FactSet.SDK.FactSetPowerUtilities 0.1.0

FactSet Power & Utilities client library for .NET

The FactSet Power & Utilities API provides comprehensive global power generation and energy market data. Coverage includes power plant metadata and technical specifications, balancing authority supply and demand, power spot and forward prices, spark spreads, capacity prices, and hourly and monthly plant-level generation and emissions.

Note: Plant metadata and reference/mapping endpoints (Plants, ISO/TSO mapping, zone mapping) reflect current data only — historical or point-in-time values are not retained. The exception is GET /reference/entity-history, which provides historical entity and ownership records. Unit-level mapping information (unit names, EIA codes, project grades, and regional mappings) are included in the /units/details metadata response.

Key Features:

• Global power plant metadata including ownership, location, pipeline connections, and fuel-specific technical specifications (solar, wind, thermal)
• Balancing authority-level generation (by fuel type), demand, and net interchange data
• Power spot prices, spark spreads, capacity auction clearing prices, and forward power curves
• Hourly and monthly plant-level net generation with CO₂, N₂O, and SO₂ emissions data
• Reference data for ISO/TSO codes, price zones and hubs, and entity/ownership history

Units and abbreviations used throughout this API:

• MW — megawatt (unit of instantaneous power capacity)
• MWh — megawatt-hour (unit of energy; one MW delivered for one hour)
• $/MWh — US dollars per megawatt-hour (power price unit)
• $/MW-day — US dollars per megawatt per day (capacity market price unit)
• MMBtu — million British thermal units (heat input unit)
• Dth — dekatherm (one million BTU; unit for natural gas interconnection capacity)
• CO₂ — carbon dioxide; reported in metric tons
• SO₂ — sulfur dioxide; reported in metric tons (hourly) or short tons (monthly)
• N₂O — nitrous oxide; reported in metric tons (hourly) or short tons (monthly)
• BA — Balancing Authority; a grid operator responsible for balancing generation and load within its area
• ISO/TSO — Independent System Operator / Transmission System Operator
• EIA — US Energy Information Administration

Requirements

• .NET Standard >= 2.0

Installation

.NET CLI

dotnet add package FactSet.SDK.Utils
dotnet add package FactSet.SDK.FactSetPowerUtilities -v 0.1.0

NuGet

nuget install FactSet.SDK.Utils
nuget install FactSet.SDK.FactSetPowerUtilities -Version 0.1.0

Usage

1. Generate authentication credentials.
2. Setup .NET Standard 2.0 compatible environment.
3. Install dependencies.
4. Run the following:

Example Code

using System;
using System.Threading.Tasks;
using FactSet.SDK.Utils.Authentication;
using FactSet.SDK.FactSetPowerUtilities.Api;
using FactSet.SDK.FactSetPowerUtilities.Client;
using FactSet.SDK.FactSetPowerUtilities.Model;

namespace Example
{
    public static class ListPlantUnitsExample
    {
        public static async Task Main()
        {
            var config = new FactSet.SDK.FactSetPowerUtilities.Client.Configuration();

            // Examples for each supported authentication method are below,
            // choose one that satisfies your use case.

            /* (Preferred) OAuth 2.0: FactSetOAuth2 */
            // See https://github.com/FactSet/enterprise-sdk#oauth-20
            // for information on how to create the app-config.json file
            //
            // The confidential client instance should be reused in production environments.
            // See https://github.com/FactSet/enterprise-sdk-utils-dotnet#authentication
            // for more information on using the ConfidentialClient class
            ConfidentialClient confidentialClient = await ConfidentialClient.CreateAsync("/path/to/app-config.json");
            config.OAuth2Client = confidentialClient;

            /* Basic authentication: FactSetApiKey */
            // See https://github.com/FactSet/enterprise-sdk#api-key
            // for information how to create an API key
            // config.Username = "USERNAME-SERIAL";
            // config.Password = "API-KEY";

            var apiInstance = new UnitsApi(config);
            var plantUnitsRequest = new PlantUnitsRequest(); // PlantUnitsRequest | 

            try
            {
                // Returns power plant unit metadata and technical details
                PlantUnitsResponse result = apiInstance.ListPlantUnits(plantUnitsRequest);
                Console.WriteLine(result.ToJson());
            }
            catch (ApiException e)
            {
                Console.WriteLine("Exception when calling UnitsApi.ListPlantUnits: " + e.Message );
                Console.WriteLine("Status Code: "+ e.ErrorCode);
                Console.WriteLine(e.StackTrace);
            }
        }
    }
}

Using a Proxy

To use the API client with a HTTP proxy, setup a System.Net.WebProxy

Configuration c = new Configuration();
System.Net.WebProxy webProxy = new System.Net.WebProxy("http://myProxyUrl:80/");
webProxy.Credentials = System.Net.CredentialCache.DefaultCredentials;
c.Proxy = webProxy;
