Launching in Italy and Greece.
ampear collects what grid operators, regulators and ministries publish about getting projects connected to the grid, and puts it in one place per region, with its history. For a single project, it turns that into a report with a fixed scope: what the queue and curtailment mean for it, and what a battery earns. Every figure links to its source.
A preview built from real published figures. Switch country and pick a region on the map or with the buttons. You see where the high-voltage grid runs, how much capacity is waiting to connect and how far it has got.
Pick a highlighted region on the map, or use the region buttons. Published figures per region: solar for the three regions with the most solar requests, data centres for the five regions with the most data centre requests. Grid: © OpenStreetMap contributors (ODbL). Boundaries: ISTAT (CC BY 4.0).
Most requested capacity is not ready to build, yet these requests still hold grid capacity, so new projects are told the grid is full ('virtual saturation'). The decree of 8 September 2026 aims to free that capacity. ampear will track the gap per region, every month.

Data centres have asked Terna for 101 GW of connections across Italy, almost half of it in Lombardy. Only 15 projects (1.88 GW) are ready to build: 14 in Lombardy and 1 in Piedmont.

GWh per year of wind output lost because Terna ordered wind farms to cut output to keep the high-voltage grid secure. Main causes in 2025: congestion 223 GWh, grid works 148, excess generation 188; ARERA gives no cause for the other 81. ARERA annual reports, from Terna data. Solar is counted separately and not included. Sources: 1 2 3

In Thessaly, twice as much capacity has been cancelled as is still waiting. 268.1 of the 379.2 MW cancelled was dropped after HEDNO told the projects the grid had no room for them.
In Western Macedonia, 89.7% of the cancelled capacity was dropped after HEDNO told the projects the grid had no room for them.
In Attica, 63.7 of the 86.1 MW cancelled was dropped after HEDNO told the projects the grid had no room for them.
Crete has 85 active energy communities. Since May 2025 a 1,000 MW cable from Attica has carried power to the island.

We run your project through the published data and the ampear simulation engine and deliver a report with a fixed scope: curtailment and prices, what a battery earns, and which rule changes move the answer. Every input and assumption is in the report.
A 1 MW solar park in Thessaly, or 20 MWp of solar plus storage in Puglia.
What do curtailment and low prices cost, and when does a battery pay back?
A business park on three local grid lines, or a municipality spread across several substations.
Which cables and transformers overload first, and where does flexibility help most?
Puglia in 2030 if half of today's connection queue gets built.
How much output could be lost when the region produces more than it can use or export?
Reports are indicative, for screening and early due diligence, and are not bankable studies. They complement, and do not replace, your independent advisor. There is no self-serve platform yet: we run the scenarios for you.
Two screening reports on illustrative projects, one per country, coming in October 2026. Every figure carries its source; assumptions and limits have their own section.
What curtailment and negative prices cost over the last 12 months, and battery options with and without a subsidy.
GR-01 · Greece · October 2026
The connection queue, curtailment by cause, battery economics, and what the new capacity caps change.

Two screening reports on illustrative projects, one for Greece and one for Italy.
The same report on your own park or project, with a published scope.
A public map with a page per region and grid area: how much capacity is waiting to connect, by technology and stage, and how much room is left, with the history. Every figure keeps its source and the date we retrieved it.
Follow regions and areas and get an email when a rule changes or an application window or auction opens. Query the atlas from your own tools and AI assistants.
