Understanding net metering, gross metering, and net billing: Pakistan needs sustainable practices

The Renewable Energy Revolution in Pakistan: A Deep Dive into Net Metering and Gross Metering

The recent buzz around gross metering has reignited discussions on renewable energy, a crucial subject as the world increasingly shifts towards sustainable power sources. With the global commitment to triple renewable energy pledged at COP28, adopting renewable energy is paramount for sustainable development, particularly in Pakistan.

The current state of Renewable Energy in Pakistan

Our nation grapples with energy shortages and pressing environmental concerns, with renewable energy currently making up only 5% of our energy mix (excluding hydropower). Pakistan has set an ambitious target to achieve 60% renewable energy in its energy mix by 2030 to reach net zero emissions.

Surge in Net-Metering Consumers

As of June 30th, 2023, the total number of net-metering consumers in Pakistan surged to around 56,000, marking a 50% increase compared to the previous year (NEPRA + RF calculations). In fiscal year 2022–23, net metering generated 482 gigawatt-hours, highlighting an impressive 220% year-on-year growth. This figure does not account for those who are entirely off-grid and whose contributions go unmeasured.

Understanding Metering Mechanisms

Net Metering

Thanks to net metering, customers can use the electricity their in-home solar systems produce. Any surplus electricity is sent to the grid, and consumers receive credits or monetary compensation at an agreed-upon rate (currently Rs19.32/kWh). This system offers higher savings, simplified billing, and energy independence. However, it impacts utility revenue and comes with significant infrastructure costs.

Gross Metering

Gross metering mandates that consumers sell all the electricity they generate to the grid at a predetermined tariff while buying all their electricity from the grid at the retail rate. These two transactions (selling and buying) are separate, with no generation offsetting against consumption. Consumers are paid a fixed rate for their electricity production but purchase their required electricity at a higher standard rate. This diminishes the economic benefits of installing renewable energy systems, as the lack of immediate reduction in electricity bills makes the financial payback period longer and less attractive.

Net Billing

Net billing is similar to net metering but values the excess electricity sent to the grid differently. Under net billing, the energy exported to the grid is credited at a price different from the retail rate, often lower. The consumer’s bill is calculated based on net consumption, but the credits are applied separately.

The Impact of Net Metering on Pakistan’s Renewable Energy Landscape

Net metering has significantly shaped Pakistan’s renewable energy landscape. It incentivizes individual investments in solar panels, allowing consumers to reduce their electricity bills and promote a shift to renewable energy. This approach has made solar power more attractive and helped alleviate the energy crisis by adding more distributed generation capacity to the grid. The adoption of net metering has encouraged private investment in renewable energy, fostering a market essential for long-term sustainability.

Challenges and Considerations

Conversely, while guaranteeing a steady income for the electricity generated, gross metering disincentivizes energy conservation since consumers buy all their energy at retail rates. This system can be less appealing to potential investors because it does not provide the direct benefit of reduced energy bills, making the return on investment longer and less predictable.

For Pakistan to effectively transition to renewable energy, policies, and mechanisms must strongly incentivize private and individual investments instead of subsidizing thermal energy. Policymakers must carefully consider the implications of these metering systems rather than pressuring people to shift completely off-grid. If households can afford to install solar panels, they might also invest in batteries to go entirely off-grid.

Ensuring Support for Renewable Energy Growth

Policymakers aim to reduce the cost of buying solar energy from consumers, potentially applying such tactics to push them to agree to these terms. Considering the international landscape, ensuring support rather than hindrance to renewable energy growth in Pakistan is crucial. Maintaining stability in the energy market while avoiding further burdens on consumers is essential for a sustainable energy future in Pakistan.

Conclusion

Pakistan’s journey towards a sustainable energy future hinges on effective policies and incentives encouraging private and individual investments in renewable energy. By understanding the different metering mechanisms and their impacts, Pakistan can better navigate the complexities of its energy landscape and make strides towards its ambitious renewable energy targets.
