Slashing commercial electricity costs while going green

This East Tamaki business was facing soaring commercial electricity bills that were eating into margins. With a large warehouse and office facility running heavy loads during business hours, energy was one of their biggest operating expenses.

They needed a solution that would significantly reduce opex while also improving their sustainability credentials — increasingly important for corporate clients and procurement requirements.

Key Pain Points

  • High commercial electricity costs impacting profitability
  • Heavy daytime energy consumption across warehouse and offices
  • Growing pressure to demonstrate sustainability credentials
  • Needed reliable, long-term energy cost reduction
