One of the most significant factors in pricing data centers is the power requirements. And it is one of the most overlooked and easiest areas to address in order to reduce overall data center costs.

The margin between data center power usage and capacity is important to consider when working with a US or Asia Pacific data center provider. Vendors in these geographies typically buy data center power based on usage and then resell it based on capacity. While it is not a simple matter to identify the actual cost a vendor pays for data center power, understanding and making use of the underlying cost and risk model can deliver significant savings for buyers.

Impact of Lower Data Center Power Costs

The vendor’s hidden margin – and therefore savings potential – can range from five percent to twenty-five percent of the total data center cost. This drives home the importance of investing time and effort to understand your vendor’s data center power costs, and working with them to arrive at a pricing model adapted to your usage. A strong negotiation strategy will include not only demands from the vendor, but an understanding of their constraints and risks.

Given that data center power costs are one of the largest cost drivers for data center operators and their tenants, both parties logically give significant weighting to data center power costs when selecting locations. In addition to the location and price model, variables that go into the final calculation of rates include utility bulk purchase deals negotiated by the data center vendor, power usage efficiency (PUE), and, of course the amount of power your infrastructure will require.

Negotiation Considerations

Being armed with power cost metrics is not the end of the journey. You still must work with the vendor to arrive at an agreement. The following are suggestions to consider as you approach your vendor:
