Green California Summit October 2018

Anna Ferrera, Executive DirectorSchool Energy Coalition

School Energy Coalition – Energy and Water from a School District Perspective

• SEC provides the most up‐to‐date and relevant information to our members on how decisions in Sacramento may affect energy and water decisions on their individual school sites. Our work with state agencies, utilities and professionals in the field is well‐known.

• SEC is called upon regularly to provide views on K‐14 school concerns regarding utility rates and energy and water policies. SEC members are invited to share and present their experiences directly with state decision‐makers.

• SEC helps schools get better control of utility bills and help state efficiency and renewable funding programs work best for schools.

• We share information on how school facility and construction funding programs can be leveraged to make energy and water projects go further.

Individual School Goals for Energy and Water Efficiency

• Prop 39 helped LEAs see the value of efficiency and renewable projects. Sharing our results will be important as projects are completed by 2020 ‐‐ Savings in Kw and $ to make the case for more funding.

• California schools want to take the next steps toward deeper retrofits, toward Zero Net Energy and to become more resilient in case of disaster or outage.

• Our individual projects will assist the state in meeting the new renewable and efficiency goals set by the Governor last month at the Global Climate Summit.

What are the SEC Messages for 2019?

• Build on the Success of Prop 39: Showcase Successful

Projects Moving Forward ‐ Share info with SEC

• Commitment Made by Schools: LEAs have Spoken for Over

98% of the Five‐Year Funding

• We can assist California with Climate Goals through Efficient

and Resilient Schools Statewide

• Real “Climate” Change through School Facilities – Student

and Community Awareness

How? More State Funding for the Clean Energy Jobs Creation Fund (Prop 39)

• The Prop 39 Program averaged $349.6 million over the five‐year period ‐ 2019 Statewide Request

• Corporate Tax Revenue under Prop 39 still coming in• School projects are showing success ‐Need Your Data!

SEC will fight for ongoing K‐14 School Energy grants by application in the 2019 State Budget cycle through the Clean Energy Jobs Creation Fund; and help schools leverage this funding with Prop 51 and a new 2020 State School Bond with an energy efficiency and Green renewable component.

Distribution Panel

29

- Segregate emergency loads onto own defined electrical panels. - Automate the transfer from grid power to emergency power.-No Manual interventions needed.

New Build/Major Renovation

- Use existing electrical infrastructure to distribute emergency power. - Operations plan to manually switch off circuit breakers that do not feed emergency load.

Mid-Life Cycle

- Install ATS to switch between grid power and solar/storage loads. Ex. Add festival style downstream power distribution equipment.

Older Infrastructure

ELECTRICAL INTEGRATION OPTIONS

Technical Feasibility

30

• Normal Operation PV and Battery are Grid Tied

• During an Outage – ATS transfers PV/Battery to Emergency Power ‘Tap Box’

• Each room to be provided with power has a 208/120V, 50A “Spider Box”

• Extension cords transport power from Tap Box to Spider Boxes

• Load on each Spider Box is limited in some cases due to volt drop

Emergency Power Strategy

208/120V 250A, 5 way Tap Box

208/120V 50A, Spider Box

208/120V 50A, 100’ power cord. Connect together for longer runs

31

• Plug loads are connected to Spider Box. Typically 6 receptacles per Spider Box.

• Lighting via LED pole lighting - daisy chained via local extension cords

RESILIENCY


ENERGY SECURITY DRIVERS – DOD RULES & GUIDELINES• Example: Department of Defense Instruction

4170.11, Energy Resilience Change• Requires DoD components to determine and

annually critical energy requirements.

• DoD components to identify, design & install primary power and emergency energy systems for critical energy requirements.

- Not limited to traditional standby or emergency generators.

- Distributed & renewables, diversified fuel supply, upgrading, replacing and maintaining current generation systems.

- Systems shall include automatic transfer, inverters, and black-start capabilities and shall consider fueling and storage.

- Requires DoD components to maintain systems & provide trained operators.

- Full scale & routine testing of emergency & standby systems. (annual full-scale, routine semi-annually)

Page 41

• Example: Department of Defense Instruction 4170.11, Energy Resilience Change

• “DoD Components are encouraged to use alternative financing or utility privatization arrangements in pursuit of energy resilience projects, when they are life cycle cost effective.”

• “DoD Components shall pursue opportunities that reduce life cycle costs, to the maximum extent practical, such as participation in peak shaving, demand response programs, ancillary services markets, and other financial incentive programs.

THE SPECTRUM OF GRID RESILIENCY

43


APPROACH TO ENERGY RESILIENCY

44


HOW TO PAY FOR RESILIENCY

45


• Community Choice Aggregation (CCA), Public – Private – Partnerships (P3), Asset privatization

• Private sector capital – e.g., Obama’s presidential challenge (Federal)

• PPA’s increased renewable energy

• Utility procurement

• Asset privatization (long-term leases)

• Operational costsno longer addressableby “using less”

• Maximize District’savailable fundsthrough leverage

COMMODITY & FINANCIAL STRUCTURES


SAMPLE PROJECTS – MARINE CORPS RECRUIT DEPOT PARRIS ISLAND

• Background• Critically outdated central heating and

power plant

• Minimal renewable energy (PV, incomplete wind)

• Established ICS network and prior demand management control

• Clustered loads

Page 47



• Solution• New $41M central heating and power plant

- 3.5 MW Turbine

- 60kpph HRSG

- Backup dual fuel boilers

- Backup and demand management diesel generation.

• Significant $20M expansion of renewable energy

- 1.6 MWDC carport-mounted PV

- 5.1 MWDC ground-mounted PV

- Restoration of existing Solar Thermal DHW

Page 48



• Solution• Leading edge installation of $5M battery

energy storage system (BESS)

- 4 MW / 8 MWh

- Captures excess PV generation for retail credit

- Capacity maintenance agreement

• $1.5M Microgrid specific control system

- Builds on existing components

- Controls 15 circuit breakers and 12 generation sources.

- Load shed and optimized dispatch

- Demand management

- Cybersecurity features

- Expandable
