Electricity Market Structure in Keller
Keller is served by Oncor Electric Delivery for transmission and distribution services and participates in the ERCOT deregulated retail electricity market. Located in northern Tarrant County, Keller functions as an affluent residential suburb within the northwest DFW corridor, positioned between Fort Worth and the Alliance commercial development area.
Keller is classified within the ERCOT North Load Zone. The city's predominantly residential character — with large-lot single-family development and limited heavy commercial or industrial activity — produces a load profile concentrated in residential cooling demand during peak summer periods. Solar production timing in Keller aligns favorably with this peak demand window.
For additional context on Oncor Electric Delivery's role as the transmission and distribution operator in this market, see the Oncor Electric Delivery service territory analysis.
Solar Irradiation Context — Keller
Keller, Texas receives an estimated annual average solar irradiation in the range of 4.9 to 5.2 kWh per square meter per day, based on NREL National Solar Radiation Database reference data for the North Texas geographic zone. This translates to approximately 5.0 peak sun hours per day on an annualized basis, representing a moderately high solar resource consistent with the broader Texas solar production environment.
City-level irradiation data is applied in SunScore™ modeling as a primary energy yield input. No ZIP code-level or address-level irradiation claims are made on this page. Actual solar output at any specific property will vary based on roof pitch, azimuth, shading obstructions, and system configuration.
Utility Territory & Delivery Structure — Keller
Oncor Electric Delivery serves Keller as the regulated transmission and distribution operator under PUCT oversight. Oncor does not set retail electricity prices in the deregulated Texas market. Retail rates are established by competing retail electricity providers (REPs). The delivery charge component of a retail electricity bill — covering Oncor's transmission and distribution infrastructure — is regulated separately from the energy supply charge. SunScore™ projection modeling addresses the energy supply component of the retail bill only.
Retail Electricity Baseline — Keller (EIA 2024 Reference Year)
Residential electricity rate modeling for Keller references EIA Form 861 data for the 2024 reference year within the Oncor delivery territory in Tarrant County. The competitive retail electricity market in northern Tarrant County produces rate dynamics consistent with the broader deregulated North Texas pricing environment.
All rate references on this page derive from publicly available EIA Form 861 data for the 2024 reference year and represent historical average figures. They are not real-time rates, guaranteed future rates, or provider-specific quotes. Actual retail electricity prices in Keller vary by retail electricity provider, contract type, and enrollment date. Consumers seeking current rate information may consult the Power to Choose portal maintained by the Public Utility Commission of Texas.
Avoided Cost & Export Compensation Context — Keller
Avoided cost for Keller is modeled using the ERCOT North Hub wholesale-proxy baseline. Solar self-consumption in Keller's residential market avoids the applicable retail rate, while grid export is valued at wholesale-proxy levels substantially lower than retail. Given Keller's above-average home sizes and correspondingly higher electricity consumption profiles, self-consumption ratios occupy a significant weight in SunScore™ projection scenarios for this market.
In the ERCOT market, solar energy consumed on-site avoids the retail rate, while energy exported to the grid is compensated at or near wholesale-proxy levels — a materially lower value. SunScore™ projections distinguish between self-consumption and export scenarios. A detailed explanation of the avoided cost framework is available at Avoided Cost Explained.
Federal Incentive Layer — Keller (ITC 30% Reference)
The federal Investment Tax Credit (ITC), currently structured at 30% of eligible system cost under the Inflation Reduction Act as of the 2024 reference year, is available to qualifying homeowners in Keller who install eligible solar photovoltaic systems. This credit is non-refundable — it reduces federal income tax liability but does not generate a direct cash payment if the credit exceeds tax liability in the installation year. Unused credit may carry forward to subsequent tax years subject to applicable IRS rules.
The federal ITC is incorporated as an incentive layer input in SunScore™ modeled scenarios. GetSunScore does not provide tax advice. Homeowners should consult a qualified tax professional to assess eligibility.
Keller homeowners in Tarrant County are eligible for the Texas property tax exemption on qualifying solar installations and the federal ITC at 30%. Texas does not mandate retail net metering. Export compensation for Keller solar homeowners is governed by individual retail electricity provider contracts. DSIRE's 2024 reference year records document the applicable Texas incentive framework.
Modeled Projection Context — Keller
Keller's residential profile is characterized by above-average lot sizes, above-average home square footage, and a housing stock concentrated in the 1990s through 2010s construction era — conditions that collectively produce favorable solar siting parameters. The city's position in northern Tarrant County, at the interface of established Fort Worth-area suburbs and the high-growth Alliance industrial and commercial corridor to the north, means that Keller's residential distribution environment is distinct from both the denser urban core to the south and the more rural-transitional territory to the north.
SunScore™ projections for Keller use NREL irradiation data calibrated to the northern Tarrant County subregion and reflect residential consumption assumptions consistent with larger single-family home profiles.
All SunScore™ projections are non-binding modeled scenarios. They do not constitute financial advice, a solar installation quote, or a guaranteed savings figure. Full methodology documentation is available at Methodology, Data Sources, and Assumptions.
Solar Installation Pathway in Keller
Homeowners in Keller who have reviewed GetSunScore's modeled solar savings projection and wish to proceed with installation evaluation may do so through the standard residential solar qualification and contractor evaluation process.
Homeowners evaluating solar installation in Keller typically proceed through structured qualification and installer evaluation stages, beginning with a property assessment to confirm roof suitability, structural capacity, shading conditions, and utility interconnection eligibility under Oncor Electric Delivery's interconnection standards.
GetSunScore does not install solar systems, endorse specific solar contractors, or recommend providers. Qualified homeowners seeking installation evaluation may consult the installer directory referenced in GetSunScore's partner network documentation.

SunScore™ projections for Keller reference EIA Form 861 residential rate data for the 2024 reference year for the Oncor delivery territory in Tarrant County. These figures represent historical averages for this market. Actual retail rates in Keller vary by provider, plan type, and contract terms.
The SunScore™ Projection Engine applies NREL irradiation data for the Keller geographic zone, EIA-derived rate baselines for the 2024 reference year, and publicly available residential performance assumptions to generate a modeled, non-binding estimated savings scenario. Keller's larger average home sizes correlate with higher baseline electricity consumption, which is a relevant variable in self-consumption modeling. All projections are estimates; individual results will vary.
The Alliance commercial and industrial development area north of Keller contributes significant commercial load to the northern Tarrant County grid, but this does not directly alter residential solar economics for Keller homeowners. Residential solar savings remain a function of the retail rate avoided through self-consumption, governed by individual retail electricity contracts. SunScore™ applies residential rate baselines specifically for Keller projections. Full methodology detail is at /methodology.
