In March 2016, Florida regulators approved a new way for Gulf Power customers to support solar generation without installing panels on their homes or businesses.
The Florida Public Service Commission unanimously authorized Gulf Solar Energy Share, a five-year community solar pilot program. It was designed for customers who wanted electricity from a renewable source but could not use a conventional rooftop system because of cost, shade, property restrictions or rental housing.
Participants would pay an annual subscription fee connected to a planned solar facility near Milton. The electricity produced there would enter Gulf Power’s wider grid, while subscribers would receive a monthly credit on their utility bills.
The program offered greater access to solar energy, but it was not promoted primarily as a way to reduce electricity costs. Customers would pay a premium to support the development of a shared solar facility.
What Florida Regulators Approved
Gulf Power submitted its proposal to the Florida Public Service Commission on November 19, 2015. The utility requested approval for the community solar pilot, its subscription rates and the construction of an initial photovoltaic facility.
The commission approved the plan in March 2016. Its formal written order was issued on March 21, with the associated tariffs made effective from March 1.
The approval allowed Gulf Power to develop an initial solar array with a capacity of 1 megawatt. The company expected to build the facility near Milton in Santa Rosa County.
The pilot was intended to last five years beginning when the facility entered commercial operation. Gulf Power would then ask the commission to continue, modify or close the program.
During the pilot, the utility was required to report information including:
- the number and type of subscriptions;
- revenue collected through subscription fees;
- the amount of electricity generated;
- operating and program costs;
- credits paid to participants;
- customer participation and retention.
These reports would help regulators and Gulf Power evaluate whether customers were willing to pay for a shared solar option and whether the model could operate without transferring construction costs to people who did not participate.
How Community Solar Works
Community solar provides an alternative to placing photovoltaic panels on an individual building.
Instead of owning a private system, several customers subscribe to electricity generated by one larger solar facility. The power enters the regional grid rather than traveling directly from the shared array to a particular subscriber’s home.
The customer continues receiving electricity through the same utility lines. There is no separate solar cable, meter or physical connection between the subscriber and the off-site facility.
Participation is reflected through utility accounting. The customer pays the program fee and receives a bill credit based on the estimated value of the electricity produced by the subscribed portion of the facility.
This structure can make solar participation available to people who would otherwise face practical barriers. A renter generally cannot install permanent equipment on a landlord’s roof. A condominium owner may not control the shared building. Some homes are surrounded by trees or have roofs that face an unsuitable direction.
Other residents may support solar generation but cannot afford the initial cost of purchasing and installing their own system.
Who Could Participate
Gulf Solar Energy Share was intended to be available throughout Gulf Power’s Northwest Florida service territory.
Residential, commercial and industrial customers could subscribe. Availability would depend on the number of subscriptions supported by the initial facility, and enrollment was planned on a first-come, first-served basis.
A customer could purchase more than one subscription. The total, however, could not represent more electricity than the customer normally consumed during a year.
This restriction prevented a participant from purchasing a share far larger than the electricity used at the associated account. The pilot was intended to offset a customer’s conventional energy use, not create an investment that generated unlimited bill credits.
Subscriptions could move with a customer to another account inside Gulf Power’s service area. They could not be transferred to an unrelated person or used after the subscriber left the utility’s territory.
The Annual Subscription Cost
The standard subscription price was set at $99 per year.
Customers willing to make a five-year commitment would pay a reduced annual fee of $89. The longer agreement gave Gulf Power more predictable participation while offering subscribers a $10 yearly discount.
There were no rooftop installation or equipment maintenance expenses because Gulf Power would own and operate the shared facility.
Each subscription was expected to represent approximately 746 to 750 kilowatt-hours of annual solar generation during the first year.
For comparison, a household can consume considerably more electricity than that over a full year. One subscription would therefore offset only part of the typical customer’s annual use. Customers with higher consumption could purchase several subscriptions within the program limits.
How the Bill Credit Was Calculated
Subscribers would receive a credit on each monthly electric bill.
For the first year, Gulf Power estimated the credit at $2.11 per month for each subscription. Public descriptions of the program rounded the expected credit to between $2 and $2.50.
The credit was based on the utility’s avoided energy cost. This represented the estimated cost of electricity Gulf Power would otherwise need to generate or purchase if the solar facility were not producing energy.
The figure was not based on the full retail price charged to customers. It also did not equal the annual subscription fee.
At the original estimate, a customer paying $99 for one year would receive approximately $25.32 in total bill credits. The net annual premium would therefore remain around $73.68 before taxes or later adjustments.
A five-year subscriber paying $89 would face a smaller net premium, but the expected credits still would not eliminate the subscription cost.
The credit was to be recalculated each year because energy prices and projected solar production could change.
The Program Was Not Designed as a Discount Plan
The difference between the fee and the bill credit was an important part of the proposal.
Gulf Solar Energy Share did not promise that subscribers would save money. Participants were agreeing to pay part of the cost of developing and operating a solar facility.
The monthly credit recognized the value of the electricity generated, but it was not expected to recover the complete subscription fee.
Customers therefore needed to view the program as a voluntary environmental choice rather than a conventional cost-reduction product.
They would avoid the large initial expense and maintenance obligations associated with rooftop panels. In exchange, they would pay an annual premium without acquiring ownership of physical equipment.
This made the program simpler and more accessible, but it also meant subscribers would not receive the long-term financial benefits that may come from owning a productive rooftop system.
The Planned Milton Solar Facility
The initial solar farm was planned as a 1-megawatt facility near Milton.
Gulf Power estimated that construction would cost approximately $2.6 million. The estimate came from a competitive request for proposals issued in September 2015.
The winning proposal was selected after the company compared technical performance, projected energy production and construction costs.
Gulf Power expected the facility to generate about 2.15 million kilowatt-hours during its first year. Dividing that projected production among approximately 2,880 subscriptions resulted in about 746 kilowatt-hours for each subscription.
The facility would supply electricity to the general grid. Individual electrons could not be directed to specific subscribers, but each participant would financially support a defined share of the project.
Gulf Power also proposed adding more solar facilities if demand exceeded the capacity of the first array. Any expansion would depend on whether new subscriptions could support the cost of additional construction.
Why the Program Needed About 2,880 Subscriptions
The utility calculated that approximately 2,880 subscriptions would be needed to support the initial facility’s projected annual revenue requirement.
Gulf Power estimated that the project would require about $270,000 per year when construction, recurring capital expenses, insurance, maintenance and marketing were considered over the facility’s expected life.
The subscription target assumed that roughly half of the customers would pay the standard $99 annual rate and half would choose the five-year rate of $89.
At the time, Gulf Power served approximately 450,000 customers. Fully subscribing the facility would therefore require participation from fewer than one percent of the company’s accounts, although some customers could purchase several shares.
The utility believed this was achievable based on customer surveys and focus groups. Research commissioned before the filing found broad interest in solar energy, but a much smaller percentage of customers said they were definitely willing to pay a premium for it.
The pilot would test whether stated interest became actual enrollment once customers saw the fees and credits.
Who Carried the Financial Risk
Regulators examined what would happen if Gulf Power failed to sell enough subscriptions.
The company planned to begin construction after final approval rather than waiting until all shares had been sold. This removed uncertainty for interested customers but created a risk that subscription revenue might not fully cover the facility’s costs.
Gulf Power told the commission that its shareholders, rather than customers who did not join the program, would bear the risk of insufficient subscription revenue during the pilot.
The solar facility would still produce electricity for the entire grid if the program remained undersubscribed. Gulf Power reserved the right to return to regulators if circumstances later justified a different treatment of the asset.
The commission also required detailed annual reporting so that participation, costs and credits could be monitored.
Renewable Energy Certificates
Solar facilities can produce renewable energy certificates, commonly called RECs, in addition to electricity.
A REC represents the environmental attributes associated with a defined amount of renewable generation. These certificates can sometimes be sold separately from the physical electricity.
Under Gulf Power’s plan, the certificates associated with the community solar project would be retired on behalf of participating customers.
Retiring a certificate means it cannot later be sold or claimed by another party. This helped ensure that the renewable attributes supported by subscribers were not counted twice.
An Earlier Solar Subscription Had Failed
Gulf Solar Energy Share was not the utility’s first attempt to create a voluntary solar subscription.
In 1999, regulators approved a program that allowed Gulf Power customers to request 100-watt blocks of photovoltaic capacity for $6 per month.
Customers would not be charged until enough commitments existed to justify building a facility or purchasing solar electricity from another provider.
That threshold was never reached.
Participation peaked at 70 customers in 2005 and had fallen to 42 by the end of 2015. No facility was built, no solar electricity was delivered under the tariff and no participating customer was billed.
Gulf Power asked regulators to end the older tariff when it introduced the new community solar proposal. The company believed keeping both options would confuse customers and that Gulf Solar Energy Share had a more practical structure.
Different from Gulf Power’s Military Solar Farms
The community solar pilot was separate from three much larger Gulf Power projects approved in 2015.
Those utility-scale facilities were developed through partnerships involving the United States Navy and Air Force. Sites included NAS Saufley Field near Pensacola, NAS Whiting Field and Eglin Air Force Base.
Together, the military projects were expected to provide about 120 megawatts of generating capacity, far more than the planned 1-megawatt community facility.
The larger projects supplied solar electricity to Gulf Power’s broader system. Customers did not need to purchase individual subscriptions to benefit from their generation.
Gulf Solar Energy Share had a different purpose. It gave individual residents and businesses a way to voluntarily pay for a specifically identified community project.
Approval Did Not Mean Immediate Operation
The March 2016 decision authorized Gulf Power to move forward, but regulatory approval was not the same as completing the solar farm.
The company originally anticipated finishing construction during the third quarter of 2016. Subscribers would not be charged until the facility entered full commercial operation.
A University of Florida case study published in 2017 reported that the community solar program had not yet been implemented at the time of its research.
This distinction matters when reviewing the original announcement. The commission approved the proposed rates, project structure and pilot rules. It did not certify that the facility was already operating or that the subscription target had been reached.
The approval nevertheless showed that Florida regulators were prepared to test a community solar model for an investor-owned utility in Northwest Florida.
What the Pilot Was Intended to Learn
Gulf Power presented the program partly as a research opportunity.
The company wanted to learn how many customers would pay extra for solar electricity, how long they would remain enrolled and what type of marketing was needed to reach them.
It also wanted data on administrative expenses, customer satisfaction, facility performance and the financial sustainability of the subscription model.
These questions were important because community solar programs were still relatively new in many regulated utility territories.
Surveys could measure general support for renewable energy, but they could not reliably predict how many households would make an actual payment. A small pilot allowed the utility and regulators to test the idea without immediately developing a much larger facility.
A Transitional Moment for Solar in Northwest Florida
The approval came during a period when solar generation was beginning to occupy a larger place in Northwest Florida’s energy system.
Utility-scale projects were becoming less expensive, military installations were making land available for major arrays and customers were showing greater interest in renewable electricity.
Community solar attempted to address a specific gap. Rooftop panels were available to some property owners, while large utility facilities served the general grid. Renters, condominium residents and people with unsuitable roofs had few ways to connect their electric accounts with a particular solar project.
Gulf Solar Energy Share offered one possible solution. It removed the need for private equipment and opened enrollment to different classes of customers.
Its main limitation was financial. Subscribers would pay more than the value of the credits they received, making participation dependent on environmental priorities rather than immediate savings.
The Legacy of the 2016 Approval
Gulf Power later became part of Florida Power & Light. The companies legally merged in 2021, and the Northwest Florida utility began operating under the FPL name in January 2022.
By then, community solar programs had become a more established part of the national energy discussion. Utilities continued testing models that allowed customers to support shared renewable facilities without installing their own panels.
The 2016 Gulf Power proposal captured an early stage of that transition in Northwest Florida.
It showed both the appeal and the difficulty of community solar. The model could reach renters and customers with shaded roofs, but the subscription needed to balance affordability with the full cost of the facility. It could simplify access to renewable energy, but it could not guarantee that customers would save money.
Florida’s approval gave Gulf Power permission to test those questions through a limited five-year pilot.
For Northwest Florida customers, the program represented a new idea: supporting a local solar facility not by placing panels on their own property, but by purchasing a share of generation somewhere else on the electric grid.
