Summary
Where matters: Integrating deliverability into voluntary clean energy market boundaries” is a white paper released by Singularity Energy with contributions from The Brattle Group and prepared for Google. The white paper introduces a new framework that can be used to help design more credible, impactful, and practical procurement boundaries for voluntary clean energy markets.

Voluntary procurement by corporate buyers has accounted for over 68 gigawatts of clean energy capacity added to the U.S. grid since 2014. These significant voluntary contributions to the clean energy transition have been guided and supported by procurement and carbon accounting standards such as the Greenhouse Gas (GHG) Protocol, RE100, and CDP.

However, there is a growing need for these standards to better align voluntary procurement with the physical and market realities of today’s electricity system. The framework presented in this paper is intended to help standards setters increase the credibility and consistency of clean energy claims and Scope 2 carbon accounting.

Executive Summary

Background

The voluntary clean energy market continues to play a growing and essential role in grid decarbonization. Voluntary procurement by corporate buyers has accounted for over 68 GW of clean energy capacity added to the U.S. grid since 2014, and voluntary purchases comprised about 6% of U.S. retail electricity sales in 2021, growing at a rate of about 20% year over year.

Standards and initiatives such as the Greenhouse Gas (GHG) Protocol, CDP, and RE100 all broadly incentivize voluntary procurement and influence the specific types of procurement decisions that are made. In addition to encouraging procurement from specific types of energy technologies, these standards and initiatives also importantly define the geographic boundaries within which a buyer can procure energy to comply with the standard.

The extent to which the location of procured electricity matches the location where a buyer consumes electricity has an impact both on the credibility of an individual buyer’s claim to be consuming the clean energy it procures, and on the aggregate impact of the voluntary market on the long-term success of the energy transition and full grid decarbonization.

Given the important role that standards play in shaping where voluntary buyers procure energy and the degree to which their procurement contributes to grid decarbonization, it is critical that standards setters define procurement boundaries using a process that is structured, transparent, and grounded in the reality of how electricity markets and electric power systems function. Today, boundaries are often poorly defined, unclear in their rationale, and not reflective of power markets and operations. They are often interpreted inconsistently, resulting in double-counting and the weakening of voluntary demand signals.

This is particularly true for the GHG Protocol’s Scope 2 Guidance on market-based accounting. This accounting approach, which allows companies to use market-based instruments to calculate their emissions from consumed electricity, lacks clear or robust guidance on the geographic boundaries within which clean energy can be purchased in order to match consumption and reduce market-based scope 2 inventories. Specific weaknesses of the current guidance include:

• The current guidance focuses on aligning with energy attribute certificate (EAC) markets, rather than electricity markets themselves.
