The AMS-III.BB methodology is a pivotal framework under the Clean Development Mechanism (CDM). This methodology focuses on projects that supply electricity to communities previously disconnected from national or regional grids and reliant on high-carbon-intensive mini-grids or stand-alone power generators. Additionally, it addresses the displacement of fossil fuel-based lighting systems, contributing to the reduction of greenhouse gas (GHG) emissions. In this document, we will go over the components of AMS-III.BB, exploring how it enables low-carbon-intensive grid and mini-grid electricity to displace high-carbon-intensive sources.
AMS-III.BB is tailored for electrification endeavors that bring power to communities previously excluded from national or regional grids. These projects typically serve areas where high-carbon-intensive mini-grids or stand-alone generators were the primary sources of electricity. In some cases, fuel-based lighting systems were also in use before project implementation.
A fundamental goal of AMS-III.BB is the displacement of high-carbon-intensive electricity or lighting services with low-carbon-intensive grid or mini-grid electricity. By facilitating this shift, the methodology plays a significant role in mitigating GHG emissions and advancing sustainability.
AMS-III.BB projects have a broad reach, providing electricity to diverse consumer groups. These consumers include households, commercial facilities such as shops, public services, buildings, and small and medium-sized enterprises (SMMEs). The electricity generated can power a range of applications, from lighting to electrical appliances and even agricultural water pumps, thereby fostering economic development and improving quality of life.
A requirement of AMS-III.BB is that at least 75 percent of the project consumers must be households. This ensures that a substantial portion of the community benefits from the electrification efforts, aligning with the goal of inclusive development.
AMS-III.BB methodology is particularly relevant in situations where consumers were previously unconnected to national or regional grids. It also applies when a fraction of consumers previously reliant on carbon-intensive mini-grids transitions to a less carbon-intensive regional/national or mini-grid. In both cases, the methodology facilitates the transition toward cleaner and more sustainable energy sources.
While AMS-III.BB embraces various electrification approaches, it excludes portable electricity generating systems. This exclusion helps maintain the methodology's focus on more comprehensive and sustainable electrification solutions.

Effective metering and measurement are integral to AMS-III.BB projects. The methodology mandates metering of electricity consumption, particularly for Type I consumers expected to consume more than 1000 kWh per year. Prepaid devices for purchasing electricity are considered equivalent to traditional metering, ensuring accurate monitoring of energy consumption.
To facilitate accurate monitoring, some AMS-III.BB projects may require master-meters to measure the gross electricity sent out to all consumers. Additionally, sub-master-meters are utilized for those consumers who are not individually metered. Exceptions are made when all consumers are individually metered, or when a sample-based survey is employed.
For household consumers not individually metered (Type I-NM), consumption is calculated through various methods, including sub-master-meter readings or sample surveys. In contrast, metered households (Type I-M) and non-household consumers (Type II) have their consumption measured using standard electricity meters or billing records from prepaid connections.
AMS-III.BB methodology is limited to projects resulting in emission reductions of less than or equal to 60 kt CO2 equivalent annually. This cap ensures that the methodology remains aligned with its emissions reduction goals while allowing for flexible and sustainable electrification solutions.
AMS-III.BB is applicable under specific conditions, including:
Limited to communities lacking access to national or regional grids.
A requirement that at least 75% of the end users are households.
Key parameters play a vital role in the implementation and monitoring of AMS-III.BB projects:
During validation, the methodology necessitates the documentation of the physical location of each consumer, their anticipated connected load, and expected usage hours.
Monitoring involves metering the total electricity delivered to consumers, with the option of using prepaid devices for this purpose.
Metering is essential for tracking electricity consumption among non-household end users (e.g., commercial consumers, small and medium-sized enterprises, public institutions, street lighting, and irrigation pumps) and household end-users projected to consume more than 1000 kWh per year.
The AMS-III.BB methodology plays a vital role in addressing the growing need for sustainable electrification in communities that lack access to reliable electricity. It provides a structured approach for projects aimed at extending the grid or constructing new mini grids to connect consumers who were previously off the grid. These initiatives aim to displace high-carbon-intensive electricity sources and fuel-based lighting systems, thus reducing greenhouse gas emissions and fostering economic development in underserved regions. To understand the significance of AMS-III.BB, it's essential to compare the merits and considerations of mini grids versus grid electricity.
Mini-grids are localized power generation and distribution systems, often deployed in remote or rural areaswhere connecting to the national or regional grid is cost-prohibitive. They bring electricity to communities that were once reliant on high-carbon-intensive mini-grids or stand-alone power generators. While mini grids offer reliable electricity access and the potential to integrate renewable energy sources, they can be economically challenging to establish and may rely on fossil fuel generators. In contrast, grid electricity operates within large, interconnected networks, benefiting from economies of scale and efficient power transmission. Grids can access a diverse energy mix, including renewables, and are subject to stringent environmental regulations, generally resulting in lower emissions compared to mini grids. The choice between mini-grids and grid electricity depends on the specific needs, geographic location, and economic viability of the targeted community or region.

Project Proponent - The project proponent is responsible for executing the emission reduction project. The project proponent must adhere to the requirements outlined by the CDM and provide evidence of the emission reductions achieved. Upon successful verification, the project proponent receives certified emission reduction (CER) tokens as an incentive for their emission reductions.
Verification and Validation Body (VVB) - The VVB plays a critical role in independently verifying and validating the project data submitted by the project proponent. They thoroughly assess the project's emission reduction potential, methodologies, and adherence to the policy guidelines. Based on their evaluation, the VVB either approves or rejects the project for registration.
Registry (UNFCCC) - The United Nations Framework Convention on Climate Change (UNFCCC) serves as the registry for the CDM. They oversee the multiple workflow steps involved in the project's approval, including the verification and validation process by the VVB. The UNFCCC's approval is necessary for the project's successful registration and issuance of CER tokens.
