Unit cost reduction) or negative (i.e. unit cost increase). in estimating efficiency, we set out estimates of productivity improvements and input price changes separately. our approach is consistent with the academic literature on allowing for anticipated efficiency change (or “x”) in an indexed (“rpi”) price-cap regime, where.
We might then account for inflation using the chemical engineering plant cost index (cepci) or similar indexes. this allows us to estimate the capital costs (capex) of the plant very roughly. operating cost estimation. in academia, operating costs (opex) are usually estimated as a percentage of capital costs, often a nominal ten.
