In 2023, the Arkansas 94th General Assembly passed Act 278, a landmark piece of legislation that significantly alters the state’s net metering policies. This article provides an overview of these changes, the implications for current and prospective solar energy users, and the importance of understanding net metering in promoting renewable energy development.
What is Net Metering?
Net metering is a billing arrangement that allows customers who generate their own electricity—typically through solar panels—to receive credit for the surplus energy they feed back into the grid. Under this system, the electricity produced can offset consumption from the utility, allowing users to reduce their electric bills. The goal of net metering policies is to encourage the adoption of renewable energy technologies by ensuring fair compensation for excess generation.

Key Changes Under Act 278
Grandfathering Provision
One of the most significant aspects of Act 278 is the “grandfathering” provision. Arkansans who install solar panels before September 30, 2024, will be able to lock in the current net metering rate of 1:1 for a period of 20 years. This means that those who invest in solar energy systems now can benefit from the existing compensation rates until 2040, regardless of future changes to the policy.
Transition to Net Energy Billing
After the grandfathering period ends, the state will shift to a new compensation model known as net energy billing or instantaneous netting. Under this model, customers will no longer be able to bank excess energy generated for future use. Instead, they will consume their generated electricity in real time and receive compensation for any surplus energy sent back to the grid based on avoided costs, which are typically lower than retail prices.
Implications of the Policy Changes
Compensation Structure
The transition to net energy billing means that while customers can still export excess energy to the grid, the compensation they receive will be significantly lower. This could make solar installations less economically attractive for some users. Under the new structure, utilities will pay for excess generation at a rate that reflects the avoided costs rather than the retail rate, which may lead to a reduction in financial incentives for future solar investments.
Credit Carry Forward
In Arkansas, customers can carry forward credits from excess generation until they decide to cash out, which is a flexibility not offered in all states. However, this will change once the new rules take effect, as the ability to bank energy for future billing cycles will be eliminated.
Capacity Limits
The new policies maintain specific capacity limits for residential and commercial installations, which are set at 25 kilowatts (kW) and 300 kW, respectively. Additionally, third-party financing is permitted for non-ownership solar arrangements, broadening access for schools and municipalities.
Variations in Net Metering Policies
Net metering policies differ widely across the United States, affecting capacity limits, compensation rates, and credit carry-forward periods. In Arkansas, the Arkansas Public Service Commission (APSC) has set a framework that includes grandfathering existing agreements and allows for meter aggregation—a key advantage for agricultural customers who operate multiple meters.
Meter Aggregation
Meter aggregation permits users with multiple electric meters to aggregate their energy consumption, enabling a single solar system to offset electricity usage across various locations. This is particularly beneficial for farmers and businesses with geographically dispersed operations, allowing them to optimize their solar investments without the need for physical connections between the generating system and the meters.
Arkansas’ Key Solar Incentives: A Breakdown
The changes brought about by Act 278 present both opportunities and challenges for Arkansas residents considering solar energy. Those who act before the September 2024 deadline can benefit from the more favorable grandfathering provisions. However, understanding the implications of the new net energy billing system is crucial for long-term financial planning. As policies evolve, staying informed about net metering and its impact on renewable energy investments will be vital for maximizing benefits and promoting sustainable energy solutions in Arkansas.
