== Introduction ==

Access to modern energy is widely recognised as a prerequisite for social and economic development. Reliable electricity and clean cooking services improve education, healthcare, livelihoods, food security and economic productivity while supporting progress towards multiple Sustainable Development Goals (SDGs).

Historically, progress towards universal energy access was measured primarily by counting the number of households connected to electricity. Although this indicator remains useful, experience has shown that an electricity connection alone does not necessarily provide meaningful access to modern energy services.

Many households with electricity experience frequent outages, poor voltage quality, limited hours of supply or tariffs that make electricity unaffordable for productive use. Similarly, access to clean cooking depends not only on the availability of improved technologies but also on factors such as affordability, convenience, safety, efficiency and exposure to harmful household air pollution.

Recognising these limitations, the World Bank's Energy Sector Management Assistance Program (ESMAP), in collaboration with international partners, developed the '''Multi-Tier Framework (MTF)''' as a comprehensive methodology for measuring energy access.

Rather than classifying households as simply "connected" or "unconnected", the framework evaluates multiple dimensions of electricity and clean cooking services to determine the extent to which energy improves people's lives.

Today, the Multi-Tier Framework is widely recognised as one of the world's most comprehensive approaches for assessing energy access and has been applied across numerous countries to support national energy planning, policy development and global monitoring of Sustainable Development Goal 7 (SDG 7).

== Why Measuring Energy Access Matters ==

Reliable information is fundamental to effective energy planning. Governments, utilities and development partners require evidence not only on whether households have access to electricity, but also on whether that electricity is sufficient to improve living standards and support economic development.

Traditional indicators often fail to capture important aspects of energy service delivery. For example, two households may both have electricity connections, yet one may receive reliable electricity throughout the day while the other experiences frequent outages and voltage fluctuations that prevent the effective use of appliances.

Similarly, access to clean cooking cannot be adequately measured simply by identifying the type of fuel used. The safety, affordability, convenience, efficiency and health impacts of cooking technologies are equally important considerations.

By measuring multiple dimensions of energy services, the Multi-Tier Framework provides a richer understanding of energy poverty and enables policymakers to identify where investments will have the greatest impact.

== What is the Multi-Tier Framework? ==

The Multi-Tier Framework (MTF) is a multidimensional methodology for measuring access to electricity and clean cooking. Developed by ESMAP, it evaluates the actual level of energy service experienced by households, enterprises and community facilities instead of relying solely on binary indicators such as whether an electricity connection exists.

The framework recognises that energy access is a continuum. Households may gradually improve their level of service over time as electricity becomes more reliable, affordable and capable of supporting a wider range of productive and domestic activities.

For electricity access, the framework evaluates households against a set of service attributes that together determine the quality and usefulness of electricity supply. Based on their performance across these attributes, households are assigned to one of six tiers ranging from Tier 0 (no meaningful access) to Tier 5 (high-quality electricity access).

This tier-based approach enables governments and development partners to monitor incremental progress towards universal access while identifying specific barriers that prevent households from achieving higher levels of energy service.

== The Seven Attributes of Electricity Access ==

The Multi-Tier Framework assesses electricity access using seven key attributes. Together, these indicators provide a comprehensive picture of the quality and usefulness of electricity services.

{| class="wikitable"
|+ Core Attributes Used to Measure Electricity Access
! Attribute
! Description
|-
| Capacity
| Measures whether the available electricity supply can support household and productive electricity needs.
|-
| Availability
| Assesses the number of hours electricity is available during the day and evening.
|-
| Reliability
| Evaluates the frequency and duration of power interruptions.
|-
| Quality
| Examines whether voltage remains stable enough to operate electrical appliances safely.
|-
| Affordability
| Considers whether electricity costs remain within acceptable household expenditure levels.
|-
| Legality
| Determines whether electricity is supplied through authorised and legal connections.
|-
| Health and Safety
| Assesses whether electricity installations and usage present unacceptable safety risks.
|}

Unlike traditional indicators, these attributes recognise that meaningful electricity access depends on service quality as well as physical infrastructure.

== Understanding the Energy Access Tiers ==

One of the defining features of the Multi-Tier Framework is its tier-based approach to measuring energy access. Rather than categorising households as either having electricity or not, the framework recognises that energy access improves progressively as the quality of service increases.

Households are classified into one of six tiers ranging from Tier 0 to Tier 5. Each successive tier represents an improvement in the capacity, availability, reliability, affordability and overall usefulness of electricity services.

{| class="wikitable"
|+ Electricity Access Tiers under the Multi-Tier Framework
! Tier
! Description
! Typical Characteristics
|-
| Tier 0
| No meaningful electricity access.
| No electricity service or an extremely limited service that cannot support basic household needs.
|-
| Tier 1
| Basic access.
| Supports only low-power devices such as LED lighting and mobile phone charging.
|-
| Tier 2
| Limited household electricity service.
| Can power lighting, fans, radios and televisions for several hours each day.
|-
| Tier 3
| Intermediate electricity access.
| Supports larger household appliances and enables small-scale productive activities.
|-
| Tier 4
| High-quality electricity service.
| Reliable electricity capable of supporting most household and business activities with minimal interruptions.
|-
| Tier 5
| Comprehensive electricity access.
| High-capacity, reliable, safe and affordable electricity comparable to modern power systems in advanced economies.
|}

This graduated approach enables governments to monitor progress beyond simple connection rates and identify the specific improvements required to raise households to higher levels of energy service.

== Measuring Access to Clean Cooking ==

The Multi-Tier Framework also provides a structured methodology for assessing access to clean cooking. Instead of focusing solely on the type of cooking fuel used, the framework evaluates the overall quality of cooking services experienced by households.

Key attributes considered include:

* exposure to household air pollution;
* efficiency of cooking technologies;
* convenience and time required for cooking;
* affordability of cooking fuels and equipment;
* safety of cooking practices;
* availability and reliability of fuel supplies.

This multidimensional assessment recognises that clean cooking is influenced by both technology and the broader context in which households prepare meals.

Improving access to clean cooking contributes not only to better health outcomes but also to gender equality, environmental protection and reduced pressure on natural resources.

== How the Multi-Tier Framework is Implemented ==

The Multi-Tier Framework is implemented through nationally representative household surveys designed to collect detailed information on electricity and cooking services.

Unlike conventional energy surveys, MTF surveys gather information on service quality, appliance usage, reliability, affordability and customer experiences. These data are then analysed using standardised methodologies to classify households into the appropriate energy access tier.

The survey process typically involves:

{| class="wikitable"
|+ Typical MTF Survey Process
! Stage
! Purpose
|-
| Survey Design
| Develop questionnaires covering electricity and clean cooking attributes.
|-
| Household Data Collection
| Gather information on energy access, appliance ownership and service quality.
|-
| Data Validation
| Verify consistency and completeness of survey responses.
|-
| Tier Classification
| Assign households to the appropriate electricity and clean cooking tiers.
|-
| Analysis and Reporting
| Produce national statistics and policy recommendations.
|}

This standardised methodology enables comparisons across countries while allowing national governments to monitor progress over time.

== Applications of the Multi-Tier Framework ==

Since its introduction, the Multi-Tier Framework has been applied in numerous countries to support evidence-based energy planning and investment.

Common applications include:

=== National Energy Planning ===

Governments use MTF survey results to identify underserved populations and prioritise investments in electricity infrastructure and clean cooking programmes.

=== Monitoring Sustainable Development Goal 7 ===

The framework supports global efforts to monitor progress towards ensuring access to affordable, reliable, sustainable and modern energy for all.

=== Electrification Programme Design ===

Utilities and rural electrification agencies can use MTF data to determine whether communities require grid extension, mini-grids or standalone energy systems.

=== Investment Planning ===

Development partners and financial institutions use MTF findings to guide investments towards areas where improvements in service quality will have the greatest social and economic impact.

=== Policy Development ===

The framework provides evidence that supports the formulation of national energy policies, subsidy programmes and regulatory reforms aimed at improving energy service delivery.

== Advantages of the Multi-Tier Framework ==

Compared with traditional energy access indicators, the Multi-Tier Framework offers several important advantages.

These include:

* measuring the quality of energy services rather than connections alone;
* identifying specific barriers that prevent households from achieving higher levels of access;
* supporting evidence-based policymaking;
* enabling comparisons across countries using a common methodology;
* improving monitoring of electricity and clean cooking services;
* encouraging investments that focus on meaningful energy access rather than infrastructure alone.

By recognising that energy access exists along a continuum, the framework provides a more realistic picture of progress towards universal access.

== Comparison with Traditional Energy Access Indicators ==

{| class="wikitable"
|+ Traditional Indicators versus the Multi-Tier Framework
! Traditional Indicators
! Multi-Tier Framework
|-
| Measures whether a household has an electricity connection.
| Measures the quality and usefulness of electricity services.
|-
| Produces binary results (connected or unconnected).
| Classifies households across six progressive tiers.
|-
| Limited consideration of service reliability.
| Explicitly evaluates reliability and availability.
|-
| Does not assess affordability or safety.
| Includes affordability, legality and safety.
|-
| Provides limited guidance for improving service quality.
| Identifies specific service gaps that require policy intervention.
|}

The Multi-Tier Framework therefore complements conventional electrification statistics by providing a more detailed understanding of how energy services contribute to human development.

== Lessons from a Decade of Multi-Tier Framework Surveys ==

More than a decade of applying the Multi-Tier Framework across multiple countries has provided valuable insights into how energy access can be measured and improved.

One of the most significant findings is that electricity connections alone do not necessarily translate into meaningful energy access. In many communities, households remain constrained by unreliable supply, limited service hours, poor voltage quality or electricity costs that restrict productive use. Measuring these dimensions helps governments identify service gaps that would otherwise remain hidden when relying solely on connection statistics.

The framework has also demonstrated that improvements in electricity access often occur gradually rather than through a single intervention. Households may progress from basic lighting services to higher tiers as electricity becomes more reliable, affordable and capable of supporting education, healthcare, income-generating activities and productive enterprises.

Experience from MTF surveys has strengthened national energy planning by enabling governments to prioritise investments based on actual service quality rather than infrastructure coverage alone. The resulting evidence has informed rural electrification programmes, utility planning, clean cooking initiatives and national energy strategies in several countries.

The continued application of the Multi-Tier Framework has also improved the availability of comparable international data, supporting better monitoring of global progress towards Sustainable Development Goal 7.

== Relevance for Africa ==

Africa continues to experience the world's largest electricity access deficit, while many households with electricity connections still face unreliable supply and limited service quality. These challenges highlight the importance of measuring not only whether electricity is available, but also whether it adequately supports household wellbeing and economic development.

The Multi-Tier Framework provides African governments, utilities and development partners with a practical methodology for assessing the effectiveness of electrification programmes and identifying communities requiring additional investment.

The framework can support:

* rural electrification planning;
* mini-grid and standalone solar deployment;
* utility performance assessment;
* clean cooking programme design;
* productive use of energy initiatives;
* monitoring progress towards SDG 7;
* evidence-based energy policy development.

By focusing on service quality rather than infrastructure alone, the framework encourages investments that deliver lasting improvements in people's quality of life.

== Challenges and Limitations ==

Despite its strengths, the Multi-Tier Framework presents several implementation challenges.

Comprehensive household surveys require significant financial resources, technical expertise and institutional capacity. Collecting reliable information across geographically dispersed populations can also be time-consuming.

Other limitations include:

* dependence on high-quality survey data;
* periodic rather than continuous data collection;
* variations in local socioeconomic conditions that may influence results;
* the need for regular survey updates to monitor changing energy access conditions.

Although these challenges exist, the framework remains one of the most comprehensive methodologies currently available for assessing energy access.

== Future Outlook ==

The growing emphasis on evidence-based planning is expected to increase the importance of multidimensional energy access measurement in the coming years.

Future development of the Multi-Tier Framework is likely to focus on:

* greater integration with national energy information systems;
* improved digital data collection techniques;
* stronger monitoring of productive uses of electricity;
* enhanced assessment of resilience and climate impacts;
* improved indicators for emerging energy technologies;
* broader application in policy evaluation and investment planning.

As countries accelerate progress towards universal energy access, the framework will continue to support more informed decision-making by helping policymakers understand not only where electricity is available, but also how effectively it meets the needs of households, businesses and public institutions.
