United States: Grant County Projects Nearly $200 Million in Tax Revenue From Solar Developments

During a Nov. 4 budget meeting, Grant County Development Services Director Jim Brown outlined the potential financial benefits of seven renewable energy projects moving through various stages of development, including some already under construction.

Brown said changes to Washington's renewable energy tax structure under House Bill 1960 could create a significant long-term source of revenue for the county and other local public entities.

The projections represent potential future revenue, not money already collected or guaranteed to be received.

Brown told commissioners he had spent weeks reviewing his calculations, which account for the anticipated operating lives of the projects and their eligibility under the new tax structure.

The legislation, approved in 2026, establishes a revised system of state and local excise taxes based on the generating capacity of qualifying renewable energy facilities rather than solely on how much electricity they produce.

Under the legislation's final bill report , qualifying renewable energy facilities will be subject to a new tax structure that also changes their property tax treatment. The new excise taxes take effect in 2028.

Millions in additional revenue possible

Brown explained that the potential revenue goes beyond the excise taxes themselves.

Grant County could also collect millions of dollars in permit fees as additional solar developments move toward construction.

During the meeting, Brown presented estimates suggesting that permit-related collections could approach $12 million in 2027, depending on which projects move forward and when construction permits are issued.

However, those fees are not equivalent to unrestricted revenue available for general county spending.

Brown explained that certain permit revenues are deposited into a designated account, known as Fund 170, and distributed back to departments over the operating lives of the projects.

For a solar development expected to operate for 20 years, for example, the county could allocate approximately one-twentieth of the applicable permit revenue annually to help pay for ongoing administrative responsibilities.

Those responsibilities include inspections, development agreement amendments, reporting requirements and other work associated with monitoring the facilities.

The county also collects certain environmental mitigation payments that are restricted to purposes such as obtaining habitat mitigation credits or protecting land through conservation easements.

Brown told commissioners that Fund 170 already held approximately $3.5 million.

County officials also discussed whether the account was properly receiving investment earnings. During the meeting, the county treasurer confirmed that interest was being deposited into the fund.

New tax law changes financial outlook

The revised renewable energy tax system is particularly important for Grant County because of the number of large solar projects proposed or under development across the Columbia Basin.

Under the enacted legislation, the local renewable energy excise tax rate for qualifying solar facilities is $2,905 annually per megawatt of nameplate generating capacity. A separate state tax of $968 per megawatt also applies.

The law also establishes a system for directing portions of the proceeds toward local governments and community investments.

Revenue distribution and grant eligibility depend on the statutory requirements, including provisions involving local taxing districts and the Washington State Department of Commerce.

Brown said Grant County's existing development regulations appeared to satisfy the requirements necessary to receive the applicable local tax benefits.

He also discussed the possibility of additional funding through a state-administered grant program, although accessing that money could require further action by county commissioners.

Not every solar development will necessarily qualify for the same treatment. Some projects are already under construction, and Brown acknowledged that certain developers may not elect to participate under the revised structure.

The approximately $200 million projection also stretches across decades, meaning the amount collected in any given year would be considerably smaller.

Importantly, the estimate has not been independently verified against the individual projects' generating capacities, construction schedules and tax eligibility.

What will local residents receive?

The anticipated revenue raises a broader question about the long-term economic impact of solar development in Grant County.

Brown said he frequently hears questions about the direct benefits these projects provide to surrounding communities.

In addition to producing electricity, he pointed to the tax revenue, permit fees and other financial benefits generated by the developments.

Those revenues could potentially support public services and community investments, although the amount available to Grant County government itself will depend on how the money is distributed under state law.

The legislation establishes a local investment grant program administered by the Washington State Department of Commerce. It also contains provisions allowing qualifying rural counties to retain certain grant distributions rather than automatically passing them through to other local taxing districts.

Brown indicated that the county's financial projections could help inform future discussions with the Grant County Planning Commission and county commissioners about the community benefits associated with renewable energy development.

He also acknowledged that the figures depend on projects actually being built and operated.

County still working through financial planning challenges

The solar revenue projections come as Grant County commissioners are examining significant discrepancies in the county's preliminary 2027 budget.

During the same meeting, county officials discovered that certain planning and development revenues were not properly reflected in the preliminary budget spreadsheet.

Brown said the department's projected revenues were substantially different from those appearing in the budget documents, partly because solar permitting activity can create large but unpredictable increases.

The county has been reviewing its accounting classifications and budget preparation procedures to develop a clearer picture of revenues, expenditures and long-term financial obligations.

For now, Brown's projections suggest that renewable energy development could become an important component of Grant County's financial future.

However, the county has not publicly established during the reviewed discussion precisely how much of the projected $200 million would remain available for county government operations, how much would be distributed to other local entities, or how much would depend on future state grant awards.

The seven projects underlying Brown's estimate were not individually identified in the transcript reviewed by Source ONE News.

County officials have not announced a final allocation plan for the projected revenues.

As additional solar projects proceed through permitting and construction, the financial estimates could change substantially based on generating capacity, eligibility, project completion dates and the applicable tax distribution rules.

For Grant County, the figures highlight the potentially significant financial stakes associated with the region's continued expansion of large-scale renewable energy development.
