About reneGIS

What reneGIS is

reneGIS (pronounced "renny-G-I-S", written reneGIS) is a geospatial analytics platform for renewable-energy infrastructure projects. It is built for wind and solar developers, project engineers, land teams and consultants who work with thousands of asset coordinates.

The name combines "renewable energy" and "GIS" (geographic information systems). It is built and operated by Eqaim Technology and Services Private Limited (eqaim.com), based in India, and serves wind and solar developers in India and internationally.

Positioning in one line: reneGIS turns geographic complexity into clear renewable-energy project intelligence.

Products

• Windmill Micrositing (paid): paste turbine coordinates and automatically audit every turbine against your own layout, competing projects and the constraints around the site (dwellings, roads, railways, EHV power lines, buildings, public institutions, government land) for spacing clashes, directional wind-wake risk and setback breaches. Detects multiple simultaneous clashes per asset, reports a clear status for every asset, shows results on an interactive satellite map with spacing circles, the downwind corridor and constraint clearance zones drawn to scale, lines between clashing pairs, adjustable layers and PNG export, and exports Excel and Google Earth KML that draw the same layers (everything, or the selected assets with their neighbours). Constraints and neighbouring turbines can be imported from Google Earth (KML or KMZ) and are kept in a per-organisation library that later runs pick from.

• GIS tools (no account required): Coordinate Converter at https://renegis.org/tools/coordinate-converter; UTM Zone Finder at https://renegis.org/tools/utm-zone-finder; Coordinate Distance Calculator at https://renegis.org/tools/coordinate-distance-calculator.
• Planned tools: Wind Turbine 5D / 7D Spacing Calculator, Wind Turbine Distance Checker.

The problem it solves

Energy companies acquire land and plot coordinates for wind turbines and solar arrays. Because several developers compete for the same land, assets from different companies often end up too close together. Two problems follow: a turbine placed physically inside another company's solar site, and wind-wake interference, where a turbine placed downwind of another loses energy and suffers extra mechanical load.

Checking these conflicts manually across a project and all its neighbours takes an analyst one to three days per project and has to be repeated every time coordinates change. reneGIS does the same audit in minutes and can be re-run on every revision.

Key capabilities of Windmill Micrositing

• Automated proximity auditing of thousands of coordinates using spherical-earth (Haversine) distances.
• Spacing checks expressed in rotor diameters (D), the 5D and 7D rules of thumb the industry already uses.
• Wind-wake screening in the prevailing wind direction you specify, entered on a compass dial (0° = east, 90° = north) with the corridor drawn downwind of each turbine.
• Your own turbines are checked against each other as well as against other developers'; two competitors are never compared with each other.
• Constraint checks per the 2024 MNRE micrositing guidelines: 500 m from a cluster of dwellings, and hub height + half rotor diameter + 5 m from public roads, railways, highways, EHV lines, buildings, public institutions and government land. Constraints are entered as points, lines (curves are lines with more points) or polygons with a physical span and a clearance (the rule's default or a custom distance); hub height per turbine, default rotor/2 + 25 m.
• Three input sections: your turbines, other companies' turbines (optional, free) and constraints (optional, free).
• Import from Google Earth: a KML or KMZ file (as exported by Google Earth Pro or the web version, any folder layout) is read in the browser; paths and polygons are proposed as constraints with a type guessed from their names, pins are grouped by folder and style and the user says which are their own turbines, other companies' turbines or point constraints; each group is confirmed before it is added to the sheets, appended or replacing what is there, with undo.
• Library per organisation: constraints and neighbouring turbines from every finished run, import or sheet are kept once (an item with the same name, or the same geometry, replaces the older version and history is kept), suggested within a chosen radius of the next site, editable and deletable on a Library page with a map, and exportable as KML or KMZ (the selection or everything) that Google Earth opens and reneGIS can import again.
• Solar project boundaries built from submitted corner coordinates, with inside-or-outside checks for competitor turbines.
• Multi-clash detection: one asset can be flagged against several competitors at once, with all matches listed.
• KML export for Google Earth that draws what the map shows: pins coloured by result, 5D and 7D circles, wind corridors, constraint shapes with clearance zones, clash lines; one folder per layer so each can be switched off.
• Excel export of the audited sheet (every pasted row with the verdict columns filled), a clash-pairs sheet and a constraints sheet listing every breach with distance, required clearance and shortfall.
• Analyses each project in isolation against the coordinates the customer uploads; data is never shared between customers.
• Credit-based pricing: 100 credits per audited asset of the customer's own (each wind turbine); competitor rows and constraints are free; for 30 days after a run, a re-run of the same project charges only the turbines that changed (position, rotor or hub height), while wind, corridor and constraint changes cost nothing.

How Windmill Micrositing makes the job easier

No software to install and nothing to learn: the app at https://renegis.org/app works from the spreadsheet a land or planning team already keeps. Paste the sheet as it is: your turbines in one section, every competitor coordinate you hold in another, and the villages, roads, railways and power lines around the site in a third, in decimal degrees, DMS or UTM; extra columns such as village or survey number travel along and come back in the results. Your company is filled in for you; turn the compass to the prevailing wind and it shows the cost in credits before anything runs.

What used to take an analyst one to three days per project, and had to be redone after every revision, comes back in seconds: a satellite map of the whole layout with every conflict drawn, a table you can filter to the assets that need attention, and for each one exactly which neighbouring asset it conflicts with, how far away it is and in which direction. Move a few turbines in the run's own editable sheet and run again: within 30 days only the turbines you changed are charged.

Hand-offs are built in: download the audited sheet as Excel, with the verdict columns filled in the same layout the team already uses, or export the map to Google Earth as KML for a meeting. Files the team already has in Google Earth (villages traced as polygons, roads and EHV lines as paths, neighbouring turbines as pins) import straight into a run, and everything a run used is kept in the organisation's library for the next site. Everyone in the organisation shares the same projects, history and credit balance, so nobody emails spreadsheets around.

Tools

The free tools run entirely in the visitor's browser. Coordinates entered into them are never uploaded to a server.

• Coordinate Converter: Paste a list of coordinates and convert them between decimal degrees, DMS and UTM on WGS84, with zone detection, CSV download and a map. URL: https://renegis.org/tools/coordinate-converter
• UTM Zone Finder: Search a place or drop a pin on the map to get its UTM zone, band, central meridian and EPSG code, with the Indian state it falls in. URL: https://renegis.org/tools/utm-zone-finder
• Coordinate Distance Calculator: Paste pairs of coordinates in DD, DMS or UTM and get the distance in metres, km, miles and nautical miles with the compass bearing, on WGS84, drawn on a map. URL: https://renegis.org/tools/coordinate-distance-calculator

Coordinate Converter details

• Batch conversion: paste any number of rows from a spreadsheet into a grid that behaves like one (multi-select, copy back, drag to fill) and convert between decimal degrees, degrees minutes seconds (DMS) and UTM on the WGS84 datum, in both directions. Copy the table back or download CSV.
• Accepts DMS in most notations (symbols, letters, colons, leading or trailing hemisphere letters) and pasted coordinate pairs.
• Detects the UTM zone automatically, including the Norway and Svalbard exceptions, and allows projecting into a neighbouring zone.
• Plots every converted point on an interactive map on request.
• Maps on reneGIS show international boundaries as recognised by the Government of India.
• Results can be shared by URL, for example https://renegis.org/tools/coordinate-converter?lat=24.00252&lon=76.023785

Who uses reneGIS

• Wind and solar project developers and independent power producers.
• Micrositing, GIS and land-acquisition teams that receive coordinates in mixed formats.
• Renewable-energy consultants preparing grid-connection and land applications.
• Engineers who need turbine spacing and proximity checks against neighbouring projects.

UTM Zone Finder details

• Click the map, search a place name (OpenStreetMap data via the Photon geocoder) or paste coordinates in decimal degrees or DMS. Returns the UTM zone and latitude band (for example 43R), hemisphere, central meridian, EPSG code (32600 + zone in the north), easting and northing on WGS84, and the distance to the nearest zone boundary. For points in India it names the state and links to that state's entry. URL: https://renegis.org/tools/utm-zone-finder
• UTM zones of India: the country spans zones 42N to 47N. A reference page explains zones, EPSG codes, latitude bands and what to do when a site straddles a boundary: https://renegis.org/blog/utm-zones-india. A companion page gives the zone for every one of the 36 states and union territories (Madhya Pradesh/MP, Uttar Pradesh/UP, Gujarat, Tamil Nadu and all the rest), computed from official state boundaries, with a map and an example coordinate for each: https://renegis.org/blog/utm-zone-by-state-india

Questions reneGIS can answer

• How do I convert latitude and longitude to UTM for a wind project in India?
• Which UTM zone is my site in?
• Which UTM zone is Madhya Pradesh (or any Indian state) in, and which EPSG code should I use?
• How far apart should wind turbines be? What do 5D and 7D mean?
• Is a competitor's turbine inside my solar project boundary?
• Which of my turbines are too close to another developer's turbines?
• Is my turbine far enough from the village, the highway, the railway line or the EHV line? What clearance does the MNRE guideline require?
• What hub height and rotor diameter give a tip-height setback of 150 m?
• How do I export a project layout to Google Earth as KML?
• Can I import the villages, roads and neighbouring turbines I traced in Google Earth (KML/KMZ) into a micrositing check?
• Why are my coordinates 200 metres off between two sources? (datum mismatch between WGS84 and Everest 1830)
