Government overrode BCUC on Hydro rates: Auditor General

The previous government used its authority to override the British Columbia Utilities Commission in setting Hydro rates, according Auditor General Carol Bellringer.

The Office of the Auditor General of British Columbia has released a new information report, Rate-regulated Accounting at BC Hydro.

Rate-regulated accounting shows the effect rate regulation has on a company’s financial statements. Rate regulation is the practice of controlling, or regulating, the price or rate a company charges its customers. A regulator that can act independently plays a critical role in rate regulation.

BC Hydro uses rate-regulated accounting. The British Columbia Utilities Commission (BCUC) is responsible for regulating BC Hydro.

For example, if a storm destroys the power grid and the repairs result in higher annual repair costs than expected, a regulator may allow a utility to smooth out the recovery of those costs from customers over future years. This is done instead of increasing rates dramatically in one year and then lowering rates in following years, or potentially incurring a financial statement loss.

A key role of the regulator is to ensure that the operating costs and deferred amounts are reasonable and can be absorbed in future rates.

“Rate-regulated accounting is a widely accepted practice in North America,” said Carol Bellringer, auditor general. “However, we found that government has largely overridden BCUC’s role in regulating BC Hydro and hasn’t allowed BC Hydro to charge its customers enough to cover its operating costs each year. It’s not clear what would have happened without this government direction.”

As of March 31, 2018, BC Hydro had 29 regulatory accounts, with a net regulatory asset balance of approximately $5.5 billion. In other words, BC Hydro has deferred $5.5 billion in expenses to be recovered from ratepayers. Some of these accounts are common, such as variance accounts to smooth out short-term variances associated with highly volatile or unpredictable costs. Other accounts, such as the Rate Smoothing Regulatory Account, are less common and defer unspecified costs to future years. The nature and balances of these accounts is explained more fully in the report.

Government has started to make changes that affect BC Hydro and BCUC. In November 2018, government removed the regulation that prevented BC Hydro from implementing appropriate accounting standards.

“Government has told us that more changes are on the way. We are waiting to see how these changes will roll out and how they will affect both BC Hydro’s and government’s financial statements,” said Bellringer.
