Delaware PSC Regulation 3008 Renewable Energy Portfolio Standard and SREC Guide

Key Takeaways

• Delaware PSC Regulation 3008 mandates increasing solar PV carve-outs for electric companies, reaching 10% by 2035.
• Solar Renewable Energy Credits (SRECs) are tracked via PJM-EIS GATS and have a 3-year compliance lifespan, tolled by the SEU.
• Significant multiplier credits are available for customer-sited generation, including 300% for pre-2015 systems and 10% bonuses for local content.
• Understanding these regulations is crucial for compliance and maximizing renewable energy incentives in Delaware.

What is Delaware PSC Regulation 3008 and how does it affect solar energy?

Delaware Public Service Commission (PSC) Regulation 3008 (26 Del. Admin. C. 3008) is the official regulatory framework for the Renewable Energy Portfolio Standard (RPS) and Solar Renewable Energy Credit (SREC) generation in Delaware. It mandates that Commission-regulated electric distribution companies (CRECs), such as Delmarva Power & Light, source a minimum percentage of their retail electricity sales from eligible renewable resources, including specific solar photovoltaic (PV) carve-outs. This regulation drives the demand for solar energy by requiring utilities to purchase SRECs to meet their compliance obligations.

Navigating RPS Compliance and SREC Generation

Understanding the mechanisms for RPS compliance and SREC generation is essential for solar energy stakeholders in Delaware. This involves registering systems, tracking generation, and ensuring proper credit application.

Diagnosis Steps for Regulatory Compliance

1. Verify System Registration: Ensure your customer-sited generation system is registered in PJM-EIS GATS. This is necessary to mint 1 SREC per 1 MWh of verified solar generation. Without proper registration, SRECs cannot be created or tracked.
2. Monitor SREC Lifespan: Track the compliance lifespan of your SRECs. SRECs may be dated no earlier than three (3) years prior to the beginning of the current Compliance Year. This period is tolled when the SREC is held by the Sustainable Energy Utility (SEU), preventing premature expiration.
3. Assess Multiplier Eligibility: Review eligibility for specialized multiplier credits. For example, systems installed on or before December 31, 2014, receive a 300% credit. An additional 10% credit is available if a minimum of 50% of the equipment cost relates to Delaware-manufactured equipment, and another 10% if the facility is installed with a workforce consisting of at least 75% Delaware residents.
4. Confirm Industrial Customer Exemption: If applicable, verify that industrial customers with peak demand exceeding 1,500 kilowatts have been acknowledged by the Commission as exempt from RPS compliance obligations. This prevents improper assessment of non-bypassable surcharges.
5. Review Compliance Reporting: For CRECs, ensure annual RPS compliance reports are filed within 120 days of the compliance year end (May 31). This report details the fulfillment of the mandatory RPS targets.

Compliance Issues and Solutions

Understanding Regulatory Frameworks and Incentives

Delaware's RPS and SREC program is designed to promote renewable energy development through specific mandates and incentives. This section details the key components of the regulation, including carve-out schedules and multiplier credits.

RPS Carve-Out Schedules

Delaware PSC Regulation 3008 mandates a progressive increase in the percentage of electricity sales that must come from solar PV. These targets are part of a broader Renewable Energy Portfolio Standard.

• 2024 Solar RPS Carve-Out: 3.25% solar PV minimum (24.00% total eligible renewable resources).
• 2025 Solar RPS Carve-Out: 3.50% solar PV minimum (25.00% total eligible renewable resources).
• 2026 Solar RPS Carve-Out: 3.75% solar PV minimum (25.50% total eligible renewable resources).
• 2030 Solar RPS Carve-Out: 5.00% solar PV minimum (28.00% total eligible renewable resources).
• 2035 Solar RPS Target: 10.00% solar PV minimum (40.00% total eligible renewable resources).

These percentages represent the minimum amount of electrical energy sales from solar photovoltaics that Commission-Regulated Electric Companies (CRECs) must achieve.

Multiplier Credits for Solar Installations

To further incentivize specific types of solar development, Regulation 3008 offers multiplier credits:

• Pre-2015 Customer-Sited Multiplier: A 300% credit is applied for energy from customer-sited solar photovoltaic systems physically located in Delaware, provided they were installed on or before December 31, 2014.
• In-State Manufacturing Multiplier: An additional 10% credit is granted if a minimum of 50% of the cost of the renewable energy equipment, including mounting components, relates to Delaware-manufactured equipment.
• In-State Workforce Multiplier: Another 10% credit is available if the facility is constructed and/or installed with a workforce consisting of at least 75% Delaware residents, or if the installing company employs a minimum of 75% Delaware residents.

These multipliers significantly increase the value of SRECs generated by eligible systems, enhancing their economic viability. For more information on related policies, you can refer to our guide on Delaware PSC Net Metering and Delmarva Power.

SREC Tracking and Tolling

SRECs are tracked and minted through PJM-EIS GATS. Each SREC represents 1 MWh of verified solar generation. SRECs have a compliance shelf life of three (3) years prior to the beginning of the current compliance year. However, this three-year period is tolled during any time that a renewable energy credit or solar renewable energy credit is held by the Sustainable Energy Utility (SEU), preventing their expiration.

Industrial Customer Exemptions

Industrial customers whose peak demand is in excess of 1,500 kilowatts and have been acknowledged by the Commission as having their load exempted from RPS compliance obligations are not charged the non-bypassable RPS compliance cost. This exemption is outlined in 26 Del.C. §353(b), Section 1.0, and subsections 2.2.1 and 2.2.2 of the regulation.

Safety: Ensuring Compliance and System Integrity

While this guide focuses on regulatory compliance, the underlying solar installations involve electrical systems. Always prioritize safety when dealing with any physical aspect of a solar energy system.

• Electrical Isolation: Always verify electrical isolation and perform lock-out tag-out procedures before servicing revenue-grade SREC generation meters or any electrical components.
• Metering Accuracy: Maintain accurate electrical metering records. This prevents over-generation penalties and ensures compliance with PJM settlement rules, which are critical for SREC minting.
• Grid Interconnection: Ensure all customer-sited grid connections comply with Delmarva Power interconnection standards. Improper connections can lead to safety hazards and regulatory non-compliance.

When to call a technician instead

While understanding the regulatory framework is important, the physical installation and maintenance of solar energy systems require specialized expertise. If you encounter issues with your solar PV system's operation, metering, or grid interconnection, it is best to consult a qualified solar technician or electrician. Attempting repairs or modifications without proper training can be dangerous and may void equipment warranties or regulatory certifications.
