Pakistan Household Use of Commercial Energy Summary

Core Content

This report, prepared by Masami Kojima for the Energy Sector Management Assistance Program (ESMAP), analyzes the household use of commercial energy in Pakistan between 1994 and 2001. It includes data from four household expenditure surveys and insights from focus group discussions and individual interviews conducted in 2004 and 2005. The study explores how changes in energy availability and pricing have influenced household energy choice, consumption, and expenditures.

Main Purpose

• To examine the impact of changing energy availability and price levels on household energy use and expenditures.
• To provide insights for energy sector policy development and poverty and social impact analysis.

Key Findings

1. Energy Sector Overview

• ESMAP is a global technical assistance program managed by the World Bank and supported by various bilateral and private donors.
• ESMAP's focus areas include energy security, renewable energy, energy poverty, and market efficiency and governance.
• The report highlights the role of ESMAP in generating and disseminating knowledge to support development goals.

2. Household Expenditure Trends

• Between 1994 and 2001, household expenditures on energy increased modestly in real terms by 6%.
• The percentage of households using natural gas, LPG, and electricity rose, while the percentage using kerosene declined.
• Electricity remained the most expensive energy source, with an average monthly expenditure of Rs 320 in 2001, followed by natural gas at Rs 240.

3. Energy Use Patterns

• The dominant household energy mix shifted from kerosene-biomass-electricity in 1994 to biomass-electricity in 2001.
• Natural gas-electricity became the second most prevalent energy mix in 2001, up from fourth in previous surveys.
• Biomass use remained relatively stable, but the percentage of households using free biomass increased, especially among the poor.

4. Provincial Differences

• Punjab: Electricity and natural gas were the most widely used, with higher consumption and expenditure levels.
• Sindh: Similar trends were observed, with electricity and natural gas dominating.
• Northwest Frontier Province (NWFP): Biomass and electricity were the primary sources, with lower usage of commercial fuels.
• Balochistan: Biomass use was the highest, followed by electricity and natural gas.
• Other Areas: Smaller populations and different energy usage patterns were noted.

5. Affordability and Price Trends

• Electricity and natural gas prices increased faster than the CPI, affecting affordability.
• Natural gas was perceived as affordable, while kerosene became too expensive for many households.
• The use of free biomass increased in response to rising commercial energy prices, indicating a shift in household behavior.

6. Survey Methodology

• The study analyzed four household expenditure surveys (1994, 1997, 1999, 2001) and included focus groups and individual interviews.
• The surveys excluded expenditures on durable goods but included imputed values for freely acquired consumption goods.
• Focus groups and interviews were conducted in urban and rural areas across Punjab, Sindh, and Balochistan.

Main Views

• Energy Access and Uptake: Access to electricity, natural gas, and LPG increased over time, with the poorest households showing the most significant uptake of free biomass.
• Price Impact: Rising energy prices led to reduced use of kerosene and increased reliance on free biomass.
• Policy Implications: The findings suggest that energy pricing policies and market reforms have a direct impact on household behavior and energy consumption patterns.
• Regional Variations: Urban areas showed greater adoption of commercial energy sources, while rural areas relied more on biomass and kerosene.

Key Information

• Energy Sources: The primary sources of energy include electricity, natural gas, LPG, kerosene, and biomass.
• Affordability: Households in lower income brackets found natural gas and biomass more affordable, while kerosene became less accessible.
• Survey Data: The data shows a shift in energy mix over time, with electricity and natural gas becoming more prevalent.
• Price Trends: Prices for electricity, natural gas, kerosene, and LPG increased faster than the CPI, which affected household expenditures.
• Focus Group Insights: Focus groups provided qualitative data on energy affordability, service quality, and commercial malpractice, highlighting the challenges and perceptions of households regarding energy use.

Conclusion

The study reveals that household energy choices and consumption patterns in Pakistan have evolved significantly over the past decade, influenced by changes in energy pricing and availability. The increasing use of commercial energy sources like electricity and natural gas, coupled with the decline in kerosene usage, indicates a shift towards more modern and potentially cleaner energy options. However, the continued reliance on free biomass, especially among the poor, suggests that economic constraints and accessibility issues still play a critical role in shaping energy use. These findings are essential for informing energy sector policies and poverty alleviation strategies.
