Can LNT's Infrastructure Investments Support Long-Term Growth?

Alliant Energy plans nearly $3 billion of capital expenditures in 2026 and $13.4 billion through 2029, a roughly 12% investment CAGR, targeting 5-7% earnings growth through 2029. Contracted large-customer load, including 3.4 GW of data-center demand, is projected to drive nearly 60% electricity-demand growth by 2031; the company also received final permits for its 720-MW Bobcat natural-gas generation project. Consensus EPS is projected to grow 6.52% in 2026 and 7.25% in 2027, although LNT trades at 18.53x forward earnings versus a 14.48x industry average.

Analysis

LNT’s key issue is no longer load visibility but conversion economics: incremental data-center load is valuable only if regulators allow timely recovery of generation, transmission and interconnection spend without shifting stranded-asset risk to residential customers. The company’s valuation already embeds a meaningful execution premium, leaving limited room for a simple capex-plan re-rating; upside requires upward revisions to the authorized return/rate-base cadence or a demonstrable acceleration in contracted-load energization.

The flexible-gas build improves reliability but creates a second-order exposure to gas-price volatility, carbon-policy costs and potentially lower utilization if renewable/storage additions arrive faster than expected. More importantly, concentrated large-load contracts can raise counterparty and cancellation risk: a hyperscaler’s project delay could defer both usage revenue and the regulatory rationale for associated grid spend. Over the next 1-3 months, rate-case filings, interconnection queue milestones and customer-credit disclosures matter more than generic demand commentary.

PPL and FE offer a cleaner way to express the grid-modernization theme because transmission and distribution investment generally has lower commodity and utilization risk than new thermal generation. Contrarian view: the market may be underestimating the political backlash from data-center-driven retail-rate increases; that would favor utilities with more transmission-led capital programs and penalize companies whose growth requires sizable new generation approvals. The thesis is falsified if LNT demonstrates contracted-load conversion ahead of schedule while receiving constructive cost allocation and return treatment in Iowa/Wisconsin proceedings.

Key Decisions for Investors

• Do not add outright LNT on this article alone; maintain a watch position only. Upgrade to long exposure after the next regulatory filing confirms data-center-specific cost allocation and management raises 2027-2029 rate-base or EPS guidance. A guidance increase is the necessary catalyst to overcome the current valuation premium.
• Initiate a 6-12 month relative-value pair: long PPL / short LNT in equal dollar amounts if LNT’s forward P/E premium remains above roughly 25% versus the utility peer group. The trade captures greater sensitivity of LNT to permitting, large-load conversion and thermal-build execution; cover if LNT receives favorable rate treatment that explicitly protects existing customers from incremental large-load costs.
• Monitor FE as a transmission-grid beneficiary rather than chase LNT’s generation-led growth. Add FE only on evidence that Energize365 capital deployment is tracking plan and regulatory outcomes preserve allowed returns; the key risk is Pennsylvania/Ohio regulatory pressure or a deterioration in financing costs.
• Set an alert around large-customer contract quality: any disclosure of cancellation rights, delayed energization, deposits below expected network-upgrade exposure, or load forecast reductions should trigger a LNT de-risking review, as the equity downside would come through both earnings timing and multiple compression.
