Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

FactSet Power & Utilities client library for JavaScript

API Version npm Apache-2 license

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

  • Node.js >= 18

Installation

npm

npm install @factset/sdk-utils @factset/[email protected]

yarn

yarn add @factset/sdk-utils @factset/[email protected]

Usage

  1. Generate authentication credentials.
  2. Setup Node.js environment

    1. Install and activate Node.js >=18. If you're using nvm:

      nvm install 18
nvm use 18

    2. (optional) Install yarn.

  3. Install dependencies.
  4. Run the following:

[!IMPORTANT] The parameter variables defined below are just examples and may potentially contain non valid values. Please replace them with valid values.

Example Code

const { ApiClient, UnitsApi } = require('@factset/sdk-factsetpowerutilities');
const { ConfidentialClient } = require('@factset/sdk-utils');

const apiClient = ApiClient.instance;

// 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-typescript#authentication
// for more information on using the ConfidentialClient class
apiClient.factsetOauth2Client = new ConfidentialClient('/path/to/app-config.json');

// Basic authentication: FactSetApiKey
// See https://github.com/FactSet/enterprise-sdk#api-key
// for information how to create an API key
// const FactSetApiKey = apiClient.authentications['FactSetApiKey'];
// FactSetApiKey.username = 'USERNAME-SERIAL';
// FactSetApiKey.password = 'API-KEY';

const apiInstance = new UnitsApi();
const plantUnitsRequest = new factsetpowerutilities.PlantUnitsRequest(); // PlantUnitsRequest | 

// Call api endpoint
apiInstance.listPlantUnits(plantUnitsRequest).then(
  data => {

    console.log('API called successfully. Returned data:');
    console.log(data);
  },
  error => {
    console.error(error);
  },
);

Using a Proxy

To add a HTTP proxy for the API client, you can set the proxyUrl for the ApiClient instance:

const { ApiClient } = require('@factset/sdk-factsetpowerutilities');

const apiClient = ApiClient.instance;
apiClient.setProxyUrl('http://username:[email protected]:8080');
