Pump optimization of steam generator site. The project application states that the project is to be implemented in two phases.

The second phase would include installing VFDs and or de-staging of pumps with additional control logic
Install two new heat exchangers E-2XA/B to preheat the boiler feedwater used to produce 250-psig steam. Install two new heat exchangers to preheat the boiler feedwater (BFW) which is used in steam generator waste heat recovery to produce 250-psig steam; the BFW will then use waste heat in the Heavy Cycle Oil (HCO) pump-around stream at the FCC Main Fractionator. This measure will increase the steam production rate while reducing the system pressure from 600 to 250 psig. Thus steam production at the gas-fired #6 swing boiler will be reduced. Natural gas consumed by boiler #6 will be reduced accordingly.
The project adds two heat exchangers on the Heavy Cycle Oil (HCO) loop to pre-heat boiler feed water (BFW). The recovered heat reduces the load on the 250 psig steam loop fed by the feed water system.

Conclusion:
The IOU project proposal would displace the FOG processed at the waste water treatment plant
to in-house processing at the applicant’s facility. This will decrease electricity generation at the
waste water treatment plant and require them to procure electricity from the grid. From the
system perspective, the net benefit to the applicant would be the displacement of natural gas
they are currently purchasing from the IOU with methane that will be produced from the
proposed project to process FOG. This benefit has to be compared with increased electricity
purchases from the IOU that the waste water treatment plant will have to make to substitute for
the loss of power produced using free biogas from processing the FOG. The net btu change is
unlikely to be positive because the source btu for additional electricity purchases will have to be
calculated at about 10,000 btus/kWh rate. The baseline condition though is electricity production
from available free fuel. While ED did not conduct a full comprehensive analysis, it appears that
displacing electricity generation from free fuel is unlikely to be a beneficial from the societal
perspective. ED does not find any net benefit from the proposed project and the project is
therefore not approved.

Memorandum: CPUC Staff representatives have performed a post installation site visit, reviewed the Installation
Report submitted by the IOU for this project, and participated in phone conversations with the IOU
and third party implementer. The IOU installation report estimates the ex ante savings for the
project to be zero therms, 309.2 kW peak demand reduction and 1,978,842 kWh.
The installation report baseline is based on five heatless desiccant dryers operating at all
times. During the site visit, CPUC Staff representatives interviewed a customer representative and
determined that the customer normally operated three or four heatless desiccant dryers before the
project was implemented. CPUC Staff representatives have worked with IOU representatives to
revise the savings estimates for the project based on an average of 3.5 heatless desiccant dryers
operating. Additionally, the analysis was revised to properly reflect the specific power curve for oil
free rotary screw air compressors and utilize the loaded and unloaded compressor power that was
measured during the post installation data collection.
The ex ante savings are approved at the IOU revised estimates of zero therms, 109.4 kW peak
demand reduction and 1,254,382 kWh.
CPUC Staff representatives request that the IOU submit a revised installation report reflecting the
approved savings also showing the final incentive. In addition please submit the IOU’s revised
savings analysis and the original raw post installation data that were collected for the project in 5
second intervals from July 1, 2013 to August 1, 2013.

Energy savings have been calculated using a greenhouse modeling tool that calculates energy
savings utilizing the eQuest energy simulation software. Model baselines have been developed
using a 2006 greenhouse baseline study that was performed by Green Building Studio for
PG&E.1
Dual Cool evaporative cooler retrofits onto multiple existing rooftop packaged air conditioning units at eight separate single story, large retail facilities in Climate Zones 2 and 13. the Dual Cool units pre-cool both the condenser and the make-up air supply.
Replace glass melter power supply with a high efficiency power supply. This project involves the beginning of a phased replacement of SCR controlled melter power supplies used for glass melters at a fiberglass manufacturing plant with more efficient
continuously variable voltage “Varivolt” auto tap transformers. The existing SCR power
supplies require mechanical cooling (chilled water and packaged air conditioning) to remove
heat. The Varivolt power supplies have an estimated efficiency of 98% and only require cooling
tower water to maintain their internal temperature in a safe range. This project proposes to
replace two power supplies. The remaining four modules are expected to follow at a later date.
The project entails installing 2 measures: 1) VFDs on new steam generator feedwater pump and combustion air fan, and 2) a split pass design of the steam generator in lieu of the standard single pass configuration.

The proposed project entails installing POCs on one hundred thirty (130) rod beam pumps at the facility. The POC will shut the well down based on downhole conditions, resulting in energy savings. The baseline equipment for this project is claimed to be the existing rod beam pumps with no controls.
The customer operates a poultry processing plant. This project affects three refrigeration circuits at the plant. Proposed measures include floating head pressure for all three circuits, evaporator fan VFDs for one circuit, suction pressure optimization for two circuits, and VFD compressor controls for one circuit.
The measure is to install blowdown heat recovery (heat exchanger) on the existing three boiler
systems (installed circa 2008) and use the recovered heat to preheat the makeup water. The
boiler water - which is pressurized, hot and dirty, and creates large volumes of flash steam and
possible disposal problems - is blown down to control the amount of total dissolved solids (TDS)
in the boiler. A new heat recovery system will reclaim large amounts of energy during this
essential process.

Heat Recovery Project: The project intends to achieve heat recovery by installing three measures. Dryer exhaust air recirculation, waste water het recovery, and flue gas stack recovery economizer.
NC Waste Water Treatment Plant Processes: As part of the construction of a new water
recycling facility, the EE measures include
the installation of aeration blower, DO
controls, low-pressure, high-intensity UV
lamps and fine bubble diffusers in the
oxidation ditch.
Process Compressed Air System Modifications: Install central low pressure blower systems, reduce high pressure compressed air consumption, and recover heat from blower system.
High Emissivity Coating on Furnace Refractory: The measure proposes to increase the heat
transfer efficiency by applying a proprietary water-based coating to refractory surfaces inside an industrial furnace.

LED Fixture, Linear Fluorescent Fixture, HID Fixture
This is a T-8 linear fluorescent and refrigerated LED lighting retrofit in 10 retail stores. This is
the customer’s 5th multi-site batch application under PG&E custom programs. The project
involves retrofitting existing T12 and first generation T8 lamp and ballast systems with high
performance 32W T8 and reduced wattage 28W T8 lamp and ballast systems at each retail store.
The project also involves integral de-lamping in the main sales area. The savings will result from
reduction in power draw of the proposed T8 lamp and ballast systems. This is a replace on
burnout (ROB) measure per program rules because it involves T12 replacement.
The measure is a motor control system that would shut off production line motors when not in
use. The control system consists of sensors and control equipment that continuously detects
manufactured bottles along either of the two packaging lines. The controls activate and
deactivate segments of the production line’s motors as needed. This reduces the idle run time of
the many conveyor and packaging motors by running the motors only when there is a product
load on a given production line. The control system will also have an emergency shutdown
mechanism to override the automated controls.
The natural gas energy savings portion of the project involves insulating steam & hot water bare
pipe surfaces including valves, fittings, traps and condensate return lines. For electrical energy
savings, insulation is also being added to chilled water pipes, fittings and valves.
