Nevada Irrigation District leverages hydro revenues to buy down 2027 water rate hike to 9%
Nevada Irrigation District, California · Meeting date: July 22, 2026 · Published: July 23, 2026
Following a delayed implementation that already cost $25 million in projected revenue, the district will transfer $8.6 million from its hydroelectric fund over five years to soften initial rate shocks for water customers.
Key points
- Staff proposed a flat 9% rate increase for raw water in 2027, keeping initial hikes below the maximum noticed Proposition 218 rates.
- The buydown relies on transferring $8.6 million in excess hydroelectric funds over the five-year rate period, starting with $1.27 million in 2027.
- The district is already absorbing a $25 million revenue loss due to a prior board decision delaying the new rates from July 2026 to January 2027.
- Looming capital pressures include the Scotts Flat Spillway replacement and an estimated $240 million in FERC relicensing requirements over the next 30 to 50 years.
Full report
The Nevada Irrigation District (NID) is moving to soften the blow of upcoming water rate increases by utilizing excess hydroelectric revenues to artificially buy down the initial rate hike to a flat 9% for 2027.
During a July 22, 2026, workshop, district staff presented a funding strategy that relies on transferring approximately $8.6 million from the hydroelectric fund to the water fund over the five-year rate period. For 2027 specifically, the district plans to transfer $1.27 million. The excess hydro funds were identified following the completion of the district's 2025 financial audit, which revealed higher-than-expected beginning fund balances for 2026 due to reduced expenditures and increased revenues.
The proposed 9% increase for raw water in 2027 is significantly lower than the maximum rates previously noticed under California's Proposition 218 process. Staff projected that holding the first year to 9% will necessitate flat 12.5% increases for the remaining four years of the rate cycle to maintain financial stability, though rates will be formally established on an annual basis. For treated water, the proposed 2027 rate will hold the reallocation between fixed and volumetric charges.
The decision to lower the 2027 rates compounds an existing revenue shortfall. The Board of Directors previously voted to delay the implementation of the new rates from July 1, 2026, to January 1, 2027. According to staff, that six-month delay will result in a projected decrease of $25 million in revenue collection over the five-year rate period.
Staff noted that this $25 million shortfall cannot be covered by the hydroelectric transfers and will instead be managed through cost savings and cuts to capital projects. To ensure unspent capital funds are not used on unnecessary projects, the district is currently reviewing its proposed 2027 capital expenditures to verify consistency with the rate study and regulatory requirements.
While the hydro fund transfer provides immediate rate relief, staff warned of significant looming financial pressures. The district faces an estimated $240 million in Federal Energy Regulatory Commission (FERC) relicensing requirements over the next 30 to 50 years. This will mandate infrastructure improvements, environmental mitigation, and increased stream flows that will reduce the amount of water available to sell. Additionally, the district's largest power purchase agreement is set to expire in 2032, introducing long-term revenue uncertainty.
Other major capital obligations include the Scotts Flat Spillway replacement. However, the district recently received regulatory affirmation that it can remove the upper plunge pool reconstruction from the project scope, opting instead for a new anchor system. This modification is expected to yield a net savings of between $5 million and $10 million. The district has also received a notice of intent for a $5 million Department of Energy grant for the spillway.
To help large agricultural customers adapt to the impending rate hikes and prepare for future droughts, the board also approved the formation of an Agricultural Water Efficiency Stakeholder Committee. The committee will explore grant opportunities and potential rule modifications to increase water use efficiency and reduce costs for high-volume irrigation users.
