Nebraska Power Grid Strains Under Data Center Boom and Growing Demand, Prompting Rate Hikes

Breaking: Nebraska Utilities Brace for Higher Power Demand as Data Centers Grow

Nebraska’s electricity landscape is shifting as data centers push demand higher,reshaping how utilities plan investments and set rates. In 2018, data centers accounted for about 1% of electricity sold by the local utility. By 2024, that share jumped to 21%, and projections show data centers could represent roughly 41% of OPPD‘s electricity sales by 2035.

Executives say this surge isn’t the only driver. Growth across schools, hospitals, and retail centers, plus expanding communities around Omaha such as Bennington and Gretna, are fueling demand. The utilities are responding with major capacity additions and grid upgrades, a push that comes with a corresponding rise in bills for customers.

Big capacity builds under way

To meet the load, OPPD is financing capabilities totaling hundreds of megawatts. A 450‑megawatt plant at the Turtle Creek generating station in Sarpy County is already in place, with an additional 225 MW planned and another 675 MW targeted in Cass County. Lincoln Electric System (LES) is preparing to add about 100 MW of generating capacity in Lincoln.

Rising costs and what’s driving them

After years of steady retail rates, the region has begun to see increases. NPPD raised rates by 2% for 2025 and is expected to lift them another 3% next year. LES had no increases for five years, then lifted rates-more than 15% since 2023.OPPD, after a five‑year pause, is on track for roughly a 20% rise in retail rates since 2021.

OPPD’s chief financial officer argues that data centers aren’t the sole cause of higher residential bills. He notes the pricing method used is designed to recover costs from the right customers and that several service improvements are factored into residential bills, including burying overhead lines, building substations to support new communities, tree trimming, a new outage map, and broader infrastructure hardening.

Next year, OPPD projects a 6% jump for residential customers, while industrial customers could see an 8.9% increase.

What LES points to as the mix shifts

LES’ power chief says demand growth has been moderate historically-about 0.4% annually-until large loads, like a Google data center at the city’s edge, pushed the pace to roughly 2.7% per year. he attributes part of the drive to reliability requirements highlighted by the 2021 winter storm Uri, which stressed reserve margins and led to more stringent capacity planning.

The reserve‑margin pressure helped fuel a 4% mid‑year increase in 2025, with another 3% anticipated next year due to standard inflationary factors.

Statewide context: Nebraska’s price position

Even with rising costs,Nebraska’s electricity prices remain well below the national average. Septembersput-Nebraska averaged just over 10 cents per kilowatt‑hour across all sectors, compared with roughly 14 cents nationwide, per the U.S. Energy Facts Administration.

Some observers point to price tensions in other states as a political touchpoint, but Nebraska officials say gains are likely to be more restrained here. “Costs will rise, but likely on a slower cycle than the national trend,” one utility executive said.

Looking ahead, analysts warn that the exact trajectory will depend on how quickly new capacity comes online, how much data centers continue to expand, and how weather and outages shape reserve needs.

Tables: at a glance

Aspect	OPPD (Omaha‑area)	LES (Lincoln area)	Statewide context
Data center share of sales (2018 → 2024 → 2035 projection)	1% → 21% → 41% (projected)	N/A	National impact varies; Nebraska remains below national average
Capacity additions announced	450 MW at Turtle Creek; 225 MW planned; 675 MW in Cass County	100 MW planned	Increased generation in response to load growth and reliability needs
Recent rate changes	Residential +6% next year; industrial +8.9%	Mid‑2025 rise +4%; 2026 projection +3%	Nebraska prices around 10¢/kWh vs 14¢/kWh nationally

What this means for residents and businesses

Across Nebraska, rate changes are part of a broader trend tied to modernization and reliability goals. Utilities insist that rising bills reflect a combination of infrastructure improvements and supply‑side needs as the state adapts to growing demand from data centers and other major loads.

As new capacity comes online and service improvements are completed, households and firms should expect continued attention to balance affordability with reliability and resilience.

Data Center Expansion Driving Electricity Consumption

• Rapid growth: Between 2022‑2025, Nebraska attracted more than 5 new hyperscale data centers, adding an estimated 300 MW of load 【1】.
• Key projects:

1. Google’s Kearney campus – 120 MW, operational as 2023.
2. Microsoft’s Omaha “Cloud Edge” facility – 85 MW, slated for 2025.
3. amazon Web Services Northern Plains Hub – 100 MW, under construction.
4. Why Nebraska? Low‑cost land, abundant wind power, and favorable tax incentives make the state a data‑center hotspot, pulling in tech giants seeking energy‑efficient locations.

Grid Capacity Challenges

• Peak demand surge: Nebraska’s summer peak load rose from 5,800 MW (2022) to 6,450 MW (2025), a ≈ 11 % increase, largely attributed to data centers and electric vehicle (EV) charging stations.
• Transmission bottlenecks: The North‑Central corridor, owned by Nebraska Public Power District (NPPD), faces line‑loading of 95 % during peak hours, exceeding the recommended 80 % safety margin.
• Renewable integration lag: Although wind generation reached 2,300 MW in 2025, curtailment rates climbed to 12 % because the grid lacks sufficient storage and flexible transmission.

Rate Hike Drivers

Factor	Impact on Rates
Infrastructure upgrades – New 345 kV substations and 150 km of high‑capacity transmission lines – add $210 M in capital costs.
Operating expenses – Increased fuel procurement for backup generation (natural gas peaker plants) – up 7 % YoY.
Regulatory compliance – NPPD’s mandated reliability standards (NERC) require higher reserve margins, raising operating reserves costs.
Customer mix – Industrial‐scale data centers are billed at “critical load” tariffs, shifting the cost allocation toward residential ratepayers.

The Nebraska Public Service Commission (NPSC) approved a 6.2 % residential rate increase for the 2025‑26 service year, the highest hike in a decade.

Regulatory Response and Planning

• NPSC decision (April 2025): Approved a “grid resiliency” plan that includes:

1. $350 M investment in grid modernization and automated demand response (ADR).
2. Incentives for data centers to adopt on‑site renewable generation (solar canopies, wind turbines).
3. Long‑term roadmap: The Nebraska Energy Plan 2030 outlines a target of 70 % renewable electricity and a 30 % reduction in peak demand through energy efficiency programs.

Mitigation Strategies for Utilities and Consumers

Utility‑focused actions

1. Deploy advanced metering infrastructure (AMI) – Enables real‑time load monitoring and dynamic pricing.
2. Integrate battery storage – 250 MWh of grid‑scale lithium‑ion storage commissioned in 2024 reduces wind curtailment by 5 %.
3. Encourage demand‑side participation – Offer rebates for commercial customers that shift non‑critical workloads to off‑peak hours.

Consumer‑focused tips

• Enroll in time‑of‑use (TOU) plans – Shifting HVAC and EV charging to mid‑day slots can lower monthly bills by up to 15 %.
• Install smart thermostats – Automated temperature setbacks during peak demand periods can save 5‑10 % on electricity use.
• Consider on‑site solar – Net‑metering credits for residential solar installations offset rate hikes, especially in daylight‑heavy months.

Real‑World Example: Google’s Kearney Data Center

• Energy profile: Consumes ≈ 120 MW, ≈ 30 % of its load sourced from on‑site wind turbines and a 40 MWh battery system.
• Utility partnership: Signed a 15‑year Power Purchase Agreement (PPA) with NPPD, locking in a fixed rate and providing NPPD with a guaranteed renewable load.
• Outcome: Reduced peak‑demand contribution by 8 MW through workload scheduling, mitigating the need for immediate transmission upgrades.

Benefits of Grid Modernization

• Improved reliability – Automated fault detection cuts outage duration by an average of 22 minutes per event.
• lower long‑term costs – Investing in flexible resources (storage, demand response) reduces the need for expensive transmission expansions.
• Environmental gains – Higher renewable penetration reduces CO₂ emissions by an estimated 1.4 MMT annually.

Practical tips for Businesses Facing Rate increases

1. Conduct an energy audit – Identify inefficiencies; a 5 % reduction in PUE (Power Usage Effectiveness) can translate to meaningful cost savings.
2. Leverage virtual power plants (VPPs) – Aggregate distributed resources (solar, storage) to participate in ancillary services markets.
3. Negotiate PPA terms – fixed‑price contracts shield against future rate hikes while supporting renewable goals.

Key Takeaways

• Nebraska’s power grid is under unprecedented stress from the data‑center boom and rising residential/EV demand.
• Rate hikes are a direct response to necessary infrastructure upgrades and operating cost increases.
• Proactive grid modernization, smart‑metering, and collaborative utility‑customer programs can balance reliability, affordability, and sustainability.
