by 4.5 million, gig, sorry... pounds, each year, the green housing gas, contribution from electric conception here in san francisco and relative to getting electricity from the pg&e portfolio and we have incentives that here, these go solar sf incentives are available to our power enterprise customers as well as to non-customers. you know the pg&e customers. and in terms of opportunities for collaboration, and improvement, with the department of environment, cal referred to the financing option, that is certainly, promising and not just beyond bill financing option, but how we can really make sure that we are leveraging the go solar sf dollars in the best way. and that will be one of the areas that we will be focusing on for this coming year and on improvements for the go solar sf program. >> and here, on this slide, you
quote
3:31 pm
can see, the go solar sf workforce, hires by zip code here in san francisco. and the larger bubbles, and near the zip code numbers indicating the larger number of residents who are employed in the workforce, through the workforce development program, on go solar sf projects. moving on then, to our customer municipal solar, mr. carlin at the opening of our day, talked about the power enterprise and we serve largely municipal targets and we serve at power provider for the hunters point neighborhood and the shipyard, project, and that redevelopment project. and these customer municipal, solar facilitis that i am talking about are largely on the city, owned roofs. and our newest, here at symphony hall and the two that
3:32 pm
we energized and dedicated and we have over the years a list of projects that i am showing total of 2.5 mega watts of the roofs with the solar on them provided by sfpuc. and looking forward, we are our ten-year capitol plan has us dedicated about $12 million dollars of the net operating revenues to the additional facilities and you will see that in this particular fiscal year, are targeted towards the city hall solar and, downtown high school. and some other high school facilities that we expect to be installing solar on over the summer break. and we also have some renewable purposes, cal mentioned the sunset solar project that is photographed here and that is not a doctored photo and it really shows up and glows out on the sunset and we have five, mega watts of solar and that is
3:33 pm
the purchase agreement and so we purchase the output and the performance risk for the facility are held by the facility own and her we purchase the output and also to the extent and the clean power sf program is implemented and i heard that there is interest in us talking about that as well today, chair. and that would be a 100 percent renewable program. and it would be largely wholesale purchases of california, compliant renewable product. and moving then to the customer efficiency. and we have ten million dollars, set aside of our net operating revenue and our ten year capitol plan to send on energy efficiency and improvements for our customers facilities. and first off, we have 1.62 million of that dedicated to the civil center and sustainability district. and that is a program where we
3:34 pm
look at whole building upgrades driving for lead certification in the historic district and not only the historic are included however, the symphony hall is included and so, is the public health facility and so we have a miss mix of building tips that we are seeking the lead certification for and the city hall in particular, we are striving and this year, for a lead platinum or a gold for this facility. >> yes. >> our general fund, our general fund, program, and we are dedicating $5 million in our ten year capitol plan for that, and for that facility. >> excuse me, we are going to call the sheriff up here right now, you will be escorted out
3:35 pm
3:36 pm
3:37 pm
>> five million over the capitol plan and that is a directly installed program and so we identify together with the customer departments and the opportunities for the energy efficient improvements and we perform 100 percent of the work associated with that and it is the opportunity for the general fund departments to work with us and they provide us access to their facilities and we take of everything else and it is a program. and we also fund and are implementing improvements on our street light system, you know, we have an aging street light system and we have about, 18,500 street lights that are cobra street lights in san francisco that we will be converting to, you know, switch out the lamp, and the old style lamp and put in an led lamp.
3:38 pm
and a wireless controlled so we will be able to operate. and not only from the hours perspective but from a person perspective because the life of the led lamps is longer the enterprise customer and these are customers that range from the port, facilities like the shipping folks who to the cruise ship dock, where they come in and the floating otells basically and switch over from the marine power to the shore
3:40 pm
the investments themselves we funded the audit there at the airport, and then the airport took that information and sunk some additional money and time into the improvements implementing the measures, and so that is a good example of the type of enterprise customer program, implementation that we have seen. and then, finally, we have had a number of customer departments come to us and say, look, we are going to be making improvements on our facilities, and we know that you have the expertise on energy efficiency and we would like to pay you to lend that expertise to the facilities improvements and so that is where the green commissioning and design review program comes into. and focus on the new construction and the retrocommissioning and really it insures that the city is building energy efficient in, when they make those facility and improvements and so a good example of that is the recently opened public safety building. >> and with that, i think that i have given you a good teaser
3:41 pm
on the different things that we do and i am happy to answer any questions that you may have. thank you. >> thank you. and if i could ask a quick question, and we talked about it on the commission of the environment and the folks that we talked about today and can you give us status report on clean power sf? >> yes. so, we are and we are actively cooperating collaborating with the lasco folks in performing some additional study on the feesbility on pursuing the clean power sf and we are also aware of the feesbility study ordinance that supervisor avalos sponsored along with a number of his colleagues, supervisor colleagues. and so we are in assistance mode on those two efforts that really are looking at the feesbility of joining or
3:42 pm
otherwise working with marine clean energy, or self-performing community choice ago agree gaysing program through the las co-study performance work. we are standing ready once the policy makers have resolved ongoing forward approach to go forward but at this time, our focus really is on operating and maintaining our system and making sure that we are maintaining the financial stability and feesbility of continuing to operate. that core function that we have. >> okay. thank you. >> you are welcome. >> colleagues? commissioner josefowitz has a question. >> given that the cost of the power is so low, how do you think about sort of the energy efficiency up grades, for instance, or solar on municipal
3:43 pm
buildings, which would make a lot of sense financially, to most of the normal customers. but, which might not sort of pencil out financially with the cost of the power. >> so to take, first, the low cost of the power and how it works for energy efficiency. you know, the enterprise customer departments and the enterprise, rates to paying the customers that we have are paying the rate that they would otherwise be charged by pg&e and so they have the incentive to make those. and the general fund departments pay the rates that are from 35 to 62 percent below what they would pay if pg&e were the electric provider and they don't have the electric incentive to make the investment and which is why for those customer departments we are performing the soup to nuts service and making the investments ourselves. and that frees up the kilowatts
3:44 pm
that are not consumed at that department to sell at a rate that is more advantageous to us than those highly subsidized rates that the departments pay. >> so, if you save a kilo watt hour you can sell at a pg&e or a wholesale? >> today it is largely at a wholesale rate as our customer base grows, for example, as the hunters point shipyard neighborhood develops and our customer base grows, the hours could be sold at an rate that is more comparable to the pg&e rate and we factor that into the economics of the decision and with respect to the solar and the systems that we have installed it and that they are paying for completely are a more expensive resource, than
3:45 pm
the hetchy resource, absolutely, but it still makes sense for us to diversify and make the investments where we have the opportunities here in san francisco. >> and is there a plan to put the solar on every municipal roof top, where it would not, or whether it would otherwise not be something preventing it like the shade or the tremendous amounts of shading or tear down the building in a few years or something like that. >> not every municipal roof top is suitable for the solar and we have identified a pipeline of of potential projects, not just on municipal solar roofs, but also on land that the city owns and so, there are opportunities for the ground mounted solar, and today, we are a fully resourced utility and we have all of the kilo watt hours to serve the customers and were the base to grow and then it will make sense for it to develop more of those facilities, but do we have a plan to cover every municipal roof? no, i can't show you a document
3:46 pm
that says that, but we have evaluated those options. >> and have you evaluated, sort of the ground mounted solar, in the city limits or the land owned by the puc outside of the city? because you must have tremendous rights of way going out sort of to other places? >> yes it is mostly outside of san francisco. and in the ground field areas that we have looked at. but, we most of the opportunities are outside of the city, and frankly, they are more economic outside of the city not just because of the cost of the land but also because of the solar exposure and the solar opportunities are greater and so for the same solar panel located in san francisco and you will get more hours produced in senol than in san francisco.
3:47 pm
because it makes more sense for us to look at those opportunities as well. do you have from my interest, sort of a back of the envelope number for how much solar could be developed on sort of the city or the puc owned land outside of the city. >> the type line that i mentioned of the development opportunities, includes, if the memory serves me, about 45, mega watts of development opportunities outside of san francisco. >> have you thought about, leasing out that land, to allow a private developer to are able to develop, the solar on it and then, sell it to, you know, back to the pg&e of the grid. >> yes. >> but that is an opportunity, that we could pursue, and you know, the lands that we control, first have a utility purpose. >> and the lands that we control, are largely controlled by the water department, or the water side of hetch hetch water and power and any arrangement
3:48 pm
that we make, will be the use of the land that goes to the utility purpose and that makes it attractive for a third party to come in because they would want a long term commitment without those kind of caviots but it is something that we explored and it also would allow us to extract the value of tax credits and such that as a public entity we can't. >> only. >> yeah. >> and but we have looked into that and are evaluating those opportunities. >> and one more question, and sort of totally, and have you explored, sort of in-pipe, small scale hydro. >> yes, we have a development under development at the university of mound and it is a 200 kilowatt system and we are looking at going forward with that project once we have the financals nailed down on that. >> would that be a pilot
3:49 pm
project? >> right. that is the beauty of it it is gravity fed and when there is power flowing we love to generate the electricity from it and so the university mound would be our first and we have identified other opportunities that are larger, on the water system. and we are continuing to look at the feesbility, and the capability to pursue those projects. >> great. >> again, do you have a back of the envelope number for what, and the scale of those opportunities, are. >> and we have identified a little over 6 mega watts of opportunity. >> and then mainly a pumping station and sort of like the stations or like, it was just sort of really inpipe. >> it is, and it is a, and at the university mound, for example, we are looking at a pipe that goes into the reservoir. and there will be a by pass pipe with a generator and then, once the water by passes through the generator it will go through in the pipe into the
3:50 pm
reservoir and so it is opportunities like that. where we have the right flow, and the right land space, and the ability to implement, in-pipe hydrowithout getting in the way of water operations. >> those are the opportunities that we are looking at. >> thank you. >> you are welcome. >> commissioner gretsch? ... >> commissioner granavis. >> you did not mention the 100 percent renewable energy goal and i wonder if you could address how close we are to achieving that goal and will we achieve it with the projects that are described here today, if not, what else do we need to do. >> it was designed for the
3:51 pm
clean power sf to get there and we don't have another strategy specifically like the clean power sf and because the nice thing about that was it just converted the incoming electricity rather than having to do a tremendous amount to get it started. and we can look at some other options, and like, sat rating the city with solar. and unfortunately, if we blanket every single roof top in the city we will achieve 7 percent of the electric load. and therefore, even if we are able to reduce, 50 percent of our electric load through high amounts of energy efficiency, we would still only be at 14 percent. and maybe, with some additional brown fields or other sites we might be able to get 20 percent, but we are still going to be talking about importing large amounts of electricity, from renewable resources, in order to meet that goal. and alternatively, we can look at trying to get through the
3:52 pm
same 931,000 tons a year of diverted through some other means, like vastly reducing the number of vehicles on the roads in san francisco, and requiring more car sharing type of solutions, or going after natural gas use. and trying to really cut back on the amount of natural gas that is used in homes and businesses in cooking, heating and hot water, and particularly it is hot water and home heating, that are the primary uses of natural gas. and so, we would have to come up with both of technology, and the financing method and then the retrofit, method of getting out there and so we are looking at zero net energy homes and the home upgrade program, for example really targets the natural gas use and it does not get much at the energy and by
3:53 pm
sealing the house and insulating and you can reduce that heating load on the home and you can get that load down enough that you could actually convert and pull out the furnace and install a heat pump that will be solar powered from the energy from the roof. and you could have enough power on the roof, to power a heat pump and then you will not need the furnace any more or the hot water because you could use the heat pump technology as instead and so we are looking at those kiepds of solutions that is really a state wide effort and, and a lot of that effort, unfortunately has been focused on the new construction and we have got almost, zero single family homes being built in san francisco and very few of them and most of the new construction of the housing in the city is in the multifamily and high-rise, and we are trying to get the states zero net energy resources focused on existing buildings, so we can come up with a protoe types that would be applicable to san francisco to go after the
3:54 pm
natural gas load. >> and with a power, sf program or some other version of it, that needs to cca, and the description, house or how long will it take to meet the 100 percent goal? >> well, i think that the 100 percent is certainly aspirational because we do not have control over 100 percent of the electric customers in the city and even through the cca. you have approximately 20 percent of commercial load that are barbara might actually know the number better than i do on that, that are what we call the direct access customer and these are customers that are grandfathered in from the days of reregulation of the electric industry and they were allowed to go out and secure their own contracts. so those are contracts that are independent of the pg&e and will be independent of the
3:55 pm
clean power sf and it will be hard to get at that group and you have the folks that will opt out for whatever reason it is to opt out and even if it was to, be at the same price, and as the utility offers. so, it may not be able to achieve, 100 percent, but it will get us very close, and that could happen in a very short period of time. >> yeah and i would just, i would just add that cal's guess was pretty close, and the direct access side of san francisco's electric services is amounts to about 17 percent, and we provide about 12 percent from the own greenhouse gas free resource and the balance is pg&e and one of the opportunities for improving our greenhouse gas profile that cal had not mentioned is that pg&e is in front of the public utility commissions to have a
3:56 pm
green tariff option and our electric resource plan updates which was endorsed by the commission and our board of supervisors identified both the community choice aggregate program and the pricing programs that pg&e has now filed before the cpuc as options. and so, we have been my staff and i have been actively engaged at the california puc to make sure that is a program that works well within san francisco and it has the opportunities for the local development of renewables as well. and so it is, it is a dual path, the community choice aggregate option and the green tariff option. thank you. commissioner wald had a question but cal if i could just mention because i was at the and it might have been at
3:57 pm
the environment commission where you mentioned the statistic about roof top could get us 7 percent and i don't know if you get the boughts of insomnia and i wanted to figure that out and so i took a ruler and i kind of tried to figure out is that really right? it is only 7 percent of the entire city and so i went recently and found a study called roof top revolution and changing everything with the cost effective local solar and institute for the local self-reliance from march of 2012 and quote from the law and the golden gate law school that estimates 378 mega watts of roof top solar, which a non-peak demand is 6 to 700 so that is about 50 percent and a peak at 1,000 would be about a third is there a potential to
3:58 pm
revisit to figure out what the real number? >> the difference of what you are pointing out is the difference between a mega watt and a megawatt hour. it is going to produce about four and a half and there is a reduction in the storage and transition and the terms of hours per day. >> and i got you, and i know and it i have been around to know that and they say that the estimate per hour is 547 giga watt hours per year. >> yeah, but..., that is about right because we are running well over 6,000 giga watt hours, per year. is that? does that number sound right to you? >> so 547 giga watt hours and what percentage of 6,000. >> the food for thought and i will e-mail that to you, if you hear that number and you take a ruler and the sunset reservoir is a block and that is like nine and you know, like a map
3:59 pm
has a legend, like one inch equals whatever, and visually you will get a lot more solar and it is from the good folks but it might be worth internally of figuring out what the number is right. >> sure. >> i think that we do. >> it sounds like the numbers are actually very close. >> yeah i will give you my copy. >> sure. >> and we are happy to take a look at that too, at the puc, and you know not every roof is suitable for the solar and it is interesting when we are talking earlier about the green roofs and lid, and you know, there are opportunities to do more than just solar on san francisco's roofs. >> there are also physical restrictions that currently, the utility does not want more than 5 percent of solar at peak. than the demand that would be in that feeder, or in that distribution area. and so that makes it really
4:00 pm
impossible to really saturate the city with the amount of solar that we are talking about and however there is an opportunity of using the microgrids that you can island a particular group of buildings. and saturate them with solar and provide the energy storage that takes the excess hour and prevents at peak the system providing power to the grid. and it absorbs it all and uses that stored energy to provide the power for the rest of the day and evening. >> and having a microgrid is a way of also, doing, or being better prepared for the disasters. and providing more long term energy in case of a state wide black out, or the major earthquake or where the grid goes down for an over extended period of time. >> if you don't mind to take a look and see what and see how they did the analysis. >> sure. >> it just strikes anybody
