For PacifiCorp in Oregon, testimony in Feb 2020 in regard to why the company was systematically underrecovering fuel and purchased power costs relative to forecasted amounts allowed in rates. He showed that there is an inherent cost to balancing variances in short-term power needs (e.g. due to unexpected load levels or unexpected changes in plant performance) regardless of whether the realized needs are higher or lower than had been forecasted. This is because excess demands tend to be correlated across a market and so will usually have to be purchased at higher than expected prices, while demand shortfalls will tend to have to be released at lower prices than the costs of covering the expected need. Either way, there is a loss (or an extra cost). He testified that there is no good forecasting solution for this, so it would be more appropriate to eliminate risk sharing of these variances and flow them through, subject to periodic prudence review adjustments. His testimony reviewed automatic adjustment clauses and risk-sharing for all major utilities in the US not operating in RTOs.
