 1 Nov, minimum bid size (can be aggregated) 100 kW.

#Decentralized Energy Production Shakes Up Traditional #Grids

– Power grids must adapt to challenges such as increased electricity #demand, #variable energy sources, and a more decentralized model.
#VirtualPowerPlants, formed by prosumers, are emerging as a resilient solution for managing power production and storage.
– Significant financial investments are needed to upgrade energy infrastructure, with the US Dept of Energy already allocating $100 million for VPPs.

Here's a premiere: the first #FollowFriday for #OpenSimulator.

For those who don't know what I'm talking about: OpenSimulator, also called #OpenSim, is a free and #OpenSource platform for 3-D #VirtualWorlds that uses largely the same technology as #SecondLife. It was launched as early as 2007. It mostly became a network of #federated, interconnected worlds (#grids) when the #Hypergrid was introduced in 2008. And "#Metaverse" has been a part of the standard OpenSim vocabulary since before 2010, too.

It currently measures about 420 public grids at various sizes from tiny to slightly larger than Second Life itself and countless private grids, the vast majority of which are on the Hypergrid.

So without further ado, here are some suggestions:

Increasingly flexible energy production and consumption requires distribution system operators to look for new tools to manage their networks.
Market-based procurement of distributed flexibility facilitates a granular response to grid needs. The Portuguese🇵🇹 DSO E-REDES has now launched its first call for a flexibility auction in 8 regions, open to many: specifically including residential customers and charge point operators.

and therefore shows the urgent need for countries such as Germany to move forward with the planning of truck charging infrastructure


Countries in central Europe, such as Germany and Belgium, have many trucks passing through (about 50% of trucks on German
highways are just traversing the country) and are thus more important for inter-European long-haul transport. These countries have the highest utilization rate for their charging areas, with over 100 BETs stopping at their areas daily, demanding over 53 MWh on average. Large investments are required to allocate and install chargers and develop the power grid and electricity supply to meet demand from charging areas. Developing charging infrastructure in these countries as soon as possible is essential for BETs with long travel (i.e., long trip chains). Thus, there is an urgent need to start planning since the deployment of the charging infrastructure network will depend on other processes such as grid development, permitting, and land use.
The power supply and the grid are major limitations when planning for charging regions, which might impact our charging region allocations.

Et conclue par dire que la mise en ouvre avec Grids est plus concise et nécessite moins d'efforts.
