Mainframe Refresh and Migration Fit the Bill for Energy Company

The Client

Our client is a $25 billion energy company serving millions of business and residential customers throughout the U.S. and Canada. They generate and sell electricity, natural gas, solar, wind and nuclear power as one of the nation’s leading energy providers, employing 29,000 people. 

The Challenge

There were three problems facing the IT group. The mainframe needed more power to handle the increasing workload, and it was time to refresh the equipment. Taking on either of these issues represented a substantial investment of time and money for the company. In addition, they wanted to reduce their mainframe footprint, and expense, over time as they migrate applications to other technologies.

Our client’s focus is on being an outstanding energy provider, and they were looking for an equally outstanding IT services company to help them effectively manage their infrastructure for today and for tomorrow. At the end of a competitive process, the company chose to partner with Ensono.

The Solution

The company’s business is driven by the critical applications—including processing meter readings, scheduling repair crews and billing customers—running on the mainframe.

Leveraging what we’ve learned through many migrations, we were able to bring several mainframes—totaling thousands of MIPS—to Ensono data centers, on schedule and without service interruption. In addition, we put together a migration plan to reduce the company’s reliance on the mainframe, and the associated expense, over time.

The Benefits

By partnering with Ensono, our client:

  • Increased workload and support consolidation
  • Reduced IT-related capital expenditures
  • Reduced reliance on mainframe

Since signing the mainframe deal with Ensono, the relationship has now expanded to include their open systems environment. We continue to operate for today and optimize for tomorrow.
