`GET /emission-rates`

Get emission rate intervals for a given utility. Currently only supported for PG&E (id=1), SCE (id=2), SDG&E (id=57), LADWP (id=50). View list of supported utilities and their utility_id's [here](https://docs.pelm.com/reference/utilities).

## Query parameters

- `utility_id` integer, required
- `start_time` integer
- `end_time` integer

## Headers

- `Pelm-Client-Id` string, required
- `Pelm-Secret` string, required

## Response `200`

Successful operation

- object
  - `utility_id` integer — Id of utility
  - `ghg_emission_rate_unit` string — Unit for greenhouse gas emission rate (e.g. kg_co2e_per_kwh, which corresponds to kg of CO2 equivalent emitted per kWh of electricity consumed).
  - `intervals` object[]
    - `start` integer — The start time of interval in UNIX time
    - `end` integer — The end time of interval in UNIX time
    - `ghg_emission_rate` number — The rate of greenhouse gas emissions for this utility at a particular point of time. Calculated using historical demand and emissions data.
