Tracked indicators
| Indicator | Value | Reading | State | Source |
|---|---|---|---|---|
| Energy | ||||
| Local grid carbon intensity How much CO₂ is emitted to produce the electricity the site will consume, based on the regional grid. The lower the value, the better. | 17.7 gCO2e/kWh | Measured | RTE eCO2mix (données définitives) — France national CO2 intensity, 12-month mean 2025-09-29..2026-06-30 (17.7 gCO2/kWh, n=13196 half-hourly) — accessed 2026-09-29 | |
| Grid connection capacity / proximity How easily the site can be connected to the power grid: available capacity and distance to the nearest substation. | grid saturated at the connection point | Measured | Caparéseau (RTE S3REnR) — poste RANTIGNY at 2.3 km: 1.0 MW available hosting capacity (updated 29/04/2026) — accessed 2026-09-29 | |
| Grid congestion / connection queue How congested the local grid is: the more saturated, the more the connection competes with other users. | moderate local grid congestion | Measured | Caparéseau (RTE S3REnR) — poste RANTIGNY at 2.3 km: 52.0% reserved-capacity fill rate (updated 29/04/2026) — accessed 2026-09-29 | |
| PUE (announced energy efficiency) The announced energy efficiency: total electricity used versus what actually powers computing. Closer to 1 is better. The lower the value, the better. | — | — | Not looked for yet We have not looked for this yet. It is dropped from the calculation and does not penalise the site. | — |
| Heat-network connectability Whether the site can valorise its waste heat via a district-heating network: distance to the nearest network and presence of a connection obligation (priority development perimeter). | no heat network nearby | Measured | France Chaleur Urbaine (data.gouv, lov2) — réseau de chaleur le plus proche : 60654 m (point→segment, Lambert 93) ; dans un PDP : non ; réseau classé : oui → eloigne (>1000 m) — accessed 2026-09-30 | |
| Waste-heat recovery — commitment Operator commitment level to valorise the site's waste heat (delivered / signed contract / study / intention / none). | heat recovery under study | Announced | Dossier d'enquête publique (SCI Alyssa, Rantigny) — 40 MW de chaleur fatale valorisable IDENTIFIÉE (réseaux de chaleur, serres ~20 000 m²) ; potentiel d'étude, aucun engagement contractuel signé → engagement niveau ÉTUDE — accessed 2026-09-29 | |
| Water | ||||
| Local water stress Water tension in the area: in an already water-scarce region, withdrawals weigh more heavily. | high water stress | Measured | VigiEau — drought-restriction status at point (accessed 2026-09-29) — accessed 2026-09-29 | |
| Water body status The ecological health of the affected river or aquifer, per the EU classification (from 'high' to 'bad'). | water body in moderate status | Measured | EEA WISE (WFD 2022) — water body FRHR220 'la Brèche du confluent de l'Arré (exclu) au confluent de l'Oise (exclu)': ecological status class 3/5 — accessed 2026-09-29 | |
| Basin withdrawal pressure How intensively water is already withdrawn from the basin: a heavily-tapped basin ill affords a new user. | low abstraction in the basin | Measured | Hub'Eau BNPE — commune 60524: 0.022 Mm3 withdrawn in 2023 (all uses, provisional pressure band) — accessed 2026-09-29 | |
| Cooling technology + announced water volume The cooling technology chosen and the water volume it will consume, as announced by the operator. | — | — | Not looked for yet We have not looked for this yet. It is dropped from the calculation and does not penalise the site. | — |
| Land & biodiversity | ||||
| Overlap / distance to protected areas How close the project is to protected natural areas (Natura 2000, nature reserves…). | protected natural area 1–5 km away | Measured | INPN / IGN API Carto — Natura 2000 & ZNIEFF overlap by distance ring — accessed 2026-09-29 | |
| Soil status (artificialized / natural / agricultural) What the land was before: already built (brownfield), natural, or farmland — sealing farmland or nature weighs most. | previously developed land | Measured | IGN API Carto GPU — PLU zoning 'UIa' — accessed 2026-09-29 | |
| Ecological corridors (TVB) Whether the project severs a wildlife corridor (green-and-blue network). | Not disclosed | — | Absent from the file We read the public file and the information is not in it. It counts as a zero in the grade. | — |
| Site ground footprint The SITE's ground footprint in hectares — the land the project takes up (buildings, roads, parking, substation, retention basins), not the building print alone: the larger, the greater the land impact. The lower the value, the better. | — | — | Not looked for yet We have not looked for this yet. It is dropped from the calculation and does not penalise the site. | — |
| Avoid-reduce-offset (ERC) measures Measures to avoid, reduce or offset harm to soil artificialisation and biodiversity. (Heat recovery moved to E6/E7, Energy pillar.) | Not disclosed | — | Absent from the file We read the public file and the information is not in it. It counts as a zero in the grade. | missing — la récupération de chaleur est passée en E7 ; le dossier ne documente pas de séquence ERC (éviter-réduire-compenser) exploitable telle quelle — accessed 2026-09-29 |
| Designated for urbanisation in a supra-municipal plan not scored · contextual fact Is the site designated for urbanisation in a planning document above the municipality? A contextual fact, published as such: it neither improves nor worsens the grade. | — | — | Not looked for yet We have not looked for this yet. It is dropped from the calculation and does not penalise the site. | — |
| Planning-document compatibility procedure under way not scored · contextual fact Is a procedure under way to make the planning document compatible with the project? A contextual fact: we follow the instrument, not the intention — the land status only changes the day the procedure completes. | — | — | Not looked for yet We have not looked for this yet. It is dropped from the calculation and does not penalise the site. | — |
| Local impact | ||||
| Municipality socio-economic profile The host town's social profile.

| Absorption capacity (project size vs municipality) The project's size relative to the town: a very large project in a small town disrupts more. The lower the value, the better. | 118.9 MW per 1000 inhabitants | Announced | puissance 300 MW (dossier ICPE SCI Alyssa, Rantigny, announced) / commune 60524 Rantigny 2 524 hab. (INSEE via geo.api.gouv.fr) = 118.9 MW pour 1000 hab, calcul déterministe — accessed 2026-09-29 | |

| Announced jobs The number of permanent jobs announced, relative to project size. More is better. The higher the value, the better. | — | — | Not looked for yet We have not looked for this yet. It is dropped from the calculation and does not penalise the site. | — |
| Announced tax revenue The tax revenue the project would bring to the town, as announced. | — | — | Not looked for yet We have not looked for this yet. It is dropped from the calculation and does not penalise the site. | — |
| Observed level of opposition The scale of observed opposition: appeals, petitions, mobilizations reported by the press. | Not disclosed | — | Absent from the file We read the public file and the information is not in it. It counts as a zero in the grade. | — |
| Elected officials' position (voted facts only) Elected officials' position as expressed by official votes only (council decisions), with no personal judgment. | Not disclosed | — | Absent from the file We read the public file and the information is not in it.

| Consultation / consent / governance (procedural proxies) The quality of the democratic process: public inquiry held, environmental authority opinion, appeals, CNDP referral. | — | — | Not looked for yet We have not looked for this yet. It is dropped from the calculation and does not penalise the site. | — |
| Documentation transparency / file availability How genuinely accessible the project's file is to the public: published studies, figures and commitments. | — | — | Not looked for yet We have not looked for this yet. It is dropped from the calculation and does not penalise the site. | — |
