6. RFI Feedback & HAS Planning Decisions – Steve Cornell

7. RFI RESPONSES - SUMMARY
Received 11 Responses from Energy Providers, Suppliers, Contractors and Consultants as Individual, Joint-Ventures or Teams
Responses Reflected Extensive Experience in Delivery of Energy Solutions for International, North America, Texas and Houston Region Clients
Responses Represented the Range of Energy Alternatives, Including On- Site and Off-Site Solutions
Responses Included CHP, Solar, Bio-Fuel and other Renewable Resource Solutions
A Number of the Respondents Included Business/Financial Options (Rate- Based, PPAs, DBOM, DBOM-F, P3, etc.)

8. RESPONDENTS– KEY CONSIDERATIONS
Right sizing of CHP system is dependent on correct energy profile data.
Early Engagement with Texas Commission on Environmental Quality (TCEQ) is Recommended.
For On-Site CHP, Adequate natural gas pressure and capacity must be verified; consider uninterruptible gas contract.
Phasing and sequencing of the new and modification of existing energy infrastructure must be carefully planned to maintain facility operation.
Consider use of thermal storage.
Early planning of site limits and logistics must be undertaken.
Suggested final pricing for partnership on an “Open Books” basis.
Consider the treatment / transfer of assets at end of contract term.
Leverage global supply agreements with Tier 1 manufacturers.
Consider renewable energy PPA supplemented by natural gas generation.

9. HAS PLANNING CONSIDERATIONS
The Project Team is considering delivery of the Energy Initiative (EI) Project as a DBOM-F, P3, PPA, or a combination thereof.
Proposals for the EI project must deliver the best long-term pricing structure for supplying energy to the City, and meet the previously defined goals of reliability and resiliency for IAH.
If an onsite CHP solution is selected as the EI solution:
There is currently no intent for an on-site solution to export power to the Grid other than what may potentially used for other City of Houston demands.
It appears that a CHP on the order of MW rating would be acceptable with respect to meeting the IAH Central Terminal Area (CTA) and the existing Central Utility Plant (CUP) loads.
It is understood that a CHP plant solution up to a nominal 45 MW can meet TCEQ emissions limits; this will require validation by the selected EI developer, if this solution is selected.

Option

11. HAS PLANNING CONSIDERATIONS
The interconnection of the new Enabling Landside Utilities (EUL) Project to the Energy Grid will be via a new kV substation and a Energy Provider-Owned switching station, both located in the vicinity of the existing Intercontinental Substation kV circuits would be extended under the airfield to the Electrical Power Station (EPS) near the existing CUP, and also connect to any installed CHP.
The above EPS may be included in the scope of the EI Project, as well as the kV feeders crossing the airfield.
The EI Project may include modifications to the existing CUP, such as replacing the existing steam turbine chillers which are near end-of-life.
The EI Project may also include assuming responsibility for O & M of the kV system from the EPS and up to final connections at terminals served within the Central Terminal Area as well as the CUP.

12. HARC Feasibility Study Overview – Darrell Thornley

13. CHP Feasibility Analysis George Bush International Airport (IAH) Progress Update
April 27, 2017

14. US Department of Energy CHP Technical Assistance
The US Department of Energy sponsors CHP Technical Assistance Partnerships across the US to educate on CHP and provide technical assistance
HARC, a non-profit research organization, operates the CHP TAP for our region
HARC is completing a Feasibility Analysis for CHP at IAH

15. IAH Feasibility Analysis
The feasibility analysis evaluates:
Load profiles
Utility rate structures
Potential unit sizing
High-level cost estimates
High-level payback analysis
The purpose of the feasibility analysis is to determine if a CHP is a technically and financially viable option for energy supply at IAH.

16. Preliminary Sizing Considerations
Approximately 18MW CHP system would generate 100% of thermal demand & over 90% of average electrical demand (~40% of peak electrical demand)
35-40MW could cover 100% of electric demand
Higher cost, depending on design also higher resiliency
How to best use additional thermal?
Optimal equipment configuration? 2 x 18MW? Combination of steam turbines and recips?

17. Possible Location 1
Possibly most cost effective location, tight plant footprint, limited construction laydown, etc.

18. Possible Location 2
Most space available, but longer piping runs significantly increase costs

19. Possible Location 3
Adequate footprint and construction space, piping/conduit under runway are significant costs

20. Next Steps
HARC submitting feasibility analysis to DOE for final review
HAS will consider information in the feasibility analysis along with information provide by vendors under the RFI process as it develops an RFQP

21. Open Discussion

22. Energy Initiative Project – Next Steps

23. Next Steps
Proceed with procurement via public bidding process – 2nd – 3rd Quarter 2017
Finalize selection of Energy Initiative solutions and delivery options for preparation of two-step RFQ/P package.
Issue, receive & evaluate respondent’s Statement of Qualifications (SOQ).
Establish short-list of respondents to seek Technical & Financial Proposals
Receive & evaluate respondents’ Technical & Financial proposals
Award Energy Infrastructure Contract – Target is to award by end of 2017.
