Energy Exchange: Federal Sustainability for the Next Decade

• Energy Manger for base since 2001 Utilities Energy Management  Supervisor

– Project Manager, Utilities Manager, Auditor, REM• Over $100M in project just energy– Multiple contracting vehicles

• Innovating technology testing an implementation• Not all technology works on all bases• Plants get expensive with distance– More pipe = more cost– Electric, natural gas, and other external sources have to be looked at along with current pricing

• Plan for the future growth!

Strategy/ Energy and Security Master Plan

• Central plant strategy− Provide high efficiency plants for tie into major utilities− Build or leave infrastructure to build to full potential− Lowers manpower requirements to maintain equipment− Simplifies systems at Bldg level− Requires close buildings for cost

• Energy management control System− Incorporate metering into the building controls− Simplify communications − Controls and monitoring of each building and system− Lowers manpower requirements with visibility to Bldgs

• Electricity production on base• Microgrid control system 

− Cogeneration plant to offset more expensive on grid power− PV systems for renewable energy− Advanced controls systems for future growth− Electrical grid controls− Communications infrastructure

• Individual Marines and Civilians – Last level of effort to save energy

Implementation

• Utilize ESPC for major infrastructure starting point/plants $57M FY2000‐2004 ($5.2M 3.5yr modified to 17 year)(30% to 50% of bill)− Cogeneration plant 1 – 7 MW Solar Taurus 70 turbine with 35 MBTU/Hr HRU ($16M 3.5yr payback 2000)− 3 Chiller plants – 6250 tons with lines and controls to over 40 buildings and 5 separate chiller upgrades 1000 ton ($)26M− 1.2 MW Solar Array− Fiber communications 

• End of year funding contracts $90M FY2001‐2009 (Army Corps Of Engineers UMCS contract Huntsville)− Building controls and metering for 150 buildings  and communications− Evaporative cooling to chilled water conversions 57 buildings with controls and communications− PV systems

• EIP/ECIP (HQ funded efforts for energy)− Building controls and Metering− PV systems and metering and communications requirements− Interior and exterior lighting with motion controls− Upgrade existing chiller plants with high efficiency Mag bearing chillers 1500 tons

• MILCON  $50M− Cogeneration plant 2 − Two 4.6 MW Solar Mercury 50 turbines staged based on loads with 16 MBTU/Hr HRU each− Two 650 ton Absorption chiller units and one 650 ton electric centrifugal− Two 20 MBTU/Hr hot water generators

• Future– Local projects M1R1 and M2R2– Due to low electricity costs and SIR/Payback

Security aspects/Mission Assurance

• Upgrade of incoming power lines from 38KW to 115 KV dual feed (Leatherneck substation)

• Ability to self generate 90%+ electricity– 130,000 MWH required– 123,000 MWH potential generation

• 7 Days supply of fuel for emergency– Diesel and propane

• Load controls capability– Building loads by HVAC– Grid loads by substation and switches

• Electrical grid operations– 60 switches with redundant line capacity

• Islanding and Microgrid– Working 10 MW Microgrid using Cogen/PV power– P1232 Microgrid project to parallel Cogen system and island whole

Energy affects

6

Requirements/Progress – Energy ‐30 % (FY15 ‐38.65%)   – Water ‐26% (FY15  ‐57.18%)

Energy savings efforts– Project oriented from FY 2000– Individual savings efforts FY2014

• Unit Energy Monitor Program• Use of meter data

Monetary affects– FY2000 baseline about $18M– FY12015 baseline about $12M 

(assuming everything operational)One turbine down costs about $4500/day

Power production– 16.4 MW 2 Cogeneration plants– 8 MW PV systems on line by end – 24.4 MW Total production capacity– Winter peak 15‐17 MW – Summer 24‐26 MW– Minimum import 5% standard generation

Challenges– Operations– Maximize generation for savings– I can install it but someone else operates and maintains

Utilities connections

• Contract required for State utilities to supply Federal Government bases (FAR requirements and GSA area wide)

• Use as a reliable source of power– For reliability do not disconnect from grid

• Interconnect requirements– All power sources require IA and inspection prior to operations– Over X MW requires reporting of active generation

• Coordination– Base and SCE/SCG account representatives in constant contact on growth 

issues and power and gas supply– Proper billing accounts and charges can be modified under certain conditions

• Benefits– Stability– NEM and Load reduction programs– Incentive programs SCE and SCG

• Learn and understand your local Tariffs– Look at your bill!

Controls Map

Advance controls systems make monitoring and controls at building and plant level easier with less manpower. Personnel must upgrade skill sets to manage the system with oversight

Lessons learned

• Direct burry PVC lines in vaults steel• Maintain your systems– Failures turn into large scale problems

• Complex controls programs– Staff may not like and may not understand

• Watch operations staff for minor changes– Can have a large affect on billing and operation– Like to make changes but are they necessary?

• Interaction of systems– Cogen plants and absorption chillers
