Renewable Energy and Energy Efficiency 1 Request for Information RFI-HRT-1800689

INSTRUCTIONS TO RESPONDENTS

I. Introduction

The purpose of this Request for Information (“RFI”) is to seek input from the interested public on technologies or strategies to integrate renewable energy and/or energy efficiency measures into the Honolulu Rail Transit Project (“HRTP”). The HRTP is a driverless, mostly-elevated light metro system which is being developed by the Honolulu Authority for Rapid Transportation (“HART”) along a 20-mile corridor between East Kapolei, , and on the island of Oahu. The system includes an elevated guideway structure, twenty-one stations, a Rail Operations Center (“ROC”), four park-and-ride lots, and other ancillary facilities. It will be the first driverless urban light metro system in the . Interim opening of the system (East Kapolei to ) is scheduled for fourth quarter 2020 and full opening (East Kapolei to Ala Moana) is scheduled for fourth quarter 2025. The rail system is expected to have about 121,600 daily boardings by 2030.

HART desires to launch the Project in a manner that promotes sustainability and resiliency, and also supports the State of ’s and the City and County of Honolulu’s targets for renewable power and ground transportation. Specifically, HART is seeking information on component technologies and integration strategies to implement best practices for renewable energy generation and distribution, distributed energy grid integration, and energy supply resilience and reliability. HART may consider the input received in response to this RFI in a future solicitation.

II. RFI Objectives

HART is interested in technologies and implementation strategies that address one or more of the following areas:

A. Energy Production: HART is interested in exploring the use of HART’s assets to generate renewable power or support the generation of renewable power for use by the HRTP. For example, there may be an opportunity to install photovoltaic panels along the parapet walls and sound barriers which line the guideway superstructure (within applicable safety and engineering/design restrictions) or elsewhere along the guideway.

B. Energy Storage/Distribution: Describe technologies to store energy, stabilize power fluctuations from train operations and/or renewable sources, peak load shaving, or integrate community grid distribution. Potential energy distribution solutions, such as electric vehicle charging for park-and-ride lots, transit buses, and maintenance trucks,

Renewable Energy and Energy Efficiency 3 Request for Information RFI-HRT-1800689 would also be considered. HART is also interested in the identification of any significant improvements in battery storage technologies within the last five years, since HART is planning to install back-up generators to power vehicles to the next passenger station in case of power outage.

C. Energy Efficiency: HART is interested in cost-effective technologies to improve the energy efficiency of the rail system, stations, and maintenance facilities. Examples could include measures to reduce energy consumption associated with traction power operations, cooling, lighting, and other system elements.

D. Resilience: HART is also interested in potential technologies that support sustained or emergency grid-independence and backup power supply for the system or possible surrounding community.

III. General Site Characteristics

HART is interested in responses that utilize the assets of the rail system, including the following:

A. Rail Guideway: The rail system operates on an aerial guideway which is approximately 19.7 miles (31.7 kilometers) in length. A 0.3-mile section of track adjacent to the Rail Operations Center is at-grade. The concrete guideway deck for a typical dual-track section is approximately 30 feet wide (9.1 meters) and is elevated approximately 35 feet (10.6 m) above ground level on average. At some locations, the guideway rises to approximately 70 feet (21.3 m) above ground level in order to clear highway ramps and overpasses.

An integrated parapet wall and sound barrier is located along both sides of the guideway, and is approximately 3 foot-3½ inches (1003.3 millimeters) in height (3’- 9’1/2” at crossover locations or 1155.7 mm). A 3’-9”-wide (1143 mm) emergency egress walkway is located between the standard-gauge tracks. The western half of the alignment (East Kapolei to just past Aloha Stadium) uses a plinthless direct fixation design to secure the rails to the guideway deck. This guideway construction has already been completed. The eastern half of the guideway superstructure is still in design and will use a more conventional design with plinths about up to 8” (203.2 mm) in height.

B. Rail Stations: There will be twenty-one stations. One station will be at-grade; all others will be elevated. Three stations will have a center platform which is 30 feet (9.1 m) wide; all other stations will have dual side platforms which are 12 feet (3.7 m) wide. Platforms will be 240 feet long (73.2 m) and will be equipped with platform screen gates in order to prevent passengers from falling onto the tracks.

Renewable Energy and Energy Efficiency 4 Request for Information RFI-HRT-1800689 C. Rail Vehicles and System Sites: The rail system will use conventional steel-wheel trains operating on steel rails. Traction power will be supplied by a 750-volt DC third-rail system. Each train car is about 64-feet in length (19.5 m), and the cars are semi-permanently coupled into four-car trainsets which are 256-feet in length (78 m). Each four-car trainset will have 188 seats, and will have a total capacity of 600-800 people. A maximum of 17 trainsets are expected to be used in peak operation when the system opens, and a total of 20 trainsets are initially being acquired. Average operating speed, including station stops, is 30 miles per hour. It will take about 45 minutes to travel along the entire length of the corridor from end-to-end. Initial operating headways will be about 5.6 minutes during peak periods, and 11 minutes off-peak.

D. Rail Operations Center: The ROC is a 43-acre site located near the middle of the rail line. The ROC includes several building facilities, equipment, and features a fully automatic, central yard control system that supports HRTP’s system operations and maintenance. The ROC also houses the system’s Operation Control Center (“OCC”). The ROC’s total building area is about 129,000 square feet (11,980 square meters).

E. Traction Electrification: The Traction Electrification System (“TES”) is designed to supply power to trains for safe, efficient, and continuous system operation. There are a total of fourteen (14) Traction Power Substations (“TPSS”) located along the alignment and at the ROC. Each TPSS is rated at 3,000 kilowatts (kW). Primary power to the TES is provided by three-phase alternating current (AC) supplied by Hawaiian Electric Company (“HECO”). Each TPSS converts the 12.47-kilovolts (kV) or 11.5-kV, three-phase, alternating current (AC) power received from HECO to 750- volt Direct Current (DC) power for distribution to train propulsion and auxiliary (hotel load) systems via a contact rail. Rectification is possible by diode-based 12- pulse power rectifiers with one transformer-rectifier unit (“TRU”) per TPSS. The TES also includes two Gap Breaker Stations (“GBS”).
