Frequently Asked Questions

What are typical business electricity rates in New Zealand?

Business electricity rates in NZ range from 15-25¢/kWh depending on usage volume. Small businesses (10-50 MWh/year) pay 20-25¢/kWh, medium businesses (50-200 MWh/year) pay 18-22¢/kWh, and large businesses (200+ MWh/year) get rates of 15-20¢/kWh through custom agreements.

How do business electricity rates differ from residential?

Business rates are typically lower per unit but include demand charges ($/kW) and higher daily fixed charges. Businesses also get volume discounts, flexible contract terms, and custom pricing for high usage. The overall cost structure rewards consistent, predictable usage patterns.

What is a demand charge and how does it affect my bill?

Demand charges ($10-15/kW) are based on your highest 30-minute power usage in the month. They typically apply to businesses using 50+ MWh annually. Managing peak demand through load shifting or demand response can significantly reduce these charges.

How much can my business save by switching electricity providers?

Business savings vary significantly by usage: small businesses can save $500-2,000 annually, medium businesses $2,000-8,000, and large businesses $5,000-25,000+. Savings depend on current rates, usage patterns, and negotiated terms with new providers.

What factors should businesses consider when choosing electricity providers?

Key factors include: unit rates and demand charges, contract flexibility, account management services, bill consolidation for multiple sites, green energy options, customer support quality, and additional services like energy audits or efficiency programs.
