AI summary The discussion addresses the design of a facility as either a back-pressure or condensing/extracting system. Synapse's evidence is referenced, noting that sawmills are a reasonable basis for the tariff. A condensing/extracting system is favored due to the variability in steam load from dry kilns and the need for a system that can operate independently, despite higher capital costs.
Q. How should capital cost be allocated between the electricity generated and steam used for process heat? - A. We do not agree with the rationale that the base cost of the boiler should be borne solely by the steam host. The evidence pres...
AI summary The response argues against allocating the boiler's base cost solely to the steam host, suggesting instead that both the steam and electrical users should share the capital cost and fuel expenses. The rationale is based on the intent of the COMFIT program to promote renewable energy and the risk of relying on steam sales for revenue.
Q. What is the assumed availability of the facility? - A. Synapse considered an availability of 85% (60% at full extraction and 25% at full condensing). Based on dozens of facilities we have constructed over the last 30 years, we would exp...
AI summary The respondent recommends using a 90% availability rate for the facility, based on historical data and experience, arguing that this will encourage operators to maintain the facility and extend its lifespan.
Q. What is the calculated electrical usage of the facility? - A. The CHP facility will utilize a portion of the power it generates which is known as "parasitic loss". This power is used for the fans, pumps, motors, lights, etcetera in the...
AI summary The CHP facility's electrical usage includes parasitic losses of 348 kW, which are not considered in Synapse's calculations. This loss accounts for 14.4% of generation in condensing mode and 21.7% in full extraction mode.

It highlights the assumptions made about site access, soil conditions, and the availability of resources during construction and commissioning.
Q. Does ANSS agree with this approach? A. No. Since the purpose of the COMFIT is to procure renewable electricity, the ANSS does not believe that it is justifiable to approach the evaluation from the perspective of a boiler only scenario w...
AI summary ANSS disagrees with Synapse's approach to evaluating the COMFIT project, arguing that it unfairly places the cost of shared steam resources solely on the heat user. ANSS believes both the heat user and electricity rate payer should share the cost, as both benefit from the shared steam resource. Synapse acknowledged that some steam generated in a COMFIT CHP plan benefits electricity users.
Q. What mechanism would the ANSS suggest to deal with the fuel risk? - A. We would suggest two possible solutions to mitigate fuel risk: - 1. A fuel adjustment mechanism whereby the cost of fuel is simply passed through to the electricity...
AI summary The ANSS suggests two mechanisms to mitigate fuel risk: a fuel adjustment mechanism similar to NSPI's approach and a CPI/Diesel index with periodic re-openers to adjust fuel prices. The re-opener would require CHP COMFIT participants to submit fuel cost data and ensure consistency and market incentives for cost efficiency.
Data Granularity Our preference is toward a model that allows for enough detail to provide a fair representation of the cost of generating electricity with a CHP plant. We would error on the side of greater detail rather than less. The Ver...

AI summary The document argues that requiring sawmills to use backpressure turbines is financially risky, as shutdowns due to poor lumber market conditions would lead to fixed costs for the power plant that cannot be covered by revenue. This would compound existing losses and make CHP projects unfeasible under current market conditions.
Why a Condensing Turbine with Extraction Makes Sense In order for sawmills to participate and for projects to be able to attract debt the operation of the power plant has to be decoupled from the operation of the sawmill. A condensing turb...
AI summary A condensing turbine with extraction allows sawmills to decouple power plant operations from sawmill activities, providing flexibility during shutdowns or low production periods. This design supports revenue generation during difficult market conditions, reduces financial strain, and enables participation from community organizations with lower heat load demands.
