Revenue-Grade Meters: The Key to Unlocking SREC Value

Solar Renewable Energy Credits (SRECs) have become an important part of the solar energy landscape, offering solar system owners an additional revenue stream.

However, to participate in SREC markets, many states require the use of revenue-grade meters. Let's explore why these specialized meters are crucial for producing and selling SRECs.

‍

What Are Revenue-Grade Meters?

Revenue-Grade Meters (RGMs) are highly accurate power production meters that measure electricity output to within +/- 2% accuracy.

This level of precision is mandated by the American National Standards Institute (ANSI) rule C12.1-2008. RGMs are distinct from standard inverter meters or utility net meters, which may not meet the stringent accuracy requirements for SREC reporting.

‍

Why Are RGMs Necessary for SRECs?

The primary reason for requiring RGMs is to ensure the accuracy and integrity of SREC production.

SRECs represent the environmental attributes of solar energy generation, with one SREC typically equating to 1,000 kilowatt-hours (kWh) of solar electricity production. Given that these credits have monetary value and are traded in markets, it's crucial to have precise measurements of solar energy production.

State Requirements

Many states with SREC markets mandate the use of RGMs for solar systems participating in these programs. For example:

• New Jersey: All solar facilities must have an RGM and report meter readings to produce SRECs. These must be ANSI C12.1-2008 Certified
• Massachusetts: Facilities must report generation from RGMs to the Massachusetts Clean Energy Center Production Tracking System.
• Pennsylvania: Systems 15 kW DC or larger, or those interconnected after May 18, 2017, must use actual metered production.
• Maryland and Washington D.C.: Facilities 10 kW DC or larger must report monthly readings from RGMs.
• Ohio: Systems over 6 kW must report from an RGM.

Benefits of RGMs

1. Accuracy: RGMs provide the most precise measurement of solar energy production, ensuring fair compensation for SRECs.
2. Compliance: Using an RGM ensures compliance with state regulations for SREC production and reporting.
3. Credibility: The high accuracy of RGMs lends credibility to the SREC market, supporting its long-term viability.
4. Flexibility: RGMs allow participation in both net metering programs and SREC markets simultaneously, as they measure total production independently of energy consumption.

Installation and Costs

RGMs must be installed by licensed electrical contractors in compliance with local and national electric codes. The cost of installation can vary:

• Basic meter installations typically range from $350 to $900, with an average price of $645.
• More advanced meters with remote reading capabilities can cost between $1,250 and $2,500.

While these costs may seem significant, they are often outweighed by the potential revenue from SREC sales over the life of the solar system.

Conclusion

Revenue-grade meters are an essential component for solar system owners looking to participate in SREC markets.

While they represent an additional upfront cost, RGMs provide the accuracy and credibility necessary to unlock the full value of SRECs. As the solar industry continues to grow and evolve, the importance of precise energy measurement will only increase, making RGMs a wise investment for solar system owners.

By ensuring accurate reporting and compliance with state regulations, RGMs play a crucial role in supporting the growth of solar energy and the transition to a cleaner, more sustainable energy future. For solar system owners, these specialized meters are not just a regulatory requirement, but a key to maximizing the return on their solar investment through SREC sales.
