Capabilities

Tools

7 tools
account_status
API credit balance
Credits remaining on the calling key, and how to top up without a human.
Read only Idempotent
Input schema 
{'type': 'object', 'properties': {}}
county_profile
County grid profile
Full grid intelligence for one US county: queued MW, connected capacity, project count, median wait, lead technology.
Read only Idempotent
Input schema 
{'type': 'object', 'required': ['state'], 'properties': {'state': {'type': 'string', 'description': 'Two-letter state code'}, 'county': {'type': 'string', 'description': "County name, e.g. 'Loudoun'"}}}
interconnection_deadlines
Interconnection deadline calendar
Cluster request windows, filing deadlines and compliance dates for US interconnection queues, with days remaining. Every date carries its source and how well it has been checked — a date marked unconfirmed came from a secondary source and has not been verified against the authority's own tariff. Do not present an unconfirmed date as a commitment.
Read only Idempotent
Input schema 
{'type': 'object', 'properties': {'rto': {'type': 'string', 'description': 'PJM, MISO, CAISO, SPP, NYISO, ISONE, ERCOT or FERC'}, 'upcoming_only': {'type': 'boolean', 'default': True}}}
load_ledger
Data-center power requests (The Load Ledger)
Large-load connection requests — requests to connect big new DEMAND to the US grid. 528 requests on file from BPA and NYISO only; 494 state no end use, so most cannot be attributed to data centers or any other industry. Does not yet include ERCOT, PJM, MISO, CAISO, SPP or ISO-NE. Filter by state or size.
Read only Idempotent
Input schema 
{'type': 'object', 'properties': {'limit': {'type': 'number', 'default': 25}, 'state': {'type': 'string'}, 'min_mw': {'type': 'number'}}}
map_data
Map data (GeoJSON)
GeoJSON FeatureCollection of grid activity for rendering a map: generation queue by county, data-center power requests, and AI campuses.
Read only Idempotent
Input schema 
{'type': 'object', 'properties': {'layer': {'enum': ['all', 'generation', 'load', 'datacenters'], 'type': 'string', 'default': 'all'}}}
policy_events
Grid policy & moratoria
Tracked policy events — data-center moratoria, large-load tariffs, FERC and state dockets — with direction (opening/closing) and citations.
Read only Idempotent
Input schema 
{'type': 'object', 'properties': {'direction': {'enum': ['opening', 'closing', 'neutral'], 'type': 'string'}}}
search_projects
Search grid interconnection projects
Search 39,173 US grid connection applications by region, status, fuel, state or size. Returns project rows with MW, county, wait time and outcome.
Read only Idempotent
Input schema 
{'type': 'object', 'properties': {'fuel': {'type': 'string', 'description': 'Solar, Wind, Battery, Gas, Nuclear, Hybrid…'}, 'limit': {'type': 'number', 'default': 25}, 'state': {'type': 'string', 'description': 'Two-letter state code'}, 'min_mw': {'type': 'number'}, 'region': {'type': 'string', 'description': 'ERCOT, PJM, MISO, CAISO, NYISO, ISONE, SPP, BPA or a utility name'}, 'status': {'enum': ['active', 'completed', 'withdrawn', 'suspended'], 'type': 'string'}}}
