Do Your Research

Before you consider installing solar, make sure your building is energy efficient. Maximizing your property’s energy efficiency first helps ensure the electricity generated by your solar system is not lost through leaky duct work, inadequate insulation or an inefficient heating and cooling system.

The EnergyWise for Your Business Program can help electric business customers replace aging, inefficient equipment and systems with energy-efficient technologies. Through financial incentives and technical assistance, our program offerings support prescriptive, custom and small business energy efficiency measures.

We also recommend that you read A Solar Guide for South Carolina Business Owners for helpful information about the decision-making process for installing solar and the many factors to be considered before, during and after installing panels on your business.

Consider Tax Credits

Tax credits for rooftop installations can help offset the cost of solar investments. The 30% Investment Tax Credit (ITC) for commercial projects has been be extended until December 31, 2019 in its current form. After that, projects that start construction in 2020 and 2021 will receive 26 percent and 22 percent, respectively. All projects must be completed by 2024 to obtain these ITC rates. Please consult your tax advisor.

Not all properties are suitable for rooftop solar. Before you make the commitment to install, make sure that your building (roof structure, capacity, pitch, shading, etc.) is suitable for solar panels. You might also consider a ground-mounted solar system on your property. See A Solar Guide for South Carolina Business Owners.

While we are unable to offer assistance, we recommend working with a certified tax adviser to determine your eligibility.

The company is offering non-residential customers options to receive energy or bill credits for installing solar under its Net Energy Metering program. We do not offer cash rebates, upfront incentives, or financing.

While A Solar Guide for South Carolina Business Owners addresses many of the factors that should be considered before, during and after solar installation, it is not a comprehensive technical, design or installation guide. You should always consult with an experienced solar contractor to determine the right system for your business.
For inquires pertaining to your solar system, contact your solar contractor. After reviewing this website, if you have additional questions specific to Dominion Energy’s solar programs, please email us at SCRenewableEnergy@DominionEnergySC.com or call us at 1-800-251-7234.

Renewable Energy Programs

Net Energy Metering (NEM)

For every kWh generated, your business will offset its energy usage and receive an energy credit for excess generation equal to its current electric service rate.

Renewable Energy Programs

  • Offset/Sell: Customer offsets usage at retail and then receives Small Power Production, Cogeneration Rate for any excess generation.
  • Offset Only: Customer offsets usage at retail. No credit for excess energy sent back to grid.
  • Buy All/Sell All: Customer purchases energy under the current rate and sells all generation to utility at the Small Power Production, Cogeneration Rate.

Questions & Answers

Net metering provides one way for customers who generate their own renewable electricity to reduce the power they need for their business. You will receive a credit that you can rollover for any excess energy that you generate.
  • Offset/Sell: Customer offsets usage at retail and then receives Small Power Production, Cogeneration Rate for any excess generation.
  • Offset Only: Customer offsets usage at retail. No credit for excess energy sent back to grid.
  • Buy All/Sell All: Customer purchases energy under the current rate and sells all generation to utility at the Small Power Production, Cogeneration Rate.

There are many renewable energy options (solar, wind, hydro, even biomass), so there is no set price. The U.S. Department of Energy’s website is a good starting point. You can also use the PV Watts tool on NREL's website.

National Renewable Energy Laboratory (NREL)

In February 2015, we filed a comprehensive set of Distributed Energy Resource (DER) programs with the Public Service Commission of South Carolina to offer customers incentives that would promote the installation of solar in South Carolina. The Commission approved the application on July 15, 2015.

A Bill Credit Agreement program was approved providing incentives for business customers who generated solar energy and put it on Dominion Energy SC's grid. The amount of the incentive is based on the size of the solar system. Qualifying tax exempt customers receive a higher incentive because they cannot take advantage of federal or state tax credits.

In addition, qualifying tax exempt customers will have the opportunity to participate in Dominion Energy-managed Community Solar farms starting in mid-2016.

There is no specific deadline for participating in the company's Bill Credit Agreement (BCA); however, Dominion Energy South Carolina has requested that the Public Service Commission suspend its BCA program indefinitely for new participants. If granted, Dominion Energy SC proposes that customers who, prior to the issuance date of the Commission’s order, have applied and been approved by Dominion Energy SC to participate in the BCA program, properly executed an interconnection agreement, and made all payments and financial security-related requirements set forth in the interconnection agreement (if applicable) be permitted to proceed as a BCA program participant – provided their system also be interconnected within 12 months of the Order. A ruling on this request is expected by April 30, 2017, and if approved, will take effect immediately. No customer applications will be approved after this date.
Customers are not eligible to participate in Net Energy Metering Plus if they also currently participate in PaCE. Under its Distributed Energy Resource programs, Dominion Energy South Carolina assumes ownership of the renewable energy credits (RECs). If you participate in PaCE, the organization retains the energy credits based on your renewable energy generation.

How to Find Solar Contractors

Always use a professional, licensed contractor to install your solar electric system. While Dominion Energy does not endorse any contractors, here are some resources to consider:

Buying vs. Leasing

There are several factors to consider when deciding whether to buy or lease your system.

  • Buying a renewable energy system from a contractor or manufacturer means paying for it up front or financing your purchase through a bank loan. You own the entire solar system and federal and state tax credits may be available. Please consult with your tax advisor.
  • Leasing allows you to "rent" the renewable energy system for a set period of time. Generally, you pay a fixed monthly rate no matter how much energy the system produces each month. This rate may escalate each year during the term of the lease. Because you do not own the system, federal and state tax credits may not be available. Please consult with your tax advisor.
IMPORTANT NOTE: If you purchase or lease your solar system by 5/31/2021, please note that the current Net Energy Metering tariff has been approved through 5/31/2029 – after which the cost structure for your customer generation will change.

Dominion Energy Equipment Requirements to Review with Your Installer

Customers can offset up to 100% of their electrical usage without exceeding 20 kW for residential customers and 1,000 kW for non-residential customers. Dominion Energy uses a customer’s annual electric usage and a capacity factor of 1,531 to determine the amount of solar a customer can have.

FORMULA:

CUSTOMER USAGE (kWh)
_____________________________________________________________________

(365 DAYS * 24 HRS PER DAY * CAPACITY FACTOR * DC/AC CONVERSION)

EXAMPLE: 

ANNUAL CUSTOMER USAGE - 10,717 kWh

10,717/(365*24*0.1531*1.1) = 7.26

7.26 kW - MAXIMUM SYSTEM SIZE

Renewable Energy customers who interconnect on or after January 1, 2015 are eligible to receive an annual bill credit if their solar generation exceeds their usage. The value of any bill credit/payment you receive could be treated as income. Consult with your tax advisor for more information.
