Three utilities, one engagement: ~$2.3M in annual savings across 40+ national apparel sites

Power-only procurement leaves money on the table for businesses with material gas and water spend. A national apparel retailer brought all three utilities — plus renewables advisory — into a single engagement, and the breadth of scope drove the recovery.

What was happening before Pilot

The pattern across the portfolio fit a common profile for retail businesses where energy isn't a strategic focus:

  • Default utility tariffs on power at most sites — no competitive procurement strategy, no portfolio aggregation, contracts running at retail rates with no scrutiny
  • Default utility supply on gas — substantial markup over wholesale across HVAC and water heating load
  • Water bills paid without audit — sewer charges calculated as a flat percentage of water consumption, regardless of how much water actually entered the sewer; tariff classifications inherited and never validated
  • Renewables on the agenda, off the timeline — corporate sustainability commitments existed; the implementation framework didn't
  • No portfolio view — utility spend was a line item in the financials, not a managed function

For a 40-site portfolio with $4.5–5M in spend, the cumulative inefficiency was substantial. The first audit alone revealed material recoverable value across multiple categories — much of it through corrections that didn't require any operational change.

What Pilot did

A comprehensive utility engagement across four coordinated workstreams. The breadth was deliberate — recoveries in any one category alone would have been meaningful, but together the workstreams compounded.

1. Power procurement

  • Aggregated procurement across all sites by utility territory, leveraging portfolio buying power instead of site-by-site retail tariffs
  • Layered hedging with documented trigger prices replacing reactive renewal patterns
  • Multi-supplier portfolio matching each market with the supplier offering the best rates and contract terms
  • Demand and tariff optimization — capacity charges, demand calculations, and rate-class assignment reviewed for each site and corrected where appropriate

2. Gas procurement

  • Competitive gas supply across deregulated gas markets, moving sites off default utility tariffs onto market-rate supply with layered pricing
  • Aggregated buying across the portfolio, achieving rates that no single site could negotiate independently
  • Operational coordination with HVAC and water heating systems to optimize gas usage during high-demand periods

3. Water solutions

  • Comprehensive bill audits across 40+ accounts — tariff misclassifications corrected, calculation errors caught, refunds and credits pursued where applicable
  • Sewer credit applications for non-sewered water consumption (irrigation, cooling tower evaporation, certain process uses)
  • Flow control optimization at sites where the analysis supported the investment — typically delivering 15–25% water reduction with no operational impact
  • Sub-metering installations at sites with significant irrigation or process water use, enabling credit applications and ongoing operational visibility

4. Renewables advisory

  • REC procurement coordination aligned with the corporate sustainability framework — vintages, geographic attribution, and attribute claims documented for reporting
  • Green tariff evaluation at sites where utility-provided green options offered competitive economics
  • PPA structuring where the portfolio scale supported a long-term offtake — a smaller-portfolio approach than national hyperscalers use, but the same strategic framework
  • On-site solar evaluation at flagship locations with appropriate roof or canopy space and supportive economics

What changed

  • ~$2.3M in annual savings across the engagement, drawn from all four workstreams
  • Utility administration consolidated — 40+ sites, three utilities, single point of contact
  • Sustainability commitments operationalized — REC procurement, green tariffs, PPA structuring framework, all aligned with corporate reporting
  • Operational visibility improved — monthly portfolio dashboards covering all three utility streams plus sustainability progress
  • Internal team focused on leases, store operations, and growth — utility management no longer on the daily to-do list

3 + 1

utilities (power, gas, water) plus renewables advisory addressed under one engagement — breadth that single-utility procurement can't reach

Why this case worked

Several structural factors made this engagement deliver materially more than a narrower scope would have:

  • Multi-utility scope captured recoveries single-utility engagements miss. A power-only engagement would have addressed roughly 60–65% of total utility spend. Adding gas and water brought the remaining 35–40% into scope — and the recoveries on those were proportionally larger because they had been even less scrutinized.
  • Inherited inefficiency was substantial. 40+ sites of default tariffs, unaudited bills, and reactive renewals had accumulated real inefficiency over many years. The first comprehensive audit cycle alone surfaced recoverable value that more frequently-audited portfolios wouldn't have available.
  • Scale was right for the engagement. 40+ sites and $4.5–5M is large enough to justify portfolio-level analytics, aggregated procurement, and comprehensive audits — but small enough that internal energy expertise wouldn't be a sensible investment. External engagement was the rational fit.
  • Renewables fit the existing sustainability commitments. The corporate framework already existed; what was missing was the implementation pathway. Renewables advisory provided that without requiring new strategic commitments — just operational execution against goals that were already on record.

Bottom Line

For multi-site businesses with meaningful gas and water spend alongside power, scope breadth is where the unscrutinized value usually lives. Single-utility procurement engagements address the largest line item but miss the categories where inefficiency typically accumulates fastest. A 40-site apparel portfolio's comprehensive engagement across power, gas, water, and renewables delivered savings that no narrower scope would have reached.

Frequently Asked Questions

Why does a multi-utility engagement deliver more than a power-only engagement?

Most commercial procurement engagements focus only on electricity. But for many businesses — especially retail, hospitality, manufacturing, and food service — gas and water represent meaningful portions of total utility spend. Default utility tariffs on gas typically carry significant markup over wholesale; water bills often have unaudited billing errors and missed sewer credits accumulating year over year. Engaging all three utilities together captures recoveries that single-utility procurement misses entirely.

What's special about apparel retail energy procurement?

Apparel retail load profiles are HVAC and lighting heavy, with predictable summer afternoon peaks driven by air conditioning across many small storefronts. Sites are typically small individually but aggregate across many leased locations spread across utility territories. Inherited from previous tenants or landlords, contracts often default to retail tariffs that don't reflect current consumption patterns. The aggregate spend justifies portfolio-level procurement; the small per-site scale means it rarely gets it without external engagement.

How does renewables advisory work for a smaller portfolio?

For mid-scale portfolios, renewables advisory typically focuses on REC procurement aligned with sustainability commitments, evaluation of green tariff options offered by suppliers, and PPA structuring where the portfolio is large enough to justify long-term offtake. On-site solar evaluation for properties where economics work — typically larger flagship locations with appropriate roof or canopy space. The scale doesn't always justify the largest PPA structures, but the strategic framework is the same as larger engagements.

Why are water bill recoveries so substantial?

Water bills are systematically less scrutinized than energy bills. Errors and tariff misclassifications accumulate over years. Sewer charges based on water consumption (the default assumption that all water enters the sewer) often miss substantial non-sewered use — irrigation, cooling, evaporation. Flow control technology can reduce consumption 15–25% with no operational impact. For a portfolio that has never been audited, the cumulative recovery across audits, sewer credits, and flow optimization can be substantial — sometimes 20–29% of total water spend.
